I. Overview
This system is based on the characteristics of the “Twelfth Five-Year Plan†for the cultivation of talents, with the goal of cultivating application-oriented and skilled talents; combining the needs of teaching and training with the actual equipment used in the factory, and adjusting the instrument to new knowledge, new skills and new detection Means, applied to school automation instrument training device. Digitally controlled electric pressure making, used with digital standard pressure gauges, can replace some piston pressure inspection systems, to achieve the general pressure gauge, precision pressure gauge, pressure transmitter, differential pressure transmitter, pressure switch and other instruments Verification work; it is an ideal calibration device for verifying pressure instruments in petroleum, chemical, electric power, metallurgy, national defense, and measurement departments, and is also a necessary equipment for school automation and instrumentation related modern instrument detection training.
Second, the system composition
The entire calibration system is composed of: electric pressure-making test bench, digital standard pressure calibrator, pointer pressure gauge, transmitter mounting stand, pipeline connection joints and accessories.
