Pressure Sensor M

Piezoelectric Transducers for High Frequency Measurements

The piezoelectric PVDF Pressure Gauge series M is the state of the art device for measuring high frequency pressure changes with rise times of only a few nanoseconds in gases and liquids. The transducer is based on piezoelectric pvdf. It is recommended for measuring blast waves, shock waves in shock tube experiments or other dynamic pressures. The gauge is nearly free from vibrations.

All sensor elements are protected by an elastic resin for thermal protection.
