Thermocouple - What is it?
Knowledge Base

Automation Media's recommended most important key terminologies you need to know if you work in Automation, Controls, Brilliant Manufacturing, Operational & Industrial Intelligence or IoT etc. ; regardless of any vendor(s) you are dealing (Allen Bradley, GE Fanuc, Siemens, Modicon, Mitsubishi, Omron, Automation Direct etc).


  • A Thermocouple is a ThermoElectric Device used to measure temperatures accurately, especially ones consisting of two dissimilar metals joined so that a potential difference generated between the contact points measures the temperature.

  • A Thermocouple is a Sensor for Measuring Temperature.

  • It consists of two dissimilar metals, joined together at one end.

  • When the junction of the two metals is heated or cooled a voltage is produced that can be correlated back to the temperature.

  • The thermocouple alloys are commonly available as wire.

  • It is low cost, wide operating range and ruggedness.

  • It consists of two dissimilar metals joined together, making a continuous loop. When one junction has a different temperature from the other an electromotive force (voltage) occurs.

  • There are several types of thermocouples, constructed from different metals and with differing temperature ranges and accuracies.
