What is Thermocouples? Standard Thermocouples

Temperature Measurement

Thermocouple A thermocouple consists of a pair of different metal or alloys joined together at both ends. One end, measuring junction, is placed where temperature is to be measured. The two conductors extend out of the measurement area to the reference junction. An electromotive force (emp or mV) is produced which is function of temperature …

How to Calibrate Temperature Switch?

Calibration

What is a temperature switch? Temperature switches, commonly referred to as thermal switches, are used to open and close switch contacts (thermostat). Depending on the input temperature, the switching status of the temperature switch changes. In order to safeguard against overheating or overcooling, this feature is employed. In general, thermal switches are used to control …
