| description | A capacitive differential pressure sensor is described which has a simple configuration, and which provides reliable measuring results even in corrosive measuring environments. The sensor element for capacitively measuring differential pressure includes a sensor diaphragm which is implemented in a layered configuration on a semiconductor substrate and spans a cavern. A pressure connection opens into the cavern. The sensor element also includes a measuring capacitor which has a movable electrode on the sensor diaphragm, and a stationary counter electrode which is situated on the base of the cavern, opposite from the movable electrode. According to the sensor, the cavern is filled with a dielectric fluid. |
