Tungsten Rhenium Alloy Thermocouple Wire

Tungsten Rhenium Alloy Thermocouple Wire Description

Thermocouple wire is used to manufacture thermocouple probes in order to sense temperature using the point of cold junction compensation (cjc end). A thermocouple is a sensor for measuring temperature, that consists of two dissimilar metals that are joined together at the sensing end. At the cjc end, the millivolt value provided by the thermocouple represents the difference in temperature of the sensing end as compared to the cjc end (also called the reference end).

The use of pure tungsten in thermocouple applications, as the positive element, posed a problem when heating tungsten above its recrystallization temperature (1200℃). This causes the wire to become brittle when reintroduced to room temperature. The addition of rhenium significantly reduces the brittle characteristics of Tungsten at room temperature.

We also produce armoured W-Re thermocouple wire per request.
