What is the principle of measuring motor temperature with thermal resistance probe?
Thermal resistance is to measure the temperature by using the characteristics that the resistance of a substance changes with temperature. The heated part of the thermistor (temperature sensing element) is made of thin metal wires which are evenly and doubly wound on the skeleton made of insulating materials. When there is a temperature gradient in the measured medium, the measured temperature is the average temperature of the medium layer within the range of the temperature sensing element. Now the thermocouple probe has more functions.
