Abstract (en)

[origin: WO2011050983A1] The invention relates to a device for the sensor-based detection of a pressure difference occurring between a first location (5a) and a second location (5b) spaced at a distance from the first location in the flow direction in the region of a throttle (4) introduced in a working line (2) through which compressed air flows, wherein the pressure is branched at the first location (5a) in the flow direction upstream of, and at the second location (5b) in the flow direction downstream of the throttle (4), in order to feed the pressure difference via the throttle (4) on both sides to a pressure balance (6; 6') connected in parallel thereto, which provides a binary aeration and deaeration signal, in case the pressure balance (6; 6') detects a significant positive or negative pressure difference via the throttle (4), by cooperating with an electric switch unit (10; 10') of a higher-level control unit (11).
