WRET-01 and WRNT-01 spring-loaded thermistors use a compression spring to tightly adhere the end of the thermistor to the surface of the object being measured, in order to improve the reliability and accuracy of the measurement. The spring type thermistor is used in conjunction with display instruments and can directly measure temperatures within the range of 0-400 ℃. The compression spring type thermistor has flexible extension wires that can be bent freely, with characteristics such as small thermal response time and easy use. It is suitable for industries such as plastic extruders, textiles, and food.

●structural principle

The working principle, division characteristics, and allowable deviation of WRET-01 compression spring thermistor, temperature compensation at the reference end (cold junction), and its relationship with
The connection method of the display measuring instrument is the same as that of a general thermocouple.
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 method

The installation method of WRET-01 type compression spring thermistor is shown in the figure. It is fixedly installed on the tested object, and the connecting bolts are first tightened on the tested object
On the object, press the thermocouple tightly against the object being measured, tighten the sleeve screw, and finally tighten the locking sleeve.
