Industry Information
Compression spring fixed thermocouple is a temperature measuring element suitable for textile, plastic, petrochemical industry and other industries
2012-2-27 10:34:13

通过压簧将热电偶端部与被测物的表面紧贴, 以提高测量的可靠性和准确性。 The wr □ t-01 compression spring fixed thermocouple uses the compression spring to closely attach the end of the thermocouple to the surface of the measured object to improve the reliability and accuracy of the measurement. Compression spring-type fixed thermocouples are used together with display instruments to directly measure temperatures in the range of 0 ~ 400 ℃. Compressed spring-type fixed thermocouples have flexible extension wires, which can be bent freely, have short thermal response time, and are easy to use. They are suitable for plastic extruder, light textile, food and other industries.

● Structural principle
的作用原理,分度特性及允许偏差,参比端(冷接点)温度补偿, 以及与显示测量仪表的联接方法均与一般热电偶相同。 The working principle, indexing characteristics and allowable deviation, reference junction (cold junction) temperature compensation of wret-01 type compression spring fixed thermocouple , and the connection method with the display measuring instrument are the same as the general thermocouple.

The structure of the compression spring type thermocouple is composed of a protection tube, a mounting bolt, a locking ferrule, a spring and a thermocouple wire.

● Installation method
The installation method of the compression spring type thermocouple is fixedly installed on the measured object, and then the connection bolt is tightened on the measured object.
On the object, place the thermocouple firmly on the object to be measured, tighten the ferrule screw, and finally tighten the locking ferrule.


是适用于纺织、塑料、石化工业等行业的测温元件,它带有软性金属屏蔽延长线,可以自由弯曲,热响应时间小,结构简单,接触可靠,使用方便,与显示仪表配套使用,可直接测量0~400℃范围内温度。 WRET compression spring fixed thermocouple is a temperature measuring element suitable for textile, plastic, petrochemical industry and other industries. It has a flexible metal shield extension cord, which can be bent freely, has a short thermal response time, simple structure, reliable contact, and is used. Convenient, it can be used with display instrument to directly measure the temperature in the range of 0 ~ 400 ℃. The working principle, uniqueness, allowable deviation, and connection method of the WRET type compression spring fixed thermocouple are the same as those of ordinary thermocouples.

Compression spring-fixed nickel-chromium-copper-nickel thermocouple uses the compression spring to closely attach the end of the thermocouple to the surface of the measured object to improve the reliability and accuracy of the measurement. It is used in conjunction with display instruments, etc., and can directly measure the temperature in the range of 0 ~ 400 ℃. Thermocouples have flexible extension wires, which can be bent freely, have a short thermal response time, and are easy to use. They are suitable for industries such as plastic dispensing, light textile, and food. Structural principle The working principle, indexing characteristics and allowable deviation, reference junction (cold junction) temperature compensation of the WRET-01 type thermocouple, and the connection method with the display measuring instrument are the same as the general thermocouple. The structure of WRET-01 type thermocouple is shown in the figure, which consists of protection tube, mounting bolts, locking sleeves, springs and thermal resistance wires.
