This disclosure provides systems, methods and apparatus for glass-encapsulated pressure sensors. In one aspect, a glass-encapsulated pressure sensor may include a glass substrate, an electromechanical pressure sensor, an integrated circuit device, and a cover glass. The cover glass may be bonded to the glass substrate with an adhesive, such as epoxy, glass frit, or a metal bond ring. The cover glass may have any of a number of configurations. In some configurations, the cover glass may partially define a port for the electromechanical pressure sensor at an edge of the glass-encapsulated pressure sensor. In some configurations, the cover glass may form a cavity to accommodate the integrated circuit device that is separate from a cavity that accommodates the electromechanical pressure sensor. |
