WZ series of assembing type industrial thermal resistances are designed and produced according to IEC standard. They normally work as a temperature sensor. They are used together with temperature displays and controls to detect and control the temperature of gas, liquid or solid surface. The working range is from -200ºC to 800ºC. A WZ thermal resistance contains temperature sensor, fixing parts and junction box. | ![]() |
