Spherical piezoceramic sensors for measuring shock-wave parameters

摘要

The results of the development and the main performance characteristics of spherical piezoceramic sensors of four sizes (with diameters of the sensitive elements of 5, 10, 15, and 32 mm), which are intended for measuring the parameters of pulse pressures behind the front of air shock waves in the range of 0.0001-2.0 MPa, are described. Examples of the practical use of spherical piezoceramic sensors for measuring the parameters of air shock waves in shock tubes and explosive experiments are presented.
