Abstract (en)
[origin: EP2644076A1] The device has flow chambers e.g. dust collecting chambers (2, 10), provided with measuring points (12, 13) and connected to pressure sensors e.g. differential pressure sensors (15), which are signal-connected to a controller. The controller sends a signal when difference between pressures (P1, P2) in the flow chambers reaches a threshold value. A warning apparatus (22) obtains a control signal, and comprises an optical and/or acoustic warning element e.g. warning lamp or horn.
