Product Description

Ceramic Tubes Insulators for Temperature Sensor

Product Description

Ceramic Tubes Insulators for Temperature Sensor are mainly used to protect the thermometric element, to isolate the thermometric element from the outside, and to reduce or prevent the element from being eroded, oxidized or damaged by external substances during use.
 

Materials:
Al2O3: 99.7% Al2O3, 99%Al2O3, 95%Al2O3, 85%AL2O3, the higher the alumina content, the higher the use temperature;

Regular dimension:
 

1. Outer diameter:3mm-25mm;
2. Maximum length 2500mm;
3. Thickness: by dimension scale of product 0.5mm to 4mm.

Our Advantages

Feature of Ceramic Tubes Insulators for Temperature Sensor

1. Thermal stability: Alumina can be used in oxidizing and reducing atmospheres up to 1600ºC and vacuum furnaces up to 1750ºC.
2. Fully dense: Alumina provides an impermeable tube that prevents contamination and can be used to form air-tight components.
3. High chemical resistance: Alumina is chemically inert and will not be corroded by water or steam. It resists corrosive substances, such as strong acids or bases, even at high temperatures.
4. Electrical insulation: Alumina is also widely used as an electrical insulation material. It can be used for insulators that operate at high temperatures.
