Circuit provides cold-junction compensation

https://www.electronics-lab.com/circuit-provides-cold-junction-compensation/

Mark Maddox @ edn.com has a design idea on cold-junction compensation using AD7708. The accuracy of any circuit or system that uses a thermocouple to determine the temperature of a process is limited by the accuracy of the method used to perform cold-junction compensation. In a thermocouple measurement, two wires of dissimilar metal join together […]
