Abrasion Resistant Thermocouples

The use of armored or high-temperature armored core, with different materials and specifications of wear-resistant casing, wear resistance, vibration resistance, thermal shock resistance performance，Widely used in core areas such as power plants, cement plants, metallurgy, and chemical industry.

Products Description

The use of armored or high-temperature armored core, with different materials and specifications of wear-resistant casing, wear resistance, vibration resistance, thermal shock resistance performance, in a variety of high degree of wear in the harsh occasions of the product service life can be several times higher than ordinary products.

According to the different temperature to be measured, the selected wear-resistant protective tube material is also different, using flange connection or threaded connection, can be used for long-term temperature measurement in the range of 0-1400 degrees, is the metallurgy, chemical industry, cement plant, power plant, fluidized bed boiler industry used in the most ideal measurement temperature sensor in high temperature and wear-resistant environment.

There are two selections

1. Wear-resistant superalloy: According to the characteristics of high-temperature wear environment, the explosion-proof thermocouple is specially designed to be pure alloyed by vacuum smelting, which has high temperature oxidation resistance and special wear-resistant superalloys with extremely high high temperature strength, which are forged and drilled as a whole. Less processing defects, high reliability, good comprehensive performance of high temperature strength and wear resistance, high price, and the use temperature is 800~1200 °C.

2.Lon-injected tungsten carbide: Tungsten carbide particles are injected on the surface of the casing using ion-injection technology with stainless steel as the matrix. It has high hardness, high strength, high toughness, especially wear-resistant, wear-resistant layer thickness of 0.2mm, external hardness and internal toughness.
