Throughout the long history of industrial development, pressure gauge calibration has undergone a rich process of historical evolution. In the early days, calibration methods were rather rudimentary, mainly relying on experienced craftsmen who used simple reference tools and their long-accumulated practical experience to judge the accuracy of pressure gauges. For example, in the factories during the steam age, craftsmen would connect a steam container with a known pressure to the pressure gauge to be calibrated and make rough adjustments by comparing the reading differences of the pressure gauge under the standard pressure of the container.
With the progress of science and technology, in the 20th century, standard pressure generators based on mechanical principles emerged, which greatly improved the precision and repeatability of calibration. In modern times, the rapid development of electronic and computer technologies has brought revolutionary changes to pressure gauge calibration. Digital calibration equipment can accurately generate and measure pressure, and computer software can quickly analyze and process calibration data, realizing automated calibration and error correction, which has significantly enhanced the calibration efficiency and accuracy, meeting the growing demand for high-precision pressure measurement in modern industry.
