A Quick Guide On Different Types On Thermocouples

A thermocouple is a common type of temperature sensing device. They are very cheap, easy to use, and can determine a wide range of temperatures. Its working principle is the production of a small voltage at the junction joining two dissimilar heated metals. Accurate measurement of this voltage will give you the temperature of the surrounding. They are mainly used as governing sensors in various heating and cooling devices.

Different thermocouple types which are widely used are type-B, E, J, K, N, R, S, and T. Three things to be considered while choosing a thermocouple are its insulation, probe construction, and type. These are the three main features which will determine the accuracy and sensitivity of the reading given by a thermocouple. Thermocouple types with lower sensitivity range will have a lower resolution.

The K-type thermocouple is the most commonly used thermocouple. It can be used with a lot of different kinds of probes. Its range is from negative 200°C to positive 1200°C. The metals used
