Amplitude gain plot from a pressure sensor having a cavity before the sensing element (data from a shock tube system).

This dynamic calibration shows both resonance frequency due to pneumatic cavity and mechanical resonance of the sensing element.

Temporal response to a pressure step of a transducer used to determine the response time. (The pressure step is generated by a Fast Opening Device).

Temporal response to a pressure step of a pressure line used to determine the response time. The negative pressure step is generated by a Fast Opening Device.

Fast Opening Device can be used to generate both positive and negative steps.
