JUMO Temperature Solutions

Temperature is one of the most commonly measured physical measurands throughout the world.

During the mid-1960s, the manufacturing of high-quality and accurate temperature probes offering long-term stability began to mature into one of JUMO's core fields of expertise. Ever since then JUMO has been producing RTD temperature probes and thermocouples of outstanding quality. We are now one of the world's leading manufacturers

in this field.

Temperature Measurement

The application spectrum ranges from measurements in building technology to the acquisition of temperatures up to 600 °C in industrial furnace processes (e.g. foundry technology). Because so many different application areas are involved, the thermal and mechanical requirements for temperature probes vary widely and have changed over the years. Through different design types, materials, and components such as protection fittings the probes can be optimally adjusted to the respective measuring task. As a result, extreme vibrations, atmospheres containing steam and which are under pressure, as well as aggressive media are controllable.

Approvals and standard requirements

ATEX, EAC Ex, metrological registration, PL, SIL, DNV GL, DIN EN 14597, AMS2750, CQI-9

Thermocouples

Thermocouples are mainly used to measure higher temperatures. Different thermocouples are used depending on the requirements. These are regulated in several standards including German (DIN 43710 – has now been discontinued), European (DIN EN 60584), and American (ANSI MC96.1 or ASTM E230) ones. The special requirements of the respective application (e.g. operating temperature, existing atmosphere, prevailing pressure, etc.) are considered through the construction selection and the materials. Here, thermocouples can be complemented by additional JUMO products (e.g. through transmitters for transfer of the measuring signals).

Hygienic Thermowells

The hygienic thermowells have been designed for use with temperature probes in the food and pharmaceutical industry.

All common process connections within the industry such as clamp, VARIVENT®, aseptic screw connection according to DIN 11864-1, and the CIP-compliant conical seal are available as a thermowell. The standard material is stainless steel 316L with surface finish Ra ≤ 0.8 μm. A surface finish of Ra ≤ 0.4 μm is also available as an optional extra.

This wide variety creates a versatile system suitable for any application.

The use of hygienic thermowells hygienically seals the process. Easy replacement of the sensor is guaranteed without process interruption. This way, maintenance and repair costs can be reduced.

JUMO Wtrans receiver

Operation and configuration can be performed via the keypad in conjunction with a two-line LCD display or with an intuitively operable setup program for even greater convenience. This way, parameters such as measured value scaling, offset, alarms, and limit values can be separately set for each channel. For this purpose, a connector is provided on the front for a PC interface with a TTL/RS232 or USB/TTL converter for connecting the receiver and the PC.
