Thermocouple Working Principle

S Bharadwaj Reddy
THERMOCOUPLES A thermocouple is made up of two dissimilar metals, joined together at one end, that produce a voltage (expressed in millivolts) with a change in temperature. The junction of...

Basics of Thermocouples and RTD

S Bharadwaj Reddy
Thermocouples What are Thermocouples? Thermocouples are temperature sensors. They operate under the principle that the junction of two dissimilar metals (forming a closed circuit) produces a measurable voltage (electromotive force)...
