Problems solved by technology

[0002] Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It directly measures temperature, and converts the temperature signal into thermal electromotive force signal, and converts it into the temperature of the measured medium through electrical instruments. The shape of various thermocouples is often very different due to needs. They are not the same, but their basic structures are roughly the same. They are usually composed of main parts such as galvanic wires and junction boxes. They are usually used in conjunction with display instruments, recording instruments, and electronic regulators. Thermocouples are mainly used for liquids, steam, and gases. The measurement of the temperature of the medium and the surface temperature of the solid. In the actual application of the thermocouple, because it is a precision measurement tool, it has high requirements for its accuracy. Due to the lack of technology of the traditional thermocouple, the relative diameter of the galvanic wire is relatively thick. Therefore, in the actual measurement, the detection response is slow, so there will be a certain delay while the data is displayed, and because the galvanic wire is thick, the measurement stability is relatively poor, so a thinner galvanic wire is used Processing ultra-fine thermocouples is a technical improvement that can be thought of in the current field, but there are certain technical gaps in the processing of ultra-fine thermocouples. In the existing technology, the thinnest thermocouple wire can only reach 0.5mm , cannot meet the actual application requirements
