WR-NM series wear-resistant thermocouple

Product introduction

WR-NM series wear-resistant thermocouple is majored used in the case of temperature measurement of low temperature medium which will cause serious damage to protective tubes. It is widely used in power plant of circulating fluidized bed, cement plants and chemical plants. Our company have a number of high-tech products in a leading international level in wear-resistant thermal resistance industry. Under the premise of no affecting temperature lag, the wear resistant materials of special process have solved completely the service life of circulating fluidized bed boiler temperature measuring thermocouple. The protective casing is wear-resistant,  high temperature oxidization resistant, sulfied resistant, liquid iron powder resistant,  limestone cement material corrosion resistant, anti-scouring, vibration resistant an so on. It makes the service life of temperature measurement thermal resistance longer.
