Tungsten Rhenium Wire/Cable WRe3-WRe25/WRe5-WRe26 Thermocouple Wire Type C

Introduction:

Tungsten-rhenium alloy wire C-type thermocouple bare wire is a commonly used temperature measurement device, mainly used in the fields of industrial control and scientific research in high-temperature environments. It consists of two tungsten-rhenium alloy wires of different metals and measures temperature changes through the thermoelectric effect.

The structure of the C-type thermocouple bare wire is relatively simple. It consists of two tungsten-rhenium 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. Tungsten-rhenium alloy wire WRe5-26. Tungsten-rhenium alloy containing 5% rhenium and tungsten-rhenium alloy containing 26% rhenium. Maximum temperature range -0-2320 °C.
Tungsten-rhenium alloy wire has good high temperature resistance and mechanical strength, making the C-type thermocouple bare wire suitable for long-term use in high-temperature environments.

During the temperature measurement process, the measuring point of the C-type thermocouple bare wire is exposed to the environment to be measured, and temperature changes will cause a slight potential difference between the tungsten-rhenium alloy wires. There is a specific relationship between this potential difference and temperature, known as the thermoelectric effect. By measuring this potential difference, the temperature of the environment can be accurately calculated.

Tungsten-rhenium alloy wire C-type thermocouple bare wire has many advantages, such as a wide high temperature measurement range (usually from 0 degrees Celsius to 2300 degrees Celsius), higher accuracy and reliability, and faster response time. It also offers excellent corrosion resistance and low thermocouple resistance drift, making it suitable for applications requiring high accuracy and long-term stability.
