Abstract
A pressure sensor is provided for a container having a hermetically sealed internal chamber. The pressure sensor includes a support member having a membrane side and an electrical contact extending along the membrane side. The support member is configured to be held by the container such that at least a portion of the support side is exposed to the internal chamber of the container. The pressure sensor also includes a membrane having a chamber side and an opposite support side. The membrane is held by the support member such that the chamber side is configured to be exposed to the internal chamber and the support side is configured to be isolated from the internal chamber. A pressure differential across the chamber side and the support side of the membrane deflects the membrane into and out of engagement with the electrical contact of the support member.
