COLOUR AND CONTROL MEASUREMENT
High-frequency contrast sensors for UV, VIS and IR range
SPECTRO-1 Series
The SPECTRO-1 sensors are contrast sensors that are able to record even slightest brightness differences almost in real time. The sensor features analog and digital signal outputs. With the optical fibre types (FIO) inspection can be performed both in transmitted-light and in reflected-light mode.
The use of different light sources (apart from the white-light version, versions with UV, red, blue, and IR light source also are available) makes it possible to perform measurements starting in the UV range, in the visible range, and through to the IR range. Because of the wide type range object distances of up to approx. 1000 mm can be realised.
The sensor can be easily parameterised with the SPECTRO1-Scope Windows® PC software. The scope function that is integrated in the software makes it possible to watch the signal characteristic quasi in real time.
The contrast sensors of the SPECTRO-1 series can inspect both passive and active objects. With the software the sensor can be switched from passive to active objects. The sensor's analog output provides information about the current contrast value, while the digital output can be used to check whether the respective object lies in the permissible tolerance range.
SPECTRO-1 contrast sensors feature an impressively high scan frequency of 200 kHz.
Two-channel sensor systems for a variety of applications
SPECTRO-2 Series
The SPECTRO-2 series now closes the gap between contrast sensors (SPECTRO-1 series) and color sensors (SPECTRO-3 series).
The SPECTRO-2 system can operate as a pure 2-channel system (quasi two SPECTRO-1 sensors in one housing), or as a comparative (normed) system in which one channel can function as a reference.
The Windows® operating software provides a large variety of evaluation algorithms, and combined with corresponding special fiber optics, of which an extensive range of different types is available, this sensor system is perfect for solving many different tasks.
The use of BICONE fiber optics, for example, allows high-precision, space-saving distance measurements also suitable for Ex areas (with quartz fiber optics and UV LEDs among others for distance measurements on glass surfaces).
A comparison of two IR wavelength ranges furthermore makes it possible to check the water content in objects such as textile or paper webs, wood, bricks, ceramics, and other building materials. Inhomogeneities of moved objects (e.g. chatter marks or defects on metal strips) also can be detected using fiber optics that are suited for such tasks.
For all applications wavelength ranges beginning in the UVC range (starting from approx. 250 nm) up to the IR range (up to approx. 2000 nm) are available both at the transmitter and receiver side.
We shall of course also be pleased to respond to your special requirements, because the system offers corresponding flexibility both with respect to software and hardware.
Color sensors (True Color)
SPECTRO-3 Series
With the SPECTRO-3 series there now is a family of color sensors that has been specifically designed for "true-color" detection ("human color reception") and high switching frequency.
The sensors can be operated both in AC and in DC mode, with integrated or external light source. With the included SPECTRO3-Scope software illumination can also be turned off with a simple mouse-click, which then also allows the color and brightness inspection of self-luminous objects such as LEDs, automobile tail lights, halogen lamps, or fluorescent lamps.
In the SPECTRO-3 series great importance was attached to a compact design and to the largest possible extent to a uniform appearance of the various types (M34 design or rectangular), which facilitates sensor installation. Up to 31 colors can be provided through the 5 digital outputs, the maximum switching frequency is typ. 35 kHz in case of the series SPECTRO-3 (M34 shape), SPECTRO-3-CL, SPECTRO-3-MSM-DIG, and SPECTRO-3-JR.
With the new SPECTRO-3-SL, SPECTRO-3-ANA and SPECTRO-3-MSM-ANA color sensor types the product range was extended with extremely fast color sensor types that now make it possible to reach scan frequencies of up to 90 kHz. These color sensor can learn up to 3 colors (or 3 color groups with up to a total of max. 31 colors). Information is output by means of two digital outputs, or with the ANA types additionally by three analog outputs.
Apart from a super-bright white-light source, a high-performance UV light source also is available, which allows the color and brightness differentiation of fluorescent colors without any problems. Different frontends make it possible to implement operating distances of 0.2 mm through to 500 mm, with detection areas of Ø 0.5 mm to approx. Ø 100 mm. The use of an optical fibre version allows applications in Ex areas.
