The materials of wear-resistant thermocouples are as follows

1Iron aluminum ceramic protective tubeMaterial:Iron based materials containing aluminum and cleverly adding A12O3 powder can produce iron aluminum ceramic (TLC) with special gold content. By making the iron aluminum ceramic alloy into a thermocouple (resistor) protective tube, it becomes the most critical component of the iron aluminum ceramic thermocouple (resistor) - the iron aluminum ceramic protective tube. According to the working temperature, wear condition, medium type, pressure equation, different series of iron aluminum ceramic protective tubes are made. There are currently six series: TLC, TLC1, TLC2, TLC3, TLC4, and TLC5.
2、 3YC52, GH303, and K13200 heat-resistant and wear-resistant alloys: Special heat-resistant and wear-resistant alloy materials are used as temperature measuring outer protective tubes, with armored cores inside. They not only have high corrosion resistance to particle erosion, but also provide good protection for the inner core under high temperature conditions. Adopting flange or threaded connection form, it can maintain 0 for a long time∽1200℃Temperature measurement between them is an ideal temperature sensor used in high-temperature and wear-resistant environments in the metallurgical industry

III SiC Wear resistant hot blast stove: It adopts a new type of silicon carbide metal ceramic protective tube, with a high temperature of up to 1300 ℃, and the inner core is an S-division or B-division high-temperature armored core, specially suitable for temperature measurement in hot blast stove occasions.

4、 Wear resistant SiC metal ceramic: Using a recrystallized silicon carbide metal ceramic protective tube, the high temperature can reach 1300 ℃, and the interior is equipped with K-index or S-index armored core, which is specifically suitable for temperature measurement in high-temperature and wear-resistant working conditions such as cement kiln tail and circulating vulcanization bed.
