In the railway transport sector, the precise monitoring of the fill level of liquids and bulk goods is exceptionally important for ensuring smooth and safe operations. Over recent years, capacitive level switches have established themselves as an innovative solution for meeting these requirements.
Monitoring the filling level in rail vehicles is essential for various areas of use such as fuel or coolant tanks, brake and hydraulic systems, and wastewater and sewage tanks. Accurate level measurement not only guarantees optimum system operations, but also ensures the safety and efficiency of rail transport. Capacitive level switches use the principle of the change in capacitance between a probe and the surrounding medium to measure filling levels. Electrical capacitance occurs when an electrical field forms between the probe and the medium. This capacitance changes depending on the filling level as the medium’s dielectric constant changes. This change is acquired by the level switch and converted into an electrical signal.
Short-circuit and reverse polarity protection provides additional safety for the JUMO ZELOS C01 LS. An antivalent electrical circuit enables the detection of line faults such as a cable break. A firmware update profile allows the sensor to be updated while installed so that plant downtime is minimized. PNP, NPN, push-pull, and IO-Link are available as output signals. A 360° illuminated status display enables easy recognition of the sensor status according to NAMUR and VDI/VDE.
The JUMO ZELOS C01 LS capacitive level switch identifies the level of liquids and solids. This device can also be used in pressurized tanks or in pipes. During use, it showcases its advantages in applications with requirements for overflow and dry-run protection or for media detection. JUMO ZELOS C01 LS can be used in liquids or bulk solids with temperatures between -40 and +200 °C. Thanks to the auto-calibration function, point level measurement offers both reliability and long-term stability. In addition, after configuration, the 2 switching outputs can automatically distinguish reliably between 2 measured media. Even adhesions do not present a problem for the reliable sensor. The product design contributes to miniaturization in sensor technology so that compact systems can be implemented. Mounting is easily achieved with a standard torque wrench. Since the seal to the medium goes through the sensor tip, no separate seal is required, thereby eliminating the possibility of a mix-up.
