W-Re thermocouple is one kind of tungsten products. Thermo-emf output conforms to the ASTM standard.
Chemical composition of W-Re thermocouple:
Characteristics and applications of W-Re thermocouple:
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.
