About Resistance thermometers

Resistance thermometers measure process temperature in vessels and pipework and screw straight into the process with a G 1/2 male thread. They suit liquid and gaseous media under moderate mechanical load and normal chemical stress. The group holds 26 versions, either with a terminal block or with a built-in transmitter.

What matters when choosing

• Output signal and transmitter: the terminal block version passes the Pt resistance signal on directly, while the transmitter version gives 4 - 20 mA and can be wired to the control system without a separate converter.
• Insertion length follows pipe diameter and the immersion depth you want. Lengths of 50, 100, 160, 250 and 400 mm are among those available.
• Measuring span: the TR10-C series is rated -30 to 300 °C, the compact TR36 series -30 to 150 °C.
• Housing in CrNi steel 1.4571 or aluminium. The stainless housing belongs in wash-down and corrosive areas, aluminium is enough in dry machine surroundings.
• Protection IP 65 or IP 67. IP 67 is the choice where temporary flooding or intensive cleaning has to be expected.

Typical applications

• Temperature monitoring in pipework and process vessels
• Flow and return temperature in heating and cooling circuits
• Measuring points on heat exchangers and storage tanks
• Control loops feeding a 4 - 20 mA signal to a PLC or process control system
• Monitoring coolant and hydraulic circuits on machine tools

Housings are CrNi steel 1.4571 or aluminium in IP 65 or IP 67, and the process connection is G 1/2 male throughout. Manufacturing takes place in Poland and Germany.
