Pressure spring thermocouple

The compression spring thermocouple uses a compression spring to tightly adhere the thermocouple end to the surface of the measured object, in order to improve the reliability and accuracy of the measurement. The compression spring thermocouple is used in conjunction with display instruments and can directly measure temperatures within the range of 0-400 ℃. Compression spring thermocouples are equipped with flexible extension wires that can be bent freely. They have the characteristics of small thermal response time and easy use, and are suitable for industries such as plastic extruders, textiles, and food.

Structural principle

The working principle, division characteristics, allowable deviation, reference end (cold junction) temperature compensation, and connection method with the display measuring instrument of WRET-01 compression spring thermocouple are the same as those of general thermocouples.

The structure of WRET-01 pressure spring thermocouple is shown in the figure, consisting of a protective tube and mounting bolts Composed of locking sleeve, spring, and thermocouple wire.

installation

The installation method of WRET-01 compression spring thermocouple is shown in the figure. It is fixedly installed on the measured object. First, tighten the connecting bolts on the measured object, then tightly attach the thermocouple to the measured object, tighten the sleeve screws, and finally tighten the locking sleeve.
