Piezoreed thermocouple by piezoreed the end of the thermocouple and the surface of the measured object close to improve the reliability and accuracy of measurement. Compressed-spring thermocouple is used with display instrument, which can directly measure the temperature in the range of 0~400℃. Spring thermocouple with soft extension wire, can be bent freely, with small thermal response time, easy to use and other characteristics, suitable for plastic extruder, textile, food and other industries.

Structural principle

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

The structure of the WRET-01 compression spring thermocouple is shown in the figure, consisting of protective tubes and mounting bolts. Locking sleeve, spring and thermocouple wire, etc.

Installation method

The installation method of WRET-01 type pressure-spring thermocouple is shown in the figure, fixed on the object under test, first tighten the connecting bolt on the object under test, and then the thermocouple close to the object under test, tighten the sleeve screw, and then screw the locking sleeve.
