Working principle
Armored thermocouple WRNK2-291 is a temperature measuring element that can directly measure temperature, convert temperature signals into thermoelectric electromotive force signals, and then measure the temperature of the measured medium through electrical instruments. Its working principle is that the electrode is composed of two different conductor materials. When there is a temperature difference between the measurement end and the reference end, a thermoelectric potential is generated. The thermocouple WRNK2-291 uses this principle for temperature measurement. One end directly used for measuring the temperature of the medium is called the working end (also known as the measurement end), and the other end is called the cold end (also known as the compensation end). The cold end is connected to a display instrument or supporting instrument and the display instrument will indicate the thermoelectric potential generated by the armored thermocouple WRNK2-291.
Characteristic
