Thermocouple Basics Guide

This document provides a comprehensive overview of thermocouples, including their operating principle (Seebeck effect), types (B, R, S, N, K, E, J, T), selection criteria based on temperature range and environment, and key usage considerations such as compensation lead wires, junction types (grounded, non-grounded, exposed), calibration methods (fixed point and comparison), and service life. It also covers troubleshooting, measurement methods (cold junction and reference junction compensation), and the importance of proper installation and calibration for accurate temperature sensing.
