ABSTRACT:
Techniques are disclosed for improving pressure sensor shock robustness in fluid containment devices by providing a mechanical filter configured to prevent high-frequency pressure shocks from damaging the pressure sensor. One approach includes a body of elastomeric material disposed on an external surface of the sensor. Another approach is a porous plug in a fluid pathway leading to the sensor. Yet another approach is to provide a seal structure with a labyrinth fluid path.
