What is a Thermocouple and How Does it Work? – A GalcoTV Tech Tip


A thermocouple is a thermoelectric device for measuring temperature. The basic thermocouple consists of two wires, made of different metals, connected at one end that produces a voltage between the junction in proportion to the temperature that the wires are exposed to.

There are many types of thermocouples, each with its own unique characteristics in terms of temperature range, durability, vibration resistance, chemical resistance, and application compatibility. Type J, K, T, & E are “Base Metal” thermocouples are the most common. Type R, S, and B thermocouples are “Noble Metal” thermocouples, which are used in high temperature applications.

Thermocouples are manufactured in a variety of styles, such as thermocouple probes, thermocouple probes with connectors, transition joint thermocouple probes, infrared thermocouples, bare wire thermocouple or even just thermocouple wire.
