Pressure change-based sensor for determining measured variable in medium, has base plate with stationary electrode, and membrane frame that is mounted on base plate

摘要

The pressure change-based sensor has a base plate (01) with a stationary electrode (09). A membrane frame (04) is mounted on the base plate. A membrane (06) has a movable electrode facing the stationary electrode. The membrane frame is provided in the region of a guide section (16) of an electrical conductor (13). A recess (17) is provided into which a sealing unit is introduced in the membrane frame. The sealing unit is formed by a ceramic glass solder (18), silver-glass solder or applying coating by low-temperature-cofired-ceramic technology.
