Abstract

The invention provides a length-adjustable thermocouple, which comprises a junction box, a protection assembly, a first conductor and a second conductor. The inner circumference of one end, far away from the junction box, of a first protection pipe is provided with a first annular groove; the groove wall of the first annular groove is provided with a first internal screw thread; one end of a second protection pipe is provided with a first annular ring; the periphery of the first annular ring is provided with a first external thread; the inner circumference of one end, away from the first annular ring, of the second protection pipe is provided with a second annular groove; the groove wall of the second annular groove is provided with a second internal screw thread; one end of a third protection pipe is provided with a second annular ring; the periphery of the second annular ring is provided with a second external thread; the inner circumference of one end, far away from the second annular ring, of the third protection pipe is provided with a third annular groove; the groove wall of the third annular groove is provided with a third internal screw thread; one end of a fourth protection pipe is provided with a third annular ring; the periphery of the third annular ring is provided with a third external thread; and the first conductor and the second conductor are connected to form a loop. The length-adjustable thermocouple realizes temperature measurement of temperature measurement regions in different heights.

Description

technical field [0001] The invention relates to the technical field of thermocouples, in particular to a thermocouple with adjustable length. Background technique [0002] In important industrial production processes such as petroleum, chemical industry, metallurgy, and electric power, measuring temperature with thermocouples is the most widely used method. Its main features are wide measurement range, relatively stable performance, simple structure, good dynamic response, and long-distance Transmission of electrical signals facilitates the realization of automatic control and centralized control. Thermocouples have the advantages of bending, high pressure resistance, fast thermal response time and fastening and durability. They can be used to directly measure the temperature of liquid, steam and gas media and solid surfaces in the range of 0-1000 °C in various production processes. temperature. In the prior art, a thermocouple with an appropriate length is usually selecte...
