Thermocouple WRN2-630 WRN2-631 WRN2-632 WRN2-633
A thermocouple is a commonly used temperature sensing element in temperature measurement instruments. It directly measures temperature and converts the temperature signal into a thermoelectric potential signal, which is then converted into the temperature of the measured medium by electrical instruments (secondary instruments).
The shapes of various thermocouples can vary greatly depending on the application, but their basic structure is generally similar. They typically consist of a thermoelectric element, insulating sheath, protective tube, and connection box, and are usually used in conjunction with display instruments, recording instruments, and electronic regulators.
