Kompensacja temperatury termopary

Kompensacja temperatury termopary
Since the materials of thermocouples are generally relatively precious (especially when precious metals are used), and the distance between the temperature measurement point and the instrument is very far, in order to save thermocouple materials and reduce costs, a compensation wire is usually used to extend the cold end (free end) of the thermocouple to the control room where the temperature is relatively stable, and connect it to the instrument terminal{{0}} It must be pointed out that the role of the thermocouple compensation wire is only to extend the hot electrode, so that the cold end of the thermocouple moves to the instrument terminal in the control room. It itself cannot eliminate the impact of the cold end temperature change on the temperature measurement, and it does not play a compensatory role. Therefore, other modification measures are required to compensate for the impact on temperature measurement when Temperatura zimnej końcowej t 0 ≠ 0 stopnia . podczas korzystania z przewodów kompensacji termopary, konieczne jest zwrócenie uwagi na dopasowanie modeli, polaryzm nie może być niepoprawnie podłączony, a różnicę temperatury między drutem kompensacyjnym a końcem połączenia termopar
