Abstract
An automatically compensatable device for measuring a pressure difference includes a housing (4) with pressure feed passages (20; 23), a sensor element (6) with electrical connections (13) which is arranged in the housing (4), a valve (7) which is integrated in the housing (4) and which has a closure portion (32) by which a pressure difference across the sensor element (6) can be short-circuited and actuator means (34, 31) arranged in the housing (4) for triggering a movement of the closure portion (32). The automatically compensatable device permits quiet operation.
