WRET-01 Compression Spring Fixed Thermocouple
WRET-01 compression spring fixed nickel-chromium-copper-nickel thermocouple closes the thermocouple end to the surface of the measured object through a compression spring to improve the reliability and accuracy of the measurement. It can be used with display instruments to directly measure the temperature in the range of 0～400℃. The thermocouple has a flexible extension wire, which can be bent freely, has the characteristics of short thermal response time, and convenient use. It is suitable for industries such as plastic machine, textile, food and so on.
The working principle, indexing characteristics and allowable deviation of WRET-01 type thermocouple, reference junction (cold junction) temperature compensation, and connection method with display measuring instrument are the same as general thermocouple.
The structure of WRET-01 type thermocouple is shown in the figure, which is composed of protective tube, mounting bolt, locking sleeve, spring and thermal resistance wire.
The installation method of WRET-01 type thermocouple is shown in the figure. Fix it on the object under test. First tighten the connecting bolt on the object under test, then close the thermocouple to the object under test, tighten the clamp screw, and finally tighten Lock the ferrule tightly.
