Full details of thermocouple types , range and wire color coding
Thermocouple Types & Ranges Thermocouples are temperature sensors that work on the principle of the Seebeck effect, which generates a voltage difference between two dissimilar metals when they are exposed to a temperature gradient. Different types of thermocouples are available, each with unique material combinations that allow them to measure temperatures within different ranges. Additionally, each type of thermocouple has a distinct color coding scheme for its wires to ensure proper connection and accurate temperature readings. Here are the full details of the most common thermocouple types, their ranges, and wire color coding details: 1. Type J thermocouple: This type of thermocouple uses iron and constantan wires and has a temperature range of -210°C to 1200°C. The positive wire is colored white, and the negative wire is colored red. 2. Type K thermocouple: This type of thermocouple uses chromel and alumel wires and has a temperature range of -270°C to 1372°C. The positi...
