[0002] Early pressure pulsation detection equipment was mainly based on mechanical sensors, such as pressure diaphragms and bellows. These devices can measure instantaneous changes in pressure, but have low accuracy and are easily affected by environmental factors. Data recording mainly relies on mechanical recorders, and data processing and analysis are relatively difficult. With the development of electronic technology, pressure sensors are gradually replaced by piezoelectric sensors and capacitive sensors. These sensors have higher accuracy and stability. Data acquisition systems begin to use analog electronic circuits. Data can be preliminarily analyzed through simple analog signal processing equipment. The pressure pulsation data simulation detection equipment composition structure includes a pressure sensor, a data acquisition module, a signal conditioning module, a data processing and analysis module, and a data display and recording module.
