がある。Conventional thermocouple wires are, for example, PR, OA, CR.
The temperature sensed at the connected part is measured by connecting the wires specified in J Engineering S standards such as Olxc, CC, etc., but for that reason, the wire insulation powder Measures are being taken such as burying the wires inside the wires or installing overhead wires on insulators to prevent the wires from becoming shallower. In addition, there are various problems such as the need to ensure that the area around the heat-sensing portion of the wire has good heat conductivity in order to ensure temperature measurement.

。That is, the present invention provides a thermocouple wire in which the surface of the thermocouple wire is coated with finely divided ceramic pieces, fine powder, or the like. Therefore, the surface of the thermocouple wire is not used as is in the past.
In particular, since the coating material is made of ceramic material, it has excellent corrosion resistance, acid resistance, heat resistance, and perfect insulation.Furthermore, the sensing part can be made into a sensitive structure by thinning the coating, so it can be easily used as a cotton thermocouple. It can also coat thermocouples with minute diameters, so it adds sufficient flexibility to thermocouples with a diameter of 0.2 mm or less.

FIG. 1 is a diagram showing the shape of a wire of a thermocouple, one surface of which is coated with fine pieces of ceramic according to the present invention. FIG. 2 is an enlarged view of the partial cross-sectional shape of FIG. 1. 1 is the thermocouple wire itself, and 2 is a ceramic fine piece. 3 is an adhesive that joins the ceramic minute pieces of 2 and the thermocouple wire of 1. The bonding agent in step 3 is applied by dipping the surface of the wire in step 1 into the bonding solution in step 3 (= soaking it or painting it on the surface, then spraying fine pieces of ceramic on it, or rubbing it with a roller, etc.) to bond the thermocouple element. The entire surface of the wire is coated.In this way, the surface of the thermocouple wire can be coated with ceramic, so it can be used as is as it has high corrosion resistance, acid resistance, heat resistance, and insulation properties. It can be provided to the market at a lower cost than conventional products.
