Industrial 4 Small Holes Ceramic Insulator Alumina Ceramic Tube Thermocouple Tube

Product name: 4 Holes Alumina Ceramic Insulating Core Thermocouple Ceramic Tube
Color: white/Ivory

Size: Various/ customized

Ceramic alumina tube and insulator are used in thermocouple assembly which applied for high temperature messuring.
Al2O3 content determines the measuring temperature level, Al2O3 content higher, the temperature is higher.
Alumina Tubes is the the workhorse of the advanced technical ceramic tubes. It has good mechanical and electrical properties, wear resistance and corrosion resistance. It has relatively poor thermal shock resistance.

Features:

-Hard, wear-resistant

-Excellent dielectric properties from DC to GHz frequencies
-Resists strong acid and alkali attack at elevated temperatures
-Excellent size and shape capability
-High strength and stiffness
-High thermal shock resistance

Application:
Mainly used in thermocouple temperature sensor, continuous temperature sensor of molten steel, various industrial furnaces (including vacuum furnace, carburizing furnace, wire winding furnace, atmosphere furnace, etc.). It is widely used in petrochemical, textile, electronics, instrumentation, machining, military and other industries. Among them, the protection tube for thermocouple temperature sensor is mainly used to protect the temperature sensor element, isolate the temperature sensor element from the outside, and reduce or prevent the element from being corroded, oxidized or damaged by external substances during use. In use, the temperature sensor element with good insulation protection is set in the protective tube, and then the open end and the coupling head are glued and sealed together with high temperature cement. When measuring temperature, insert the sealed end into the temperature sensor area, and avoid rapid cold and rapid heat when using, so as to avoid excessive damage to the protection tube.
