How RTD Measuring the Temperature
Measuring temperature with RTD / Resistance thermometer The RTD resistance will change with respect to the temperature. So temperature will be measured by using the RTD resistance. The simplest way to...

How a 4 Wire RTD Works ?
4 Wire RTD Principle The most accurate lead wire configuration is the “true” 4-wire configuration. In a true 4- wire configuration, the resistance of the lead wires does not contribute...
Resistance Temperature Detectors Working Principle
Resistance Temperature Detectors (RTD) Working Principle Thermo-resistive Temperature Measuring Devices A change in temperature causes the electrical resistance of a material to change. The resistance change is measured to infer...
Thermocouple Working Principle
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
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)...
