Compact Resistance Thermometer TP 50 Hengesbach

Hengesbach is a company from Deutschland. For more than 50 years Hengesbach develops, manufactures and distributes innovative measuring technology for applications in production processes where functionality, reliability and accuracy of the instruments are of highest priority even under extreme process conditions.

Hengesbach offers a comprehensive equipment portfolio for temperature measuring. Apart from mechanical thermometers, we mainly offer industrially optimised resistance thermometers (PT100 sensors, thermo-elements, etc.) and temperature transmitters with different electronic interfaces.

Compact Resistance Thermometer TP 50

The resistance thermometer TP 50 Hengesbach in compact design is optimal suited to measure the temperature of fluids. It comes with various hygienic process connections. The stainless steel vibration proof design (protection class IP66 and IP67) is ideally suited for applications in critical environment and sophisticated and challenging process conditions. The fitted transmitter is programmable via the round plug M 12×1 and enables with this universal use.
