Abstract:A high temperature thermocouple testing system is developed, including a new structure of high temperature tube furnace, a temperature control module and a temperature measuring module, and the temperature stability and uniformity of the constant temperature section are experimentally studied. The temperature stability of the test system is better than ±0.25℃ in the range of 400℃ to 1000℃; The temperature uniformity of the constant temperature section with a length of 150mm is better than ±0.35℃. The experimental results show that the performance of the test system can meet the requirements of thermocouple performance test.
