What Is a Thermocouple? A Simple Guide to How Temperature Measurement Works
Many industrial processes require precise temperature measurements. It can be plastic production, metalworking, or industrial heating, but the precise temperature can make a significant difference. This is where a Thermocouple comes into the picture. In case you have heard the word previously but are not quite sure of what it does, then you are at the right place. This post will describe what a thermocouple is, how it operates, and why it is so popular in various industries. Understanding a Thermocouple A Thermocouple is a temperature sensor which is made up of two dissimilar metal wires that are connected at one end. As the joined end undergoes a temperature change, it produces a small electrical voltage. This voltage is then measured and converted into a temperature reading. It is easy to understand why thermocouples are so popular. They are dependable, economical and can measure a broad spectrum of temperatures. Therefore, they are usually present in industrial machines, furnaces, ...
