Description:

Micropower Thermocouple Cold Junction Compensator

Features

* s 80µA Supply Current s 4V to 36V Operation s 0.5°C Initial Accuracy (A Version) s Compatible with Standard Thermocouples (E, J, K, R, S, T) s Auxiliary 10mV/°C Output s Available in 8-Lead PDIP and SO Packages U APPLICATIO S s Thermocouple Cold Junction Compensator s Centigrade Thermometer s Temper

Applications

* The idea is basically to add a temperature dependent voltage to VS such that the voltage sum is the same as if the T2 junction were at a constant 0°C instead of at room temperature. This voltage source is called a cold junction compensator. Its output is designed to be 0V at 0°C and have a slope eq
