0.3mm/0.4mm/0.5mm R Type Platinum Rhodium Thermocouple Bare Wire

Introduction:

The composition materials of R-type thermocouple bare wire are usually platinum-rhodium alloy wire (87% platinum, 13% rhodium) and pure platinum wire. This combination has good high-temperature stability and high accuracy, making the R-type thermocouple bare wire suitable for high-temperature measurement environments.

R-type thermocouple bare wire is a common thermocouple temperature measurement device, which is widely used in industrial control and scientific research fields in high-temperature environments. It consists of two alloy wires of different metals and measures temperature changes through the thermoelectric effect.

The structure of the R-type thermocouple bare wire is relatively simple and consists of two alloy wires. One end of the two wires is connected together to form a measurement point, and the other end is connected to a temperature measurement device, such as a temperature transmitter or data acquisition system. The measuring point is exposed to the environment to be measured, and temperature changes will cause a slight potential difference between the alloy wires. By measuring this potential difference, the temperature of the environment can be accurately calculated.

Type R thermocouple bare wire has many advantages, such as a wide high temperature measurement range (usually from 0 degrees Celsius to 1768 degrees Celsius), higher accuracy and reliability, and faster response time. It also has good corrosion resistance and low thermocouple resistance drift, making it suitable for applications requiring high accuracy and long-term stability.
