In the aerospace field, dry block calibrators are of great significance for the calibration of temperature sensors (including thermocouples and platinum resistance, etc.). In the manufacturing and testing process of aircraft engines, accurate temperature measurement is the key to ensuring engine performance and safety. The temperature sensors calibrated by the dry block calibrator can accurately monitor the temperature changes in various parts of the engine, providing data support for the optimization design and fault diagnosis of the engine. In the thermal control system of spacecraft, the temperature sensors calibrated by the dry block calibrator help to accurately control the internal temperature environment of the spacecraft, ensure the normal operation of various instruments and equipment on the spacecraft, and ensure the smooth progress of aerospace missions.
