With the continuous progress of science and technology, new pressure gauge calibration technologies have emerged and are gradually being applied. For example, an intelligent pressure gauge calibration system based on digital sensors and microprocessors can realize functions such as automatic data acquisition, real-time error calculation and correction, and remote monitoring. In this system, the sensor converts the pressure signal into a digital signal and then directly transmits it to the microprocessor. The microprocessor quickly processes the data according to the built-in calibration algorithm and can automatically adjust according to the preset standard, greatly improving the calibration efficiency and accuracy. In addition, laser interferometry is also applied to high-precision pressure gauge calibration. It uses the high coherence and stability of the laser to accurately measure the small displacement change caused by pressure, thereby calculating the pressure value, providing a new solution for the calibration of ultra-high-precision pressure gauges. The exploration and application of these new technologies have brought new vitality and development directions to the field of pressure gauge calibration, and are expected to further improve the accuracy and reliability of industrial pressure measurement in the future.
