Thermocouple Signal Conditioning for Long Wire Runs Application Guide

This document discusses the challenges of using long thermocouple wire runs in industrial environments, including EMI susceptibility and signal degradation, and presents a component-based solution using a signal conditioner and thermocouple terminal block. It compares direct thermocouple connection to a PLC with a solution that converts the thermocouple signal to a 4-20mA current loop for improved accuracy, cost-effectiveness, and noise immunity.
