They are as follows:1) Seebeck effect: The Seebeck effect states that when two different or unlike metals are joined together at two junctions, an electromotive force (emf) is generated at the two junctions. The most common types (calibrations) are J, K, T, and E. Although the thermocouple calibration dictates the temperature range, the maximum range is also limited by the diameter of the thermocouple wire. Due to the simplicity of the design, simply two wires joined together, thermocouples are suitable in processes where shock and vibration are present.
