Thermocouple - What is it? Knowledge Base
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.
