NiCr/Ni thermocouples, also referred as K-type thermocouples, consist of two wires. One wire is of pure nickel, the other is made of a nickel-chrome alloy. Through the Seebeck-effect, a thermoelectric voltage is generated at the location where the two wires contact each other. The contact point is the measuring point. The voltage generated at the contact point is temperature dependent. The value of the voltage present can be converted to be available in degree temperature. The range of application for these thermocouples lies between 0°C and 1100°C, with an accuracy of (+ -) 1,5°C.