Laboratory measuring systems
SPECTRO-LAB Series
The SPECTRO-LAB device series can be used for example, for the laboratory investigation of the fluorescence of samples of plastic granulate to be provided with fluorescent markers during production, but also of marked pellets gained from recycled material. The measurement is carried out in accordance with the 0°/45° measurement method.
Depending on the type of fluorescent marker, various light sources are used for material excitation: UVA, blue, green, red. The spectral evaluation (the respective device is equipped with a corresponding spectrometer) is performed either in the visible wavelength range or in the near infrared range, depending on the type of excitation:
UVA excitation → VIS spectrometer
Blue excitation → VIS spectrometer or NIR spectrometer
Green excitation → NIR spectrometer
Red excitation → NIR spectrometer
COUNTING AND TRIGGERING
Laser digital light barriers
D-LAS Series
The laser digital light barriers of D-LAS series work with visible parallel laser light. The use of round or rectangular apertures ensures a homogeneous light distribution in the laser beam. Smallest objects are detected even in case of a large transmitter/receiver distance. Dynamic correction of the switching threshold compensates the effect of dirt accumulation (with D-LAS1, D-LAS2, D-LAS-34, D-LAS-34/90).
These light barriers are ideal for positioning tasks.
With their sturdy metal housing and their high type of protection the laser light barriers of series D-LAS are designed for demanding applications in machine construction.
The features of D-LAS light barriers at a glance:
Collimated laser beam
The laser light beam that is emitted by precision lenses (asphere made of glass) allows the detection of smallest objects (e.g. threads) even in case of large transmitter/receiver distances (depending on type and aperture distances up to 100m).
Advantages:
-
Telecentrical design
-
Exact shadow projection onto the receiver
-
The distance of the measuring object from the transmitter or receiver over a wide range has no influence on the measuring signal
Homogeneous light distribution
The use of high-precision apertures in the transmitter ensures optimum adaptation to the respective application. Apart from a large variety of standard apertures special apertures can also be realized.
The aperture ensures a homogeneous light distribution in the beam and a sharp beam limitation.
Adjustable laser power
The laser power of transmitters of type D-LAS1, D-LAS2, and DLAS90 can be adjusted through the current control input (I-Control). With this input the laser also can be switched off, it can therefore be used for testing the laser light barrier (test input).
High positioning accuracy
In conventional light barriers the switching threshold is adjusted by means of a potentiometer. It depends on a fixed voltage (absolute value). As a consequence the switching point shifts with increasing dirt accumulation.
In the laser digital light barriers of the D-LAS series, however, dynamic correction of the switching threshold compensates the effect of dirt accumulation by way of continuous monitoring of the maximum value at the receiver. This means that increased dirt accumulation does not lead to a shift of the switching point.
Monitor signal
In addition to the switching signal the laser light barriers of type D-LAS1 and D-LAS2 also provide an analog signal. This "monitoring" of the analog voltage allows improved evaluation of the switching signal. The output also is suitable for measuring purposes.
Dynamic measurement
When an object passes through the laser light beam of a D-LAS1-D light barrier it triggers a voltage pulse whose pulse duration is independent of the time the object stays in the laser beam. The pulse duration is set to a fixed value of 10 ms.
Pulsating-light operation
If intensive external light sources must be expected in a laser light barrier application, it is recommendable for safety reasons to use a pulsed system (D-LAS1, D-LAS3, D-LAS90, D-LAS90-VACU). Due to the use of narrow-band electronic filters only the modulated light of the transmitter is detected. Even pulsed light sources such as flourescent lamps have no influence on the switching reliability.
Constant-light operation
In case of high switching frequency requirements a non-pulsed system can be used. Here external light suppression is ensured by means of narrow-band optical filtering. Therefore constant-light light barriers are suitable for fast processes or for measuring objects moving at high speed.
With the help of the analog output constant-light barriers of series D-LAS2, D-LAS-34, D-LAS-34/90, D-LAS-ED1 can also be used for measuring tasks.
