application

Due to the use of high-temperature resistant materials as protective tubes, this series of products can work stably for a long time at temperatures ranging from 1800 to 2000 ℃. To prevent air contact around the parts during vacuum heat treatment, it is necessary to prevent air from entering the vacuum furnace. Therefore, requirements are made for the leakage rate of thermocouples used in vacuum furnaces. Usually controlled by the pressure rise rate indicator. The pressure rise rate of imported vacuum furnaces is less than 0.268Pa/h. The specialized thermocouple produced by our company adopts a solid gasification structure and a highly sealed wiring method, ensuring that the pressure rise rate of the thermocouple is less than 0.1Pa/h, which can effectively ensure that the vacuum degree inside the furnace is not damaged. Therefore, this series of products is mainly suitable for temperature measurement of various vacuum furnaces such as high-temperature vacuum and heat treatment, and can replace expensive imported products.
