What waste electrical appliances have platinum rhodium wire

As long as it is a waste home appliance that can measure temperature, it has platinum rhodium wire, such as refrigerators, microwave ovens, ovens, gas water heaters, range hoods, air conditioners, electric heaters, electric pressure cookers and so on. Platinum-rhodium wire is a platinum-based rhodium-containing binary alloy, which is a continuous solid solution at high temperature and is used in almost all industrial fields.

Platinum-rhodium wire has the advantages of the highest accuracy, the best stability, wide temperature measurement area, long service life and high temperature measurement upper limit among the thermocouple series. It is suitable for oxidizing and inert atmospheres, and can also be used in vacuum for a short time. .

Platinum-rhodium thermocouple is also known as high-temperature precious metal thermocouple. Platinum-rhodium is divided into single platinum-rhodium and double platinum-rhodium. As a temperature measurement sensor, it is usually used in conjunction with temperature transmitters, regulators and display instruments to form a process control system. It can improve the thermoelectric potential, oxidation resistance and acid corrosion resistance of the alloy to platinum. It can be used as the thermocouple wire in the thermocouple to directly measure or control the temperature of fluid, steam and gas medium in the range of 0-1800℃ in various production processes.
