TG 75, -50 °C to 350 °C (400 °C short-term)

These resistance temperature sensors TG 75 are designed to measure the surface temperature of solid substances.

The construction of the sensor enables fixed connection to the measured surface by using two screws placed into the holes in the sensor case. The structure of the sensors also enables fast response to the changes in temperature when silicone grease is applied between the measured surface and the sensor. On the place of case transition to cable, there is a spring that protects the cable from mechanical damage. Maximum temperature range of sensor use is -50 °C to 350 °C (400 °C for a short period). The range for each design variant is reduced with a type of the temperature sensing element and the supply cable. The temperature sensors meet ingress protection from IP 50 to IP 67 according to the CSN EN 60 529 standard, depending on the supply cable variant.

The temperature sensors are intended for operation in chemically non-aggressive environment. By using temperature sensor is recommended to ensure striping sensor from the influence of ambient temperature and thus reduce the error method due to the impact of differences between the measured temperature ambient temperature.