Laser fork light barriers
F-LAS Series
The laser light barriers of F-LAS series allow the solution of complex problems (curve discussion, tolerance band monitoring, etc.).
Functional principle:
The signal at the analog output decreases proportionally with increasing laser beam covering.
Collimated laser beam:
The laser light beam that is emitted by a high-precision optical unit allows the very precise detection of smallest objects (e.g. threads) even in case of a large transmitter/receiver distance. The low divergence of the light beam almost completely reduces the measuring error that is caused by moving the measuring object from the transmitter in the direction of the receiver.
Homogeneous light distribution:
The use of high-precision apertures in the transmitter ensures optimum adaptation to the respective application. Apart from a large variety of standard apertures special apertures can be realised. The aperture ensures an homogeneous light distribution in the beam and a sharp beam limitation.
Monitor signal:
In addition to the switching signal the fork light barriers of series F-LAS also provide an analog signal. "Monitoring" of the analog voltage allows a better evaluation of the switching signal. The output can also be used for measuring tasks.
These sensors mainly are characterised by their high switching frequency (typ. 25 kHz in case of line F-LAS-DC, and typ. 200 kHz in case of line F-LAS-DC-HS), the large variety of fork sizes and apertures, and their high switching accuracy.
The F-LAS laser fork light barriers are ideal for positioning tasks.
Fork light barriers with integrated amplifier
FIA Series
Fork light barriers of the FIA series primarily are chosen for high-precision trigger applications. They are frequently used in the stamping industry. Because of their compact and very sturdy design they are generally used in rough industry environments.
In the fork light barriers of the FIA series the complete electronic evaluation unit is integrated in the sensor housing. The visible light beam makes it considerably easier to adjust the light barrier. The switching state is indicated by a red/green LED.
In the FIA-A version the focus lies on high positioning accuracy, the temperature-compensated analog output provides a voltage that is proportional to the aperture's degree of covering. Various rectangular apertures are available.
The laser fork light-barriers of the FIA-L series primarily are used in the field of stamping for feed measurement and for the exact checking of small parts at high feed rates.
These sensors mainly are characterised by their high switching frequency (typ. 10 kHz), their compact design, and their high switching accuracy.
Frame light barriers
FLB Series
The frame light barriers of FLB Series are used for the measurement of smallest unguided parts.
The frame light barriers of FLB Series are extremely insensitive to outside light due to optical filtering and partly modulated operation. Still they guarantee safe measurement of parts with sizes starting from only 0.2 mm. An impact protection facility (aluminum baffle plates and rubber-metal vibration dampers) protects the optical unit of the frame light barrier against impacting parts.
With its compact design and with the remote control unit (in case of FLB-FR3) this type of frame light barrier is excellently suited for eject monitoring in a punching die, for example.
High sensitivity due to threshold correction:
By continuously monitoring the maximum value at the receiver a dynamic switching threshold correction compensates the effect of dirt accumulation. Increasing dirt accumulation therefore does not lead to change of sensitivity.
Functional principle:
The optoelectronic components of the transmitter and receiver units are arranged opposite to each other in the frame (in the sides in case of fork or split design). Both the transmitter and the receiver unit consist of a row of IR transmitter diodes or phototransistors, which form a homogeneous light curtain between the transmitter and receiver unit. If a measuring object now passes through this light curtain, part of the light band is covered, and less IR light thus impinges on the receiver unit. The signal generated by the phototransistors is then attenuated and differentiated proportional to the impinging quantity of light, and the differentiated signal is sent to a comparator pulse lengthening unit.
Parameterisable under Windows® (with FLB-CON8):
The products FLB-F, FLB-H, and FLB-V of the FLB Series can be connected to the electronic control unit FLB-CON8. The electronic control unit guarantees a stable voltage supply for the respective transmitter/receiver of the FLB Series.
