Thermocouple Cold End Compensation System with Programmable Function

Abstract

The thermocouple is the most commonly temperature sensor used in the measurement technique. But because of the fluctuation of the ambient temperature, the cold temperature is difficult to hold invariableness. This paper proposes an improved method. There are all kinds of thermocouple compensation tables in the system. And according to the actual need, we can select the corresponding table to make the cold junction compensation. This system meets the needs of various types of thermocouples.
