ABSTRACT:
An apparatus and system is presented for partially compensating the cold junction of a thermocouple system using low cost semi-compensated conductors of system components accommodating various thermocouple types. The thermocouple system, comprises a thermocouple portion comprising two thermocouple types, each type composed of two different thermoelectric materials joined to form a hot junction, a semi-compensation portion comprising two substantially similar conductor pairs, each composed of a different material, wherein one conductor of each pair is composed of a material different than the thermoelectric materials of the respective thermocouple type of the thermocouple portion. The thermocouple system further comprises a cold junction compensation portion comprising at least two cold junction conductors composed of the same material, and wherein at least one conductor is composed of a different material than the conductor pairs of the semi-compensation portion, and a cold junction formed by the connection of the semi-compensation portion conductor pairs and the cold junction conductors. The conductors of the semi-compensation portion also engage with the thermoelectric materials of the thermocouple portion to provide an electrical interconnection therebetween, and to provide a partial compensation to the EMF developed at the cold junction of the respective thermocouple.
