What is a Thermocouple?
A thermocouple is a transducer that converts thermal energy into electrical energy by joining wires of dissimilar metals to create a junction. Temperature changes at this junction generate a measurable voltage used to determine temperature.
Operating on the Seebeck Effect principle, thermocouples generate voltage proportional to temperature changes and the properties of the metals used.
Composed of two insulated wires from different metals connected to a measuring device, thermocouples serve as safety and monitoring tools for various processes and equipment.
Thermocouple assemblies are engineered for harsh, severe, and demanding environments, with selection based on temperature range, ambient atmosphere, media type, required accuracy, and response speed.
