Thermocouple temperature sensor error measurement way

Each thermocouple sensor error of the need to measure it, except, of course, also can't thermocouple temperature sensor, the error of thermocouple sensor to measure temperature, and integrator measurement at the same time, the temperature of the thermocouple sensor error and the error of the integrator additive is the result of the need; And combined instrument, can the thermocouple temperature sensor measurement alone.

temperature thermocouple sensors separately measured the specific method is:

thermocouple sensor under constant temperature environment, the determination of thermocouple sensor under different temperature showed that the error between the temperature and accurate temperature. Need to know is, in addition to the error of measuring temperature thermocouple sensors alone, also check with part of the thermocouple sensor error, is the thermocouple sensor and integrator measurement at the same time, so you need according to different design principle of the integrator with the corresponding measurement method, two methods of measuring error of the measured combination can get the correct temperature thermocouple sensor error.
