Description

Technical Field

[0001] The utility model belongs to the technical field of thermocouples, and particularly relates to a novel anti-corrosion thermocouple. Background Art

[0002] Thermocouples have the advantages of fast response, wide measurement range, good linearity and stability, and are widely used in temperature measurement in industry, laboratories and other fields. In order to improve the corrosion resistance of thermocouple sleeves, anti-corrosion coatings are usually applied in the prior art to effectively protect the thermocouple sleeves from chemical erosion, oxidation, corrosion, etc., and extend their service life.

[0003] For example, a Chinese patent with publication number CN217953713U discloses an anti-corrosion thermocouple, including a wiring control box, a thermocouple core assembly is arranged at the bottom end of the wiring control box, an anti-corrosion sleeve is arranged on the outside of the thermocouple core assembly, an anti-corrosion protective shell is arranged on the top end of the anti-corrosion sleeve, a rotation adjustment assembly is arranged inside the anti-corrosion protective shell, a manual adjustment limit assembly is arranged on the top end of the wiring control box, a wiring cable is arranged on one side of the wiring control box, and the rotation adjustment assembly is composed of an adjustment rod, a driving bevel gear and a driven bevel gear.

[0004] Although the above can avoid the problem of bending or single-sided perforation of the anti-corrosion sleeve due to fluid impact on one side, there are still shortcomings that need to be improved. When the anti-corrosion sleeve is frequently subjected to large impact force on one side, it is easy to deform, and the number of impact resistance is small, thereby reducing the service life of the anti-corrosion sleeve. In addition, the anti-corrosion sleeve is integrally connected under the junction box. When each contact surface of the anti-corrosion sleeve is greatly deformed, it is inconvenient to replace the anti-corrosion sleeve, which is not conducive to the use of thermocouples.
