WRNK-321 WRNK-331 WRNK-391 WRNK2-391 Armored thermocouple

Overview

As a temperature measurement sensor, WRNK-321 WRNK-331 WRNK-391 WRNK2-391 Armored thermocouple are usually used in conjunction with temperature transmitters, regulators and display instruments to form a process control system to directly measure or control fluids, Temperatures such as steam and gaseous media and solid surfaces. Armored thermocouples have many advantages such as flexibility, high pressure resistance, fast thermal response time and durability. They are the same as industrial assembled thermocouples. They are used as temperature sensors and are usually matched with display instruments, recording instruments and electronic regulators use.

Working principle of WRNK-321 WRNK-331 WRNK-391 WRNK2-391 Armored thermocouple

The working principle of the armored thermocouple is that the two ends of the conductor of different components are welded to form a loop. The direct temperature measurement terminal is called the measurement terminal, and the terminal is called the reference terminal. When there is a temperature difference between the measuring terminal and the reference terminal, a thermal current will be generated in the loop. When the display instrument is connected, the corresponding temperature value of the thermoelectromotive force generated by the thermocouple will be indicated on the instrument.The thermoelectromotive force of the sheathed thermocouple will increase with the increase of the temperature of the measuring end. The size of the thermoelectromotive force is only related to the conductor material of the sheathed thermocouple and the temperature difference between the two ends, and has nothing to do with the length and diameter of the thermoelectrode.
