Description

Technical Field

[0001] The invention relates to the technical field of thermocouple temperature sensors, and in particular to a reforming method for reusing a K-type thermocouple temperature sensor. Background Art

[0002] The armored probe thermocouple temperature sensor is a temperature measurement device that integrates a thermocouple element with a metal protective sheath and insulating material. It features high-temperature resistance, vibration resistance, and fast response. When selecting a thermocouple, the type and sheath material must be matched based on the temperature range, environmental corrosiveness, and installation requirements. During installation, attention should be paid to insertion depth and grounding. It is widely used in industrial high-temperature scenarios.

[0003] For thermocouple temperature sensors with armored probes purchased on the market, they will be disassembled and assembled many times for temperature testing throughout their actual service life, and they will be damaged. It is a waste to directly eliminate them. Therefore, we provide a reusable modification method to solve this problem. Summary of the Invention

[0006] Damaged thermocouple temperature sensor treatment: Use pliers to cut open the bulkhead metal tube and remove the insulating sheath, cut off the burnt section of the connection between the first and second metal wires and separate them.

[0007] Assembly process: strip off 1~2cm of the insulation outside the first metal wire and the second metal wire, and make the exposed parts of the first metal wire and the second metal wire fixedly connected.

[0008] Installation process: using sealant to stick the connection portion between the first metal wire and the second metal wire to the housing of the sealing device that needs to be sealed during use.

[0009] Furthermore, the exposed parts of the first metal wire and the second metal wire are connected by twisting.

[0010] Furthermore, the exposed parts of the first metal wire and the second metal wire are connected by welding.

[0011] Furthermore, the twisted connection of the first metal wire and the second metal wire is flattened.

[0012] Furthermore, the sealing device is an engine water tank.

[0013] Furthermore, the sealing device is an engine intake pipe.

[0014] In the above technical solution, the method for reusing a K-type thermocouple temperature sensor provided by the present invention has the following beneficial effects:

[0015] The present invention remodels the damaged sensor probe so that the damaged sensor can be reused for testing some temperature test requirements that do not require special tooling. By using sealant and adding a temporary shield to the modified thermocouple probe, it is also possible to more conveniently test air temperature, water temperature and other temperatures that require sealing, eliminating tooling procedures and being more convenient and quick.
