Ceramic Protection Tubes are used in applications where contamination from hostile environments or the cutting action of concentrated and direct flame impingement are factors. Such conditions usually require a noble metal thermocouple such as platinum and platinum alloys.
When selecting assemblies using ceramic components, the expected maximum temperatures must be considered. At elevated temperatures, some ceramic materials go through a glass phase. As silica is a prime contaminant of platinum, alumina protecting tubes and insulators are recommended for temperatures exceeding 2000ºF (1093ºC).

al2o3 ceramic tube for thermocouple protection

Thermocouple Protection Tube material:

Alumina 99.8% It has the most superior gas and vacuum tightness

and electrical insulating properties at elevated temperatures. It is non-reactive

and recommended for use with platinum, as well as tungsten

and molybdenum thermocouple alloys. The maximum service temperature is 1850°C.

Mulliteis recommended for most thermocouple applications.

It consists of a mullite type ceramic capable of withstanding temperatures up to 1650°C.

We can supply the products according to customer's drawings, samples and performance requirement.

Our industrial ceramic parts include, tube, rod, plate, disc, wafer, ring, seal, bearing, valves, pump plunger, beam, roller, shaft, screw, washer, sleeve, hunger, spacer, holder, carrier, insulator, scissors, knife, slitter, tweezers, tools, fixture, clamp, chuck, nozzle, guide, frame, lining, and grinding media, milling ball or beads. These precision toleranced ceramic components or assemblies are used in a wide range of semiconductor, electronic, electrical, mechanical, chemical, automotive, textile and the other industrial engineering applications, due to their extreme hardness, more resistances to wear, heat, corrosion, high electric insulation, and low thermal expansion.
