Title:
PRESSURE SENSOR FOR A HERMETICALLY SEALED CONTAINER
Document Type and Number:
WIPO Patent Application WO/2010/096156
Kind Code:
A3
Abstract:
A pressure sensor (74) is provided for a container (10) having a hermetically sealed internal chamber (42). The pressure sensor (74) includes a support member (26) having a membrane side (78) and an electrical contact (96) extending along the membrane side (78). The support member (26) is configured to be held by the container (10) such that at least a portion of the support side (26) is exposed to the internal chamber (42) of the container (10). The pressure sensor (74) also includes a membrane (90) having a chamber side (102) and an opposite support side (104). The membrane (90) is held by the support member (26) such that the chamber side (102) is configured to be exposed to the internal chamber (42) and the support side (104) is configured to be isolated from the internal chamber (42). A pressure differential across the chamber side (102) and the support side (104) of the membrane (90) deflects the membrane (90) into and out of engagement with the electrical contact (96) of the support member (26).
