Recently, the demand for measuring temperature using a glass-sealed thermistor has become increasingly widespread, and the objects to be measured have become diverse, including fixed objects, liquids, fluids, and gases. Also, the atmosphere in which the temperature sensor is used is
They are often used under poor conditions such as high temperature, high humidity, and the generation of harmful gases, which can cause temperature sensors to malfunction. Therefore, when using a glass-sealed thermistor as a temperature sensor, it is necessary to encase the thermistor in a metal or ceramic protective tube to create an airtight structure, or to apply thermally conductive paint to the exposed parts of the thermistor and lead wires. , and many other types have been devised.
以上のような現状から、本考案では、信頼度を

周にシリコンワニス等を含浸させて使用する。 Conventional glass-sealed thermistors include, for example, (Japanese Patent Publication No. 52-7535), which are inserted into a mold as shown in Figure 2 with the lead wire facing upward, and then After injecting glass powder into the empty space, the mold is passed through a furnace at a temperature near the softening point of the glass powder to seal the glass powder around the outer periphery of the glass-sealed thermistor. After cooling, the work is complete when the product is taken out. If it is desired to further improve reliability, the outer periphery of the glass-sealed thermistor is impregnated with silicone varnish or the like after the above-mentioned operation.
