Thermal resistance is to measure the temperature by using the characteristic that the resistance of material changes with the change of temperature. The heating part of the thermal resistance (temperature sensing element) is made of metal wires evenly double wound on the framework made of insulating materials. When there is a temperature gradient in the measured medium, the measured temperature is the average temperature in the medium layer within the range of the temperature sensing element.
The assembled thermal resistance is mainly composed of junction box, protective tube, terminal block, insulating sleeve and temperature sensing element, and is equipped with various installation and fixing devices.
WZP type platinum thermistor.
