Pressure sensor with shock protection in fluid container
摘要
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 (71). One approach includes a body (300) of elastomeric material disposed on an external surface of the sensor. Another approach is a porous plug (310) in a fluid pathway (110A) leading to the sensor. Yet another approach is to provide a seal structure (320) with a labyrinth fluid path.