The electronic control unit also amplifies and processes the analog signal of the receiver in a suitable manner. A micro-controller performs 12-bit analog/digital conversion of the analog signal, allowing recording and evaluation of the signal characteristics at the sensor. Furthermore the electronic control unit offers various options for intelligent transmitting power control (dirt accumulation compensation) at the sensor.
Parameters and measured values can be exchanged between the PC and the electronic control unit through either the RS232 interface or Ethernet interface. All the parameters can be stored in the non-volatile EEPROM of the electronic control unit through the interface.
The Windows® PC software FLB-TLB-CON8-Scope facilitates parameterisation, diagnostics, and adjustment of the sensor system (oscilloscope function). The software furthermore features the function of a data recorder that automatically records data and saves them on the PC's hard disk. Firmware updates can be easily performed through the RS232 interface even when the sensor system is installed.
Laser reflected light edge detectors
RED Series
With the RED series, reflected light edge detectors that are able to reliably detect edges starting from a height of 0.03mm are now available. The detectors of this series are characterised by their large detection distance and detection range, and by their high scan frequency of max. typical 100kHz. With comprehensive software algorithms the RED series also can be used for frequency measurements, for example of turbochargers or fans. RED detectors furthermore can be used to monitor the number of wires when cables are twisted in stranding machines.
Originally developed as copy counters for the printing industry, RED series detectors now have a multitude of other possible applications, e.g. welding seam detection, production of folded paper for air filters, production of corrugated aluminium pipes, or counting of caps that are arranged in stacks. A special detector version within the RED series also allows the detection of rising and falling edges.
Trigger light barriers
TLB Series
Trigger light barriers are mainly used in the field of metal stamping. The TLB series comprises light barriers with infrared light beam (IR) or visible light beam (VIS), in split shape as well as in fork shape (with or without compressed air supply). Characteristic for all light barriers of TLB Series is the external electronics: Pulsating light or constant light amplifier with digital output or analog output (voltage output and current output).
The light barriers (FKB, SLB) are primarily mounted at the stamping die bottom part, and are available with a so-called tool plug (TP, TPN, TPO). The connection from the tool plug to the amplifier is established by means of a connecting cable. Pulsating light and constant light amplifiers (TLB-CON) are usually connected to the interface box, which is mounted directly at the stamping machine (eccentric press). But, with part of amplifiers the electronics is already integrated in the tool plug housing.
SURFACE INSPECTION AND GLOSS MEASUREMENT
Do you need to perform gloss measurement, turbidity inspections or contrast or structure inspections? Then you have come to the right place! We provide various inline sensors for each measurement procedure:
The gloss detection sensors of out GLOSS series provide three different angle types (20°, 60° and 85°) depending on the degree of roughness of the surface to be measured.
Should you need to differentiate exactly between various interior components from the automobile sector, starting with a range of different-colored and structured leather and synthetic leathers, textiles and ultrasuedes, the COLOR GLOSS CONTRAST NIR sensors of the COAST series do just the job.
The haze plays an important role in ascertaining the surface quality of stainless steel and aluminum sheets. The sensors of the GLAST series can determine the quality of these metal surfaces with great precisions. Various graticules are available for these sensor types.
The SI-JET series allow you to keep the spraying procedure under control. Ranging from spray jets invisible to the eye to highly-dosed jets or targeted metering (individual droplets) delivered via a piezo nozzle, the SI Jet series is fitted with the matching sensors.
The SPECTRO-M series reveals the mid-wavelength infrared light range, permitting for example, the detection of thin oil layers or the ascertainment of the thickness of transparent, extremely thin films.
A further advantage: our sensors permit the highly-precise inline detection of your products even in challenging environments.
Color-gloss and structure sensors
COAST Series
The sensors of the COAST Series (COlor And STructure) are hybrid sensors that comprises two sensors that only are synchronised by the LED ring light but otherwise operate independently of each other. Both sensors can be connected to a PLC or to a PC.
One of the two sensors (color sensor) provides information about the color and gloss of the object to be inspected, while the other sensor (structure sensor) checks the structure of the surface.
