Device and method for dynamically calibrating pressure sensors

摘要

The present invention relates to a device and method for dynamically calibrating pressure sensors. The pressure acting on the pressure sensor is compared by the device to the corresponding desired parameter according to the piston phone principle, from which a calibration value c is determined. It is an object of the present invention to provide a method and a solution that enables a primary calibration of the dynamic ratio of a pressure sensor to be carried out. This is achieved by the fact that the device is statically determined only by the connection of the housing and the actuator and the connection of the actuator and the piston, respectively, the piston is sealed in the cylinder against the ambient atmosphere by a seal, arranged movably within the seal and , The change in pressure corresponding to the actual value is calculated.
