Power station thermocouple (resistance)

WR□T-01 type compression spring fixed nickel-chromium-copper-nickel thermocouple uses the compression spring to make the end of the thermocouple close to the surface of the measured object to improve the reliability and accuracy of the measurement. The compression spring type fixed thermocouple is used in conjunction with the display instrument, etc., and can directly measure the temperature in the range of 0~400 °C. The compression spring type fixed thermocouple has a flexible extension wire, which can be bent freely, has the characteristics of small thermal response time and convenient use, and is suitable for plastic extruder, light textile, food and other industries.

●Structure principle of compression spring fixed thermocouple

The working principle of the WRET-01 type compression spring fixed thermocouple, the indexing characteristics and allowable deviation, the temperature compensation of the reference junction (cold junction), and the

The connection method of the display measuring instrument is the same as that of the general thermocouple.

The structure of the WRET-01 compression spring fixed thermocouple is shown in the figure, which consists of a protection tube, mounting bolts, locking ferrules, springs and thermocouple wires.

●Pressure spring type fixed thermocouple installation method

The installation method of the WRET-01 compression spring type fixed thermocouple is shown in the figure. It is fixed on the object to be measured, and the connecting bolts are first tightened on the measured object.

On the object, then close the thermocouple to the object to be measured, tighten the ferrule screw, and finally screw on the locking ferrule.
