product manual:

       Thermal resistance temperature sensor is a sensor thermometer that uses the principle that the resistance value of a conductor or semiconductor changes with temperature.

       Thermal resistance temperature sensors are divided into two categories: metal thermal resistance and semiconductor thermistor. Thermal resistance is widely used to measure the temperature in the range of -200~+850°C. In a few cases, the low temperature can be measured to 1K, and the high temperature can reach 1000°C.

       The thermal resistance sensor is composed of thermal resistance, connecting wires and display instruments. The thermal resistance can also be connected to a temperature transmitter to convert the temperature into a standard current signal output.

       The material used to manufacture the thermal resistance should have as large and stable temperature coefficient of resistance and resistivity as possible, the output is linear, the physical and chemical properties are stable, and the complex linearity is good. The commonly used thermal resistances include platinum thermal resistance and copper thermal resistance.