Using forward and backward scattering of object surfaces in PARA mode:
Some object surfaces are very hard to differentiate if only backward scattering is used. If, however, forward scattering is used in addition, surfaces that have very similar colours but slightly different structures can be differentiated quite well. Light is directed onto the surface at an angle of -30° and +30° from the normal (vertical). Only one light source is active at a time, which allows independent evaluation of forward and backward scattering.
For each sensor (color sensor and structure sensor) a specific parameter set is saved both for backward and forward scattering, i.e. altogether four parameter sets are available:
1. Parameter set (IN0 = 0) ⇒ Color sensor: Forward reflection
2. Parameter set (IN0 = 0) ⇒ Structure sensor: Backward reflection
3. Parameter set (IN0 = 1) ⇒ Color sensor: Backward reflection
4. Parameter set (IN0 = 1) ⇒ Structure sensor: Forward reflection
Gloss and structure sensors
GLAST Series
Inline sensors of the GLAST series primarily are used for the inspection of highly reflecting surfaces (e.g. stainless steel panels, aluminum sheets, painted surfaces, plastic films) and transparent objects (films, glass plates, plexiglass plates).
A projection lens projects a line grid onto a line detector with the help of the object to be inspected, which functions as a more or less optimal mirror. Transparent objects are placed close to the line grid, which again is projected onto a line detector by a projection lens. In both cases the quality of the object determines the quality of the video signal at the line detector.
The reflective method operates at an angle of 30° (respectively 45°) each of the optical axes of the transmitter and receiver branch from the vertical, whereas in the through-beam method the object to be inspected stands vertically to the optical axis of the transmitter-receiver setup. In both cases the transmitter-receiver distance is approx. 135 mm.
Three different line grids are available in each case (0.5m/0.5mm, 1.0mm/1.0mm, and 2.0mm/2.0mm).
Gloss detection and mark detection sensors
GLOSS Series / RLS Series
Inline Gloss Meters (GLOSS Series)
In addition to the RLS-GD series another range of inline gloss meters is now available with the GLOSS series.
While the RLS-GD series is characterised by an extremely high insensitivity to extraneous light and focuses on a large detection range and thus on high optical integration (optical low-pass), the GLOSS series attaches importance to a small detection range (about half the size of the RLS-GD series). The GLOSS series thus has a higher local sensitivity (lower optical low-pass effect) and is considerably faster and more compact than the RLS-GD series.
Five different types are available with standard angles of 20°, 60° and 85°, as well as 45° and 75°, which predominantly are used in the paper industry. In addition to the analog outputs the GLOSS meters also have digital outputs that can be used for teaching.
Various standard measurement angles are available for the gloss sensors of GLOSS Series:
20°:
For high-gloss surfaces.
A 20° gloss sensor is used if gloss grades >70GU are to be determined. That is, if the gloss grade measured with a 60° gloss meter is >70GU, a 20° gloss sensor is used.
45°:
TAPPI standard (paper industry) for glossy surfaces.
60°:
For semi-gloss surfaces.
A 60° gloss sensor is used if gloss grades >10GU to <70GU are to be determined. This variant is an "all-rounder". The 60° gloss sensor is therefore standard for most applications.
75°:
TAPPI standard (paper industry) for matt surfaces.
85°:
For matt surfaces.
An 85° gloss sensor is used when gloss grades <10GU are to be determined. That is, if the gloss grade measured with a 60° gloss meter is <10GU, an 85° gloss sensor is used.
[GU = Gloss Unit]
Gloss detection sensors (RLS-GD Series)
Mark detection sensors (RLS-MD Series)
The sensors of RLS-GD series are used for online measurement of gloss degree. In the production of plastic sheets (design sheets, wall coverings, floor coverings, table coatings, foam sheets, and coated carrier materials for the furniture industry, automobile industry, fashion industry, or construction industry) and ceramic parts (ceramic tiles and plates for wall and floor) 100% quality inspection of the optically visible surface has become an ever more frequent requirement.
