Understanding the Importance of Thermocouples and How They ...

Apr 29, 2017· A thermocouple is a sensor used for measuring temperature. It comprises of two dissimilar metal wires, which are connected at one end and joined to a thermocouple-thermometer or another thermocouple-capable device at the other end. When thermocouples are properly configured, they can provide temperature measurements over a wide temperature range.

Temperature Measurement With Thermocouple, RTD ...

The RTD also experiences more thermal shunting ( The act of altering the measurement temperature by inserting a measurement transducer). But the biggest difference between them is their measurement range. While most RTDs are limited when it comes to high temperatures (max 538°C), Thermocouples can be used to measure …

Thermocouple Cold (Reference) Junction Compensation

Sep 19, 2017· Thermocouples are very common temperature sensors in process plants. Thermocouples have few benefits that makes them widely used. They can be used to measure very high temperatures, much higher than with RTDs (Resistance temperature detector). The thermocouple is also a very robust sensor, so it does not break easily.
