A Novel Ceramic Thermocouple Used in High-Temperature Measurement

Article Preview

Abstract:

MoSi2 and SiC ceramics were prepared by traditional powder metallurgy method. A novel ceramic thermocouple (CTC) used in the high temperature and high corrosion environment was assembled by SiC as the cathode and MoSi2 as the anode. The thermo-emf of CTC was tested from 25 °C to 1600 °C in air. The results show that there is a simple relationship between the thermo-emf of CTC and the temperature. By holding temperature for 70 h at 1500 °C, the deviation of thermo-emf is ±0.37%, and better than 0.75% which is the criteria of industry thermocouple. And also the response characteristics of CTC were analyzed.
