Pressure spring fixed thermocouple

1Pressure spring fixed thermocouplestructural principle

Pressure spring fixed thermocoupleThe working principle, division characteristics and allowable deviation, temperature compensation of the reference end (cold junction), and connection method with the display measuring instrument are all the same as those of general thermocouples. The structure consists of protective tubes and installation bolts Composed of locking sleeve, spring, and thermocouple wire.

2Main technical parameters

Accuracy level: Level I or Level II

Thermal response time: ≤ 5 seconds

3Model

The WRET-01 pressure spring fixed nickel chromium copper nickel thermocouple uses a pressure 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. It is used in conjunction with display instruments and can directly measure temperatures within the range of 0-400 ℃. Thermocouples come with flexible extension wires that can be bent freely, have a small thermal response time, and are easy to use. They are suitable for industries such as plastic extrusion, textile, and food.

structural principle

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

The structure of WRET-01 thermocouple is shown in the figure, consisting of protective tube, mounting bolt, locking sleeve, spring, and thermal resistance wire.

Installation method

The installation method of WRET-01 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.
