TG 40, -50 °C to 350 °C (400 °C short-term)

These right-angle resistance temperature sensors with a bayonet and thermocouple temperature sensors with a bayonet, are designed to measure temperature of solid substances, however, they may be used also to measure temperature of liquid and gaseous substances.

Due to temperature sensor design, the cable is led out at right angle to measuring part of the sensor. To fasten the temperature sensor into a point to be measured, the bayonet head that is screwed onto a spring is used. Combination of the bayonet nut, the spring and the corresponding bayonet adapter can provide higher pressure of the right-angle temperature sensor with the bayonet into the measured point. Maximum temperature range of right-angle temperature sensor use is -50 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 EN 60529 standard, as amended, depending on the lead-in cable variant.

The right-angle temperature sensors with a bayonet mount are intended for operation in chemically non-aggressive environment.
