Industry Information
Platinum and rhodium thermocouples are used in high temperature applications during production
2012-4-9 10:57:09


是由两种不同成分的导体两端接合成回路时,当两接合点温度不同时,就会在回路内产生热电流。 When a platinum-rhodium thermocouple is a circuit composed of two conductors with different components connected to each other, a thermal current will be generated in the circuit when the two junctions have different temperatures. If there is a temperature difference between the working end and the reference end of the thermocouple, the display meter will indicate the temperature value corresponding to the thermoelectric potential generated by the thermocouple. The thermoelectric heat of a platinum rhodium thermocouple will increase as the temperature of the measuring end rises. Its size is only related to the thermocouple material and the temperature at both ends, and has nothing to do with the length or diameter of the thermal electrode. The shapes of various platinum-rhodium thermocouples are often very different due to their needs, but their basic structure is roughly the same. They are usually composed of main components such as thermal electrodes, insulation protection tubes and junction boxes. WR series industrial platinum-rhodium thermocouple is also called precious metal thermocouple. As a temperature measurement sensor, it is usually used with temperature transmitters, regulators and display instruments to form a process control system to directly measure or control various production The temperature of fluid, steam and gas medium and solid surface in the range of 0-1800 ℃ during the process.

适用于各种生产过程中高温场合,广泛应用于粉未冶金,烧结光亮炉,真空炉,冶炼炉,玻璃,炼钢炉及陶瓷及工业盐浴炉等测温。 Platinum and rhodium thermocouples are suitable for high temperature applications in various production processes, and are widely used for temperature measurement in powder metallurgy, sintering bright furnaces, vacuum furnaces, smelting furnaces, glass, steelmaking furnaces and ceramic and industrial salt bath furnaces. Platinum and rhodium thermocouples are also called high-temperature-resistant noble metal thermocouples, which are divided into three types: S-type thermocouples (platinum-rhodium 10-platinum thermocouples), R-type thermocouples (platinum-rhodium 13-platinum thermocouples), and B-type thermocouples ( Platinum rhodium 30-platinum rhodium 6 thermocouple), mainly divided into single platinum rhodium and double platinum rhodium, are suitable for various high temperature occasions, and are widely used in the temperature measurement field in the production process of glass, ceramics and industrial salt bath furnaces. Among them, S-type thermocouple is the most commonly used in domestic industry. Due to the high measurement temperature, the general stainless steel protection tube can only withstand high temperature of 1000 degrees, and the stainless steel protection tube with a resistance of more than 1000 degrees is expensive. Therefore, corundum ceramic protection tubes are commonly used. High-purity corundum tubes can withstand high temperatures up to 1600 degrees. The disadvantage is that fragile.
