| Abstract: | This paper discusses how to prolong the using life of W-Re thermocouple, the advantage and fault using variable methods are compared, the protected prototype made of quartz glass under the temperature less than 1700℃ is proposed. It can prolong the life of W-Re thermocouple above more than five times. The protecting technology is stated and studied. |