For this purpose the RLS-GD sensors feature non-contacting detection of the gloss degree. The simultaneous measurement of the object from two different directions (direct reflection and diffuse reflection) allows intensity-independent evaluation. The sensor can be taught to a certain surface, and up to 31 tolerance windows can be applied around the taught value. Measurement output is performed digitally by way of five outputs.
Line markings at different backgrounds should be detected without changing the settings of the sensor.
A suitable sensor for the mark detection (for example line markings at different backgrounds should be detected without changing the settings of the sensor) is the RLS-MD-2-FIO which has two fiber optic connectors, two white light sources, and two receivers.
Spray jet profile sensors
L-LAS-TB-...-AL-SC Series
The spray jet profile sensors of the L-LAS-TB-…-AL-SC series direct a laser light curtain through the spray jet. On the opposite side of the spray jet, the jet profile (rather the transmission through the spray jet) is recorded by a line detector and evaluated by suitable software. The Windows software L-LAS-SPRAY-CONTROL-Scope is available for convenient parametrization and monitoring.
A special housing means that the system can also be used in potentially explosive atmospheres.
Single-channel spray jet sensor
SPECTRO-1-FIO-JC
The transmitted light fiber optic of the SPECTRO-1-FIO-JC single-channel version of a spray-jet monitoring system suits it ideally to use both inside and outside potentially explosive atmospheres. In this process, a parallel directed white light beam (a collimation of the white light is achieved by a suitable attachment optic) is directed onto the spray jet and the light arriving on the side opposite the spray jet is focused by a receiving optical attachment onto the front surface of the receiver fiber optic. The jet attenuation compared to the state when the spray jet is not present serves as a measure for the density of the spray jet.
The evaluation is supported easily by the SPECTRO1-SPRAY-CONTROL-Scope parametrization and monitoring software.
Three-channel spray jet sensors
SI-JET Series
By means of three light barriers respectively three optical fibers integrated in a transmitter and receiver unit the SI-JET spray jet control systems check the density, symmetry, and cone angle of the spray jet. Choked or incorrectly set nozzles can thus be detected in time. Due to the integrated pressed air facility (at transmitter and receiver side of the fork) these systems are insensitive to dirt accumulation.
The comprehensive PC software SI-JET-Scope allows parameterisation of the system via Windows®.
Sensors for the mid-wavelength infrared light range (MIR)
SPECTRO-M Series
The sensors of the SPECTRO-M series are especially suited to measuring the thickness of thin oil or plastic layers on metal surfaces. They can measure layer thickness from 0.1µm. After the washing procedure of blanked and flexible parts it is necessary to check whether the cutting oil applied to the parts to facilitate the punching was removed entirely by the cleaning process. The test ink method using the properties of surface tension is often used to perform random checks; a component is usually taken as being clean once it presents a surface tension of 38mN/m and above.
Using the Windows® software in conjunction with the SPECTRO-M series, it is possible to measure the thickness in µm and the surface tension in mN/m. Sensors from the SPECTRO-M series can measure the thickness of thin transparent plastic films. The tension of stretch films can be checked; the thickness of a film can also be measured INLINE i.e. during its production.
SPECTRO-M-15-MIR Inline control of thin oil layers on metal:
The MIR measurement procedure deployed in the SPECTRO-M sensors was developed by Sensor Instruments in order to measure very thin organic layers on metal surfaces. As such, SPECTRO-M sensors are highly suited to the detection and inline control of thin oil films on metal. more...
DISTANCE MEASUREMENT AND POSITIONING
Line sensors are applied where precise positioning is required or where the dimensions of an object have to be determined with high accuracy (e.g. diameter of a wire).
Close range with distances starting from 20 mm, or wide range with distances of several metres, on steel, plastic, wood, paper, or textile surfaces – with the laser triangulation sensors of the L-LAS-LT series you will solve even the most difficult measurement tasks.
For through-beam operation with up to 2 m transmitter/receiver distance laser light curtains of the L-LAS-TB series are available up to a height of 100 mm. In combination with macro lenses these for example also allow the measurement of foil thicknesses with a resolution of approx. 100 nm.
