The temperature probe is generally a thermocouple or RTD, thermocouple temperature voltage changes, the thermal resistance temperature resistance change, that is good.

Temperature sensor calibration and calibration
Calibrated temperature sensor (or temperature measuring system ,temperature probe calibration ) methods can be divided into two categories, one is comparing with a standard temperature sensor, KELI weighing sensor that is in accordance with the International Temperature Scale of 1990 (IPTS) CIPM by comparing 1968; the second is temperature sensor temperature measuring means associated with a standard calibration has been compared.
Temperature sensor reference point method is to use a sealed container that has the reference material, MKCELLS load cells sensitive element of the temperature sensor to be calibrated on the center position of the sleeve extending in one container,automated fuel management system and then heated to temperatures in excess of the reference substance melting point, until the material completely melted, temperature sensor then cooled, after reaching the freezing point, as long as the presence of liquid and solid (about a few minutes) while the temperature is stabilized, and can maintain a predetermined constant value.
