Platinum rhodium thermocouple

1, Product Overview
The WR series industrial platinum rhodium thermocouples, also known as precious metal thermocouples, are temperature measurement sensors that are usually used in conjunction with temperature transmitters, regulators, and display instruments to form a process control system. They are used to directly measure or control the temperature of fluids, steam, gas media, and solid surfaces within the range of 0-1800 ℃ in various production processes.
Platinum rhodium thermocouples are composed of two conductors with different compositions connected at both ends to form a circuit. When the temperature of the two junction points is different, thermal current will be generated in the circuit. If there is a temperature difference between the working end and the reference end of the thermocouple, the display instrument will indicate the temperature value corresponding to the thermoelectric potential generated by the thermocouple.
The thermoelectric heating of platinum rhodium thermocouples will increase with the temperature of the measuring end, and its size is only related to the thermocouple material and the temperature at both ends, and is independent of the length and diameter of the thermoelectric electrode. The appearance of various platinum rhodium thermocouples is often very different due to needs, but their basic structure is generally the same, usually composed of main components such as thermal electrodes, insulation sleeve protective tubes, and junction boxes.
2, Product application
Platinum rhodium thermocouples are suitable for high-temperature situations in various production processes, and are used for temperature measurement in powder metallurgy, sintering bright furnaces, vacuum furnaces, smelting furnaces, glass, steelmaking furnaces, ceramic and industrial salt bath furnaces, etc.
