WRR-131 R-type Platinum Rhodium Thermocouple

Platinum rhodium thermocouple, also known as precious metal thermocouple, is commonly used as a temperature measurement sensor in conjunction with temperature transmitters, regulators, and display instruments to form a process control system for direct measurement or control

The temperature range of fluids, vapors, gases, and solid surfaces in various production processes is 0-1800 ℃.

Platinum rhodium thermocouple is 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, a 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

When there is a difference, the display instrument will indicate the temperature value corresponding to the thermoelectric potential generated by the thermocouple.
The thermoelectric heating of a platinum rhodium thermocouple will increase with the temperature at 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. Various platinum rhodium thermocouples

The appearance is often very different due to needs, but their basic structure is roughly the same, usually composed of main components such as hot electrodes, insulation sleeves, protective tubes, and junction boxes.
