DEVICE AND METHOD FOR DYNAMIC CALIBRATION OF PRESSURE SENSORS

摘要

FIELD: physics.;SUBSTANCE: invention is based on the invention relating to the pressure sensors dynamic calibration device and method, wherein by the pistonphone principle pressure acting on the pressure sensor is compared with the corresponding preset parameter, on the basis of which calibration value c is determined, task of solution creation lies, which would provide primary calibration of dynamic behaviour of pressure sensor. This problem is solved due to that the device is statically determined only due to the corresponding connection of the housing to the actuator and the actuator to the piston, and piston is sealed in cylinder from ambient atmosphere by means of seal and movably located in seal, and pressure value is calculated corresponding to actual value.;EFFECT: technical result is creation of method and device for primary dynamic calibration of pressure sensors.;18 cl, 10 dwg
