Working principle
RTD measure temperature according to the characteristic of metal wire changes electrical resistance along with temperature, the thermoelement of RTD is made by metal wire be wound on the surface of insulation skeleton. If there is temperature gradient in the measured medium, the measured temperature is an average temperature of element in the range of the medium zone.
