PRESSURE SENSITIVE DEVICE FOR FLOW DETECTION |
摘要 |
A pressure sensitive device includes a ring having a central axis, first side and second side. The ring includes a dielectric portion parallel to the central axis and between the first and second sides. A flexible membrane is connected to a periphery of the ring on the first side, the flexible membrane including a conductive portion. A perforated membrane is connected to a periphery of the ring on the second side. The perforated membrane is spaced apart and electrically isolated from the flexible membrane by the ring below a threshold pressure differential across the pressure sensitive device. The perforated membrane includes an opening therethrough and a conductive portion facing and corresponding to the conductive portion of the flexible membrane such that a threshold pressure differential across the pressure sensitive device causes deflection between the conductive portions of the flexible membrane and the perforated membrane to change an electrical property. |

1. A pressure sensitive device, comprising:
a ring having a central axis, a first side and a second side, the ring including a dielectric portion parallel to the central axis and between the first side and the second side; a flexible membrane connected to a periphery of the ring on the first side, the flexible membrane including a conductive portion; and a perforated membrane connected to a periphery of the ring on the second side, the perforated membrane being spaced apart and electrically isolated from the flexible membrane by the ring below a threshold pressure differential across the pressure sensitive device, the perforated membrane including an opening therethrough and a conductive portion facing and corresponding to the conductive portion of the flexible membrane such that a threshold pressure differential across the pressure sensitive device causes deflection between the conductive portions of the flexible membrane and the perforated membrane to change an electrical property. |
