Brief introduction:
W-Re thermocouple
is one kind of tungsten products. Thermo-emf output conforms to the ASTM standard. W-Re thermocouple is one kind of thermocouple which can resist high temperature.Chemical composition of W-Re thermocouple:
| W Re, (Positive) | W Re, (negative) | |||
| Element | Re | W | Re | W |
| Content,wt% | 3.00 | balance | 25.00 | balance |
Characteristics and applications of W-Re thermocouple:
W-Re thermocouple is featured by good linear relationship between temperature and electric potential, reliable thermal stability and cheap price.
As a replacement of Pt/PtRh, the W-Re thermocouple can be used in the steel making furnace for temperature measurement. As expansible thermocouple, the W-Re thermocouple costs only as low as one tenth of the Pt/PtRh one. Also the upper limit of the measured temperature with W-Re couple is about 1000℃ which is higher than that of Pt/PtRh couple.
W-Re thermocouple is easily oxidized, so it is suitably used in inert or dry hydrogen.
