DETERMINATION OF PRESSURE TRANSDUCER SENSITIVITY TO HIGH FREQUENCY VIBRATION

S. Downes, A. Knott, I. Robinson

Abstract

This paper reports on an investigation into the sensitivity of one type of piezoelectric pressure transducer to the acceleration of its support mount, when located in the end wall of a shock tube and subjected to a very fast pressure step. Support mounts of different materials are used, together with laser vibrometry measurements of the back face of the mount, in an attempt to separate the part of the signal due to the acceleration from that due to the pressure step.
