The aerospace field has extremely high standards for the reliability and accuracy of equipment. Temperature sensors, as important components for monitoring the temperature of key parts of aircraft, their calibration accuracy and reliability are of crucial importance. Dry-block calibrators play a key role in the calibration of temperature sensors in aerospace. It can meet the requirements of wide temperature range, high stability and high-precision calibration of aerospace temperature sensors. Whether it is a high-temperature sensor used for engine temperature monitoring or a normal-temperature sensor used for temperature monitoring in the avionics equipment compartment, dry-block calibrators can provide a matching calibration environment. During the research, development, production and maintenance of aircraft, regularly using dry-block calibrators to calibrate temperature sensors helps to ensure that the aircraft can accurately obtain temperature data under various extreme environmental conditions, such as low temperature at high altitude and high temperature of the engine, providing a reliable basis for the safe flight, system control and fault diagnosis of the aircraft and ensuring the smooth progress of aerospace missions.
