3B37 - Analog Devices

3B37 Thermocouple Input

The 3B37 is a single-channel signal conditioning module that interfaces, amplifies and filters input voltages from a J, K, T, E, R, S or B-type thermocouple and provides isolated simultaneous voltage and current outputs linear with input voltage. High accuracy internal cold junction compensation and a predictable upscale open circuit indication provide a com.
