What is the temperature of the bimetallic thermometer compensation?

Bimetallic thermometer is mainly used in chemical and petrochemical industry, power engineering, food, machinery manufacturing and general factory construction. Use after a period of time need for calibration, the calibration will involve the temperature compensation. So what temperature compensation? In the inherent deviation due to temperature measuring device in the temperature measurement, the need for temperature measurement calibration. This correction is temperature compensation. So the bimetallic thermometer temperature compensation is when the bimetallic thermometer calibration, there will be a error value, and standard thermometer calibration again after there will be a calibration value, the actual temperature and normal temperature is called a difference between bimetallic thermometer temperature compensation. Later in the use of the bimetallic temperature timing will be considering the temperature compensation, according to the calibration value to add and subtract the actual temperature, so the final reading is correct.
