Working principle
The working principle of RTD thermocouple temperature sensor probe WZP2-231 is to weld two ends of conductors with different components into a loop. The direct temperature measuring end is called the measuring end, and the terminal is called the reference end. When there is a temperature difference between the measuring end and the reference end, thermal current will be generated in the circuit. When connecting the display instrument, the instrument will indicate the temperature value corresponding to the thermoelectric electromotive force generated by the thermocouple. The thermoelectric EMF of armored thermocouple will increase with the temperature of the measuring end. The size of thermoelectric electromotive force is only related to the conductor material and the temperature difference at both ends of the armored thermocouple, and has nothing to do with the length and diameter of the thermoelectric electrode.
Structure
The structure of RTD thermocouple temperature sensor probe WZP2-231 is composed of conductor, insulating magnesium oxide and repeatedly drawn stainless steel protective tube. Armored thermocouple products are mainly composed of junction box, terminal block and armored thermocouple, and are equipped with various installation and fixing devices.
