Everything You Need To Know About Thermocouples | RS ...

As noted above, a thermocouple is a sensor tool that’s principally designed to measure the unknown temperatures of various physical bodies, components or substances. Crucially, a thermocouple is made up of at least two wires of different metals that, when joined together to form a circuit, create two separate electrical junctions. One junction is located where an unknown temperature needs to be measured …

What is difference between thermocouple and pyrometers ...

A thermocouple is a device with a junction of dissimilar metals that actually produces an thermoelectrical current which can be calibrated and measured a temperature. The thermocouple accuracy can be affected by the connection of the copper leads to the device, so this cold junction must be compensated for. The thermocouple can be made from several combinations of dissimilar metals …

A Basic Guide to Thermocouple Measurements

Thermocouples are temperature measurement sensors that generate a voltage that changes over temperature. Thermocouples are constructed from two wire leads made from different metals. The wire leads are welded together to create a junction. As the temperature changes from the junction to the ends of the wire leads, a voltage develops across the junction.
