K-type Armored Thermocouple WRNK-191 Probe Temperature Sensor PT100/E/J High-precision Thermal Resistance Probe

The WRNK-191 K type armored thermocouple operates based on the principle of the thermoelectric effect. Its interior is composed of two different conductors (nickel-chromium – nickel-silicon) forming a closed circuit. One end is the measuring end (directly in contact with the object being measured for temperature measurement), and the other end is the reference end (used for wiring).When there is a temperature difference between the measuring end and the reference end, a thermoelectric potential will be generated in the circuit. The magnitude of this thermoelectric potential corresponds to the temperature difference between the two ends. The thermoelectric potential is converted into an intuitive temperature value through the matching instrument.
