ABSTRACT:
A cold junction compensation system for a temperature measurement device having a processing circuit is disclosed. The cold junction compensation system includes a cold junction temperature sensor arranged in signal communication with the processing circuit, a thermal coupler in thermal communication with the cold junction temperature sensor, and first and second contacts each in thermal communication with the thermal coupler and in electrical isolation with each other, each contact arranged for signal communication with the processing circuit and arranged for signal communication with a hot junction temperature sensor. A signal from the hot junction temperature sensor is communicated to the processing circuit via the first and second contacts, the cold junction temperature sensor senses the cold junction temperature at the first and second contacts via the thermal coupler, and a signal representative of the cold junction temperature is communicated to the processing circuit for enabling a cold junction compensation calculation.