We also offer an interesting range of optical-fibre distance sensors for application in Ɛx areas with distances of up to 20 mm and frequencies of up to 100 kHz.
Laser triangulation sensors
L-LAS-LT Series
The laser triangulation sensors of the L-LAS-LT series determine the distance or thickness of objects with highest accuracy (resolution starting from typ. 1 µm). By way of a master/slave sensor arrangement, two laser distance sensors are evaluated by a controller that is integrated in the master sensor. A special version is available for optically transparent objects (flat glass, foils, wafers).
The laser triangulation sensors of the L-LAS-LT-SL series are available in various variants with different reference distances (from 32.5 mm up to 600 mm) and in two types per variant: Either as type L-LAS-LT-SL-P with visible red laser spot (typ. Ø 0.3 mm) or as type L-LAS-LT-SL-L with visible red laser line (typ. 0.3 mm x 3 mm). Depending on the chosen variant the sensors have a measuring range from 21 mm up to 1000 mm.
Windows® PC software L-LAS-LT-Scope
The L-LAS-LT sensors can be easily parameterised with the Windows® user interface. With the help of the L-LAS-LT-Scope software the following settings can be made at the sensor:
Setting of laser power or light power and type of automatic power correction, polarity of digital outputs, different evaluation modes, start of the teach process by software button, setting of tolerance ranges for monitoring the measured value.
Furthermore, various numerical and graphical measured quantities can be visualized with the L-LAS-TB-Scope software. For example, the raw data of the CCD line sensor can be displayed graphically and numerically.
Reflected light line sensors
L-LAS-RL Series
The reflected light line sensors of the L-LAS-RL series are measuring systems that work in reflected-light mode. They can cover measuring ranges from 10 mm (at an operating distance of 33 mm with L-LAS-RL-10) up to a measuring range of 40 mm (at a reference distance of 100 mm with L-LAS-RL-40).
Windows® PC software L-LAS-RL-Scope
The L-LAS-RL sensors can be easily parameterised with the Windows® user interface. With the help of the L-LAS-RL-Scope the following settings can be made at the sensor:
Setting of light power and type of automatic power correction, polarity of digital outputs, different evaluation modes, start of the teach process by software button, setting of tolerance ranges for monitoring the measured value.
Furthermore, various numerical and graphical measured quantities can be visualized with the L-LAS-TB-Scope software. For example, the raw data of the CCD line sensor can be displayed graphically and numerically.
Laser transmitted light line sensors
L-LAS-TB Series
The L-LAS-TB sensors (transmitted-light series) offer various operating widths with a resolution of up to 1536 pixels (12288 subpixels). An analog output (voltage output and current output) informs about position and size of the object. Furthermore, a digital output is available that informs about quality and position of the object.
Windows® PC software L-LAS-TB-Scope
The L-LAS-TB sensors can be easily parameterised with the Windows® user interface. With the help of the L-LAS-TB-Scope software the following settings can be made at the sensor:
Setting of laser power or light power and type of automatic power correction, polarity of digital outputs, different evaluation modes, start of the teach process by software button, setting of tolerance ranges for monitoring the measured value.
Furthermore, various numerical and graphical measured quantities can be visualized with the L-LAS-TB-Scope software. For example, the raw data of the CCD line sensor can be displayed graphically and numerically.
Line camera sensors
L-LAS-CAM Series
The line cameras of the L-LAS-CAM series are measurement systems that can be configured to exactly match the desired application. In addition to the electronic evaluation unit various precision lenses, filters, etc. also are available. It is furthermore possible to connect an external light unit (LU-LED-...-VIS, LU-LED-...-VIS-DIF). These measurement systems are ideal for positioning with micrometer accuracy.
Windows® PC software L-LAS-CAM-Scope
The L-LAS-CAM sensors can be easily parameterised with the Windows® user interface. With the help of the L-LAS-CAM-Scope software the following settings can be made at the sensor:
Setting of light power and type of automatic power correction, polarity of digital outputs, different evaluation modes, start of the teach process by software button, setting of tolerance ranges for monitoring the measured value.
