Alumina ceramic probe support sleeve

Aluminum oxide ceramic probe support sleeve is a high-performance precision component designed specifically for harsh industrial environments such as high temperature, corrosion, and wear. Made by precision sintering high-purity alumina ceramic material (Al ₂ O3 content ≥ 95%), it has excellent mechanical strength, high temperature resistance, corrosion resistance, and insulation performance, and is widely used in the positioning, support, and protection of various sensors, probes, and measuring instruments.

Core advantages of the product

1. Excellent high temperature resistance performance
   Long term use temperature can reach 1600 ℃, with higher short-term temperature tolerance, suitable for extreme environments such as high-temperature kilns and molten metal measurement.
2. Excellent corrosion resistance and wear resistance
   It has strong resistance to most acids, bases, and chemical media, with high hardness (HV ≥ 1500), significantly extending the service life of the probe.
3. High insulation and stability
   High volume resistivity, excellent dielectric strength, and stable electrical insulation performance even at high temperatures, ensuring accurate and reliable measurement signals.
4. Precision structure and dimensional stability
   Adopting precision molding and processing technology, the dimensional tolerance can be controlled within ± 0.1mm, the coefficient of thermal expansion is low, and it will not deform after long-term use.
5. Customized adaptation capability
   Support comprehensive customization of structure, aperture, threads, etc. based on probe size, installation method, and environmental requirements.

Main application areas
-High temperature industrial measurement: support and protection of thermocouples, thermistors, and oxygen content probes
-Metallurgy and Casting: Temperature and Composition Detection of Molten Metals such as Molten Steel and Aluminum Liquid
-Chemical and Energy: Sensor Installation in High Temperature and High Pressure Corrosive Environments in Reactors and Pipelines
-Research and Laboratory: Supporting Components for Experimental Instruments in High Temperature Furnaces and Vacuum Environments
-Semiconductor manufacturing: insulation positioning components in wafer processing and CVD equipment

What problems can we solve?

1. Short lifespan of the probe: Traditional metal support sleeves are prone to wear and tear in high-temperature corrosive environments, while ceramic sleeves can extend the lifespan of the probe by 3-5 times
2. Measurement signal interference: Metal sleeves may cause electromagnetic interference, while the high insulation of ceramics ensures signal purity
3. Insufficient installation accuracy: Customized design ensures perfect matching with probes and equipment, reducing installation errors
4. Poor adaptability to multiple environments: A complete set can simultaneously meet multiple harsh conditions such as high temperature, corrosion, and wear

Customer Application Case (Anonymous)

1. A large steel group
   In the measurement of molten steel temperature in continuous casting process, the average service life of the original stainless steel support sleeve is only 2 weeks. After replacing our customized alumina ceramic sleeve, the service life has been extended to 8 weeks, saving maintenance costs of about 400000 yuan per year and improving measurement data stability by 25%.
2. A chemical equipment manufacturer
   Used for pH probe protection in high-temperature corrosive environments of chlor alkali reaction vessels. We have designed a ceramic support sleeve with a flange connection structure, which perfectly matches the existing interface and greatly improves corrosion resistance. The customer has reported that the product has been continuously used for 18 months without any failure records.
3. Materials Laboratory
   In a 1600 ℃ vacuum sintering furnace, it is necessary to support thermocouples for precise temperature field measurement. We provide high-purity (99.5% Al ₂ O ∝) thin-walled ceramic sleeves, which not only ensure insulation strength but also minimize interference with the thermal field, significantly improving the repeatability of experimental data.

Although the alumina ceramic probe support sleeve is a small component, it directly affects the reliability, accuracy, and lifespan of the entire measurement system. Choosing a professional and reliable supplier is to provide a long-term guarantee for your core equipment.
