Like thermometers, ceramic temperature measuring rings can also output electrical signals or digital signals for data collection and processing. Therefore, it can be said that ceramic temperature measuring rings are similar to thermometers in industrial applications and are a common device for measuring temperature in high-temperature environments.
According to different manufacturing processes, ceramic temperature measuring rings can be divided into the following types:
Sintered ceramic temperature measuring rings: temperature measuring rings obtained by molding and heating ceramic powder. This manufacturing process can produce ceramic temperature measuring rings with high density and uniform structure, with advantages such as high-temperature stability and high mechanical strength. Sintered ceramic temperature measuring rings are usually made of ceramic materials such as alumina, silicon nitride, silicon carbide, and zirconium oxide.
Injection molded ceramic temperature measuring rings: temperature measuring rings are obtained by mixing the ceramic powder with an organic binder and then pressing and injection molding. This manufacturing process can produce ceramic temperature measuring rings with complex shapes and high precision, which are suitable for some special high-temperature measurement occasions.
Pressed ceramic temperature measuring rings: temperature measuring rings obtained by pressing ceramic powder in a mold. This manufacturing process can produce ceramic temperature measuring rings with certain shapes and sizes, which are suitable for some medium and low-temperature measurement fields.
According to different materials, ceramic temperature measuring rings generally include alumina, zirconium oxide, silicon nitride, and silicon carbide ceramic temperature measuring rings. According to market research, alumina ceramic temperature measuring rings account for the largest share of the market, because they have the advantages of relatively low price, good stability, and strong corrosion resistance, which are suitable for the measurement needs of most application scenarios. Silicon nitride, zirconium oxide, and silicon carbide ceramic temperature measuring rings have a relatively narrow application range and a small market share due to their high prices, but in some special high temperature, high pressure, corrosive gas, and other harsh environments, the application advantages of these materials are more obvious.
It should be noted that different manufacturing processes can produce different types of ceramic temperature measuring rings with different characteristics and scope of application. The selection of a suitable ceramic temperature measuring ring should be based on actual needs. At the same time, with the continuous development of ceramic materials and manufacturing processes, more new manufacturing processes for ceramic temperature measuring rings may also appear.
