The maximum temperature range of the sensors is between - 50 and 350 ° C (400 ° C in the short term). The range of individual design variations is narrowed down to the type of temperature sensing element and power cable. The sensors meet the protection level from IP 50 to IP 67 according to EN 60529, depending on the type of input cable. The sensors are designed to operate in a non-aggressive environment. The method of use should be chosen based on the temperature and chemical resistance of the housing and input cable.
