Description
The function of the compensation wire of the tungsten rhenium thermocouple is to extend the temperature measurement system composed of the cold end of the mobile thermocouple and the display instrument. Compensation wires are generally used in thermocouples, and the insulation and sheath of thermocouple compensation wires are made of different materials according to the requirements of the environment. The sheath materials include polyvinyl chloride, fluoroplastics, and low-smoke and low-halogen polyvinyl chloride. And several kinds of alkali-free glass filaments, imported high-quality fluoroplastics can withstand temperature of 260℃, and adopt a new continuous extrusion process, so that the product has excellent acid resistance, alkali resistance, abrasion resistance and non-flammability. It can be immersed in oil and water for long-term use .
The temperature of thermocouple compensation wire can be -60-260℃, which belongs to the contemporary domestic advanced level. The series of products are mainly used in various temperature measuring devices. The compensation wire models are divided into WC3/25, WRe3-WRe25, WC5/26 according to the product variety.
WRe5-WRe26. Product characteristics of thermocouple compensation wire: The compensation wire can work in the environment of -60～260℃, which is a very ideal automation unit. It has been widely used in the single-point or multi-point connection of automatic temperature measuring instruments in the petroleum, chemical, metallurgical, electric power and other sectors.
