Abstract

This paper presents a new design of a very low cost two-channel type K thermocouple interface circuit for micro-controllers. This interface circuit targets accurate temperature measurements for nuclear research instrumentation from 0 up to 250 degree Celsius with 1 degree resolution. The usage of the computational capabilities of a micro-controller is proposed to make an adaptive self calibration for the designed interface circuit. Also, these computational capabilities are used to solve the two major problems associated with thermocouples, namely the thermocouple non-linearity problems and the offset errors resulting from the thermocouple reference junctions.
