Dynamic Response of Pressure Measuring Systems

摘要

The measurement of time varying pressures is limited when a pressure transmissionline must be used. The type of pressure transducer can further limit the speed at which pressure changes can be observed. This report investigates these limitations by subjecting commonly used pressure line tubing and pressure transducers to a step pressure input. By spectrally analysing the response to this step input a frequency response for the system can be determined.... Pressure measurement, Time lag, Pressure gauges, Dynamic response, Reaction time.
