High-purity Alumina Al₂O₃ Ceramic T Type Thermocouple Socket

High-purity Alumina Al₂O₃ Ceramic T Type Thermocouple Socket

Product Description

Ceramic Thermocouple Socket, with their irreplaceable high-temperature resistance, high insulation, and corrosion resistance, have become an indispensable standard configuration in modern industrial high-temperature temperature measurement. Their precision-machined multi-pole hole structure is compatible with various thermocouple models. In harsh high-temperature conditions such as metallurgy, chemical engineering, and heat treatment, they provide stable electrical insulation and signal transmission for thermocouples, while also resisting the erosion of complex environments such as high temperatures, corrosion, and vibration. They are key ceramic components in industrial automated temperature measurement equipment, combining high reliability and long lifespan. Choosing high-quality alumina ceramic thermocouple sockets lays a solid foundation for precise control and stable operation in industrial production.

Core material properties

1.Alumina ceramics introduction

Alumina (Al₂O₃) is the most widely used oxide ceramic material in industrial ceramics. It is classified into several grades according to purity. Thermocouple sockets typically use 95%-99.7% high-purity alumina, which combines excellent electrical insulation, high-temperature resistance, and mechanical strength.

Product Core Advantages

1.Exceptional high-temperature resistance

   Long-term operating temperature can reach 1600-1750℃, far exceeding that of plastic (<200℃) and ordinary metal sockets.

   It does not soften, melt, or decompose at high temperatures, maintaining structural integrity.

   Excellent thermal shock resistance, capable of withstanding rapid heating and cooling cycles.

2.Excellent electrical insulation

   Even in high-temperature environments above 1000℃, it maintains extremely high volume resistivity,effectively eliminating crosstalk and leakage between thermocouple signals, and ensuring accurate transmission of weak thermoelectric potential signals (in the microvolt range).

3.Excellent chemical stability

   Resistant to acid and alkali corrosion, and resistant to molten metal vapor and furnace gas erosion.

   Does not react with thermocouple electrode materials, avoiding contamination and signal drift.

   Excellent oxidation resistance, extending service life.

4.Reliable mechanical properties

   High hardness, wear resistance, and long insertion/removal life.

   Precision-machined sockets ensure a tight fit with the thermocouple plug.

   Vibration and shock resistant, adaptable to harsh industrial conditions.

5.Precise temperature measurement ensures

   Low thermal conductivity reduces heat loss along the socket, lowering measurement errors.

   Controllable material purity avoids interference introduced by impurity heat dissipation potential.

   Good dimensional stability prevents deformation at high temperatures, ensuring reliable contact.

Installation and Usage Specifications

1.Installation Points

    Alignment of Polarity: strictly connect according to the positive and negative markings to avoid measurement errors caused by reverse connection.

   Moderate Tightening: use moderate torque when tightening screws to prevent ceramic cracking.

   Stress Avoidance: leave sufficient bending allowance for the wires to prevent mechanical stress from being transmitted to the ceramic body.

   Sealing Protection: in high-temperature and dusty environments, it is recommended to use with a sealing gasket.
