Temperature measuring apparatus of high melting point metal carbide-carbon system material thermocouple type, and method for producing the apparatus

摘要

The temperature measuring apparatus according to the present invention is of the high melting point metal carbide—carbon system material thermocouple type. According to this temperature measuring apparatus, it is possible to measure temperatures from a room temperature range to a high temperature range in excess of 2000° C. continuously, stably and with good accuracy. A constitution is preferable wherein a rod-like member formed of high melting point metal carbide is inserted into a pipe-like member with a bottom formed of carbon system material, and connected at the bottom to serve as a temperature measuring portion.
