| Abstract: | This paper was stressed to introduced the structures, properties and the present state of applications for the new type of the cheap metal thermocouples-Ni-Cr-Si/Ni-Si and W-Re thermocouples.Antioxidation technique, stability and working life of the W-Re thermocouple were studied. The results indicated that the solid antioxidation W-Re thermocouple replacing the Pt-Rh thermocouple applied in the industrial processes are not only stable in property, long in working life, but also cheap in price and convenient in maintenance. Application of the W-Re thermocouple will become an inevitable tendency in the future. |
