Platinum rhodium wire is platinum based binary alloy containing rhodium, for continuous solid solution at high temperature. Rhodium alloy can be improved for platinum thermoelectric potential and ability to resist oxidation and acid corrosion. PtRh5, PtRhl0, PtRhl3, PtRh30 and PtRh40 alloy. More than 20% Rh alloy does not dissolve in water. Mainly used for thermocouple materials, PtRhl0 / Pt, PtRh13 / Pt, etc, used for the thermocouple wire in the thermocouple, to directly measure or control in the production of a variety of 0 Fluid over a range of 1800 ℃, steam and gas medium and solid surface temperature advantages: platinum rhodium wire in the thermocouple series has high accuracy, good stability, test your area wide, long service life, high temperature limit, etc. Suitable for oxidation and inert atmosphere, can also be short term used in vacuum, but does not apply to reducing atmosphere or containing metal or nonmetal steam atmosphere. Industrial thermocouple of platinum rhodium wire type B, S type, R type, platinum rhodium thermocouple is also called high temperature thermocouple, precious metals platinum rhodium have single platinum rhodium ( Platinum rhodium - 10 Platinum rhodium) And double platinum rhodium ( Platinum rhodium - 30 Platinum rhodium (6) , them as temperature measurement sensor, usually with temperature transmitter, controller and display instrument, such as process control system, to directly measure or control in the production of a variety of 0 Fluid over a range of 1800 ℃, steam and gas medium and solid surface temperature. Used in industry are: steel, electricity, petroleum, chemical industry, glass fiber, food, pharmaceutical, ceramics, glass, nonferrous metals, heat treatment, aerospace, metallurgy, carbon powder, coking, printing and dyeing, etc. Almost all industrial fields.
