The combination of the bayonet nut, spring and the corresponding bayonet adapter can provide higher pressure from the temperature sensor with the bayonet in the measured point or can adjust any change in the distance between the nut and the point measured during the measurement. The maximum operating temperature range of the sensor is between -50 and 350 ° C (400 ° C for a short time). The range of each variant is reduced with one type of temperature sensing element and the power cable. The temperature sensors meet the protection standards IP 50 to IP 67 according to standard EN 60529, depending on the variant of the input cable.
