Thermocouple Sensor K Type
Thermocouple Sensor K Type is the most widely used thermocouple at present, and its usage is the sum of other thermocouples. Thermocouple sensor K type has the advantages of good linearity, large thermoelectric potential, high sensitivity, good stability and uniformity, strong anti-oxidation performance, and low price. It can be used in an oxidizing inert atmosphere.
What’s The Working Principle Of Thermocouple Sensor K Type?
The Thermocouple Sensor K Type is a thermometal thermocouple that combines two distinct metals to produce an induced voltage that varies with temperature. Electric potential variations are created on both ends of two distinct metal wires as a result of temperature changes. Both the extension wire and the thermocouple have positive and negative poles. In a variety of production processes, thermocouple sensor K type directly monitors the temperature of liquids, steams, gases, and other fluids as well as solid surfaces between 0 and 1100°C.
