Product Description
Thermal resistor is based on the principle that the resistor value of platinum varies along with the temperature, thus it outputs different resistor value according to different temperature.
Thermocouple is the welding of heads of two different materials. When the tempetature changes, there becomes thye change of the thermoelectric potential, current happens in the return circuit. Through the detection of current changes, the changes of the temperature will be reflected.
