A Thermocouple is a sensor used to measure temperature. Thermocouples are made from two-wire made from different metals. These wires are welded together at one end to form a tip called a junction. The junction is where the temperature is measured. When the junction sees a change in temperature, a milli-voltage is created. This signal is then calculated by a temperature controller to give an accurate temperature reading.
The most common is type K and J
Whereas a J Type thermocouple is made up of iron and constantan, K type thermocouples are composed of a nickel/chromium alloy (chromel) and a nickel/aluminium alloy (alumel) which gives them much better protection against oxidation and acidity than the iron limbs of the Type J.
Easy assembly and convenient for replacement;
