PROBLEMS OF DYNAMIC PRESSURE MEASUREMENT

Andreas Hebestreit

Abstract

Pressure sensor elements are in general able to swing. Some data sheets tell the damping constant and the natural frequency. These dynamic characteristics influence the measuring values in case the pressure alters very fast. If the pressure changes with frequencies which are in the near of the resonance frequency of the sensor large measuring deviations will occur. But we did not learned yet how much the damping constant and the natural frequency of the sensor will be, when it is mounted and has contact with the fluid.