Furthermore, various numerical and graphical measured quantities can be visualized with the L-LAS-TB-Scope software. For example, the raw data of the CCD line sensor can be displayed graphically and numerically.
DYNAMIC DISTANCE MEASUREMENT AND DYNAMIC POSITIONING
With many applications it is essential to determine distances, e.g. the distance between two objects (gap size measurement) during a movement. The sensors of the A-LAS series or the SPECTRO-1-CONLAS series and the SPECTRO-2-CONLAS series perform very good services and can provide scan frequencies of up to 175 kHz. The measurement ranges are determined by the light spot size. Spot sizes from 0.1mm to 100mm are available.
Fibre optics cross-section converters can be used in potentially explosive atmospheres. The longitudinal axis of the right-angled cross-section determines the size of the measurement range. The SPECTRO-1-FIO and SPECTRO-2-FIO sensors are two quick versions for potentially explosive atmospheres with scanning frequencies up to 175 kHz or 130 kHz.
Laser analog light barriers
A-LAS Series
Laser analog light barriers and electronic control units
With the laser analog light barriers of A-LAS Series parallel laser light with homogeneous light distribution in round or rectangular cross-section is used for measuring, positioning, and detection of objects starting from a size of 0.01 mm.
The A-LAS light barriers work according to the following measuring principle: The laser light beam that is emitted by a high-precision optical unit (aspherical surface made of glass) allows the detection of smallest objects (e.g. threads) even in case of a large transmitter/receiver distance (distances up to 100 m, depending on model and aperture).
The use of high-precision apertures in the transmitters ensures optimum adaptation to the respective application. The aperture guarantees a homogeneous light distribution on the beam and a sharp beam limitation.
Apart from a large variety of standard apertures special apertures can also be realised.
Modulatable laser analog light barriers
A-LAS-N Series
In addition to the A-LAS series, we now also provide the extended A-LAS-N series. In addition to continual current feed (DC) of the laser light source, the N (Neo) version also provides the feature of modulation (AC), i.e. an alternating current feed to the laser diode, through which any present or interfering extraneous light can be compensated.
As such, it is possible to perform extremely precise measurements, even under extraneous light influence. We are currently planning to extend the range of A-LAS-N types available to ensure that at least the most common representatives of the A-LAS family are also available as an A-LAS-N version.
A-LAS-N series sensors can be operated very easily and highly efficiently using the SPECTRO-1-CONLAS and SPECTRO-2-CONLAS evaluation units. The SPECTRO-1-CONLAS system is a single channel system, i.e. an A-LAS-N laser light barrier can be connected for each evaluation unit, whilst a SPECTRO-2-CONLAS is able to actuate two A-LAS-N sensors.
Single-channel evaluation system
SPECTRO-1-CONLAS
The SPECTRO-1-CONLAS single channel evaluation unit can be used to connect an A-LAS-N laser light barrier.
The parametrization of the evaluation unit is performed using comprehensive SPECTRO1scope software in Windows® on the PC. In order to facilitate the interpretation of the measurement signals, an oscilloscope tool was added to the software to display the signals on the Windows® interface in real time. A diverse range of digital-series converters permits data exchange via USB Ethernet and RS232. Two digital outputs (0V/+24V), two digital inputs (0V/+24V) for external synchronization and an analog output (0V ... +10V switchable to 4mA ... 20mA) are also available.
Two-channel evaluation system
SPECTRO-2-CONLAS
Two A-LAS-N laser sensors can be connected using the SPECTRO-2-CONLAS two-channel evaluation system.
The evaluation unit is parametrized on the PC using the comprehensive SPECTRO2-Scope software in Windows®. The Scope software tool permits the storage and analysis of signals in real time. Both the analog output and the digital input and output signals are graphically displayed on the monitor. A diverse range of digital-series converters permits data exchange via USB Ethernet and RS232. Two digital outputs (0V/+24V), two digital inputs for external synchronization and an analog output (0V ... +10V switchable to 4mA ... 20mA) are also available.
