Thermocouples

A Thermocouple is a device which measures temperature. It is made up of two wires of different metals that, when joined together, create an electrical junction. When the temperature changes at this junction it creates a voltage which can be interpreted to read the temperature. This is also known as the Seebeck effect. You can read more about these tools in our bespoke Thermocouples Guide

Types of thermocouples

There are various types of thermocouples, each with different characteristics, such as temperature range and their robustness. Each thermocouple is defined by a letter such as “K”. Common types include J, K, L and T. The letters refer to the type of materials used and therefore the temperature they are usable at. For example, type J is iron and copper-nickel and is useable from around 0°C to 816°C, depending on other characteristics. Some thermocouples come with an additional sheath which provides protection to prolong its life.

Thermocouples are ideal tools for temperature measurement as they are robust yet affordable solutions.
