Title: SYSTEM, ARRANGEMENT AND METHOD FOR DETECTING DAMAGES WITH CONTINUOUS DISC FILTERS
Abstract:
The invention relates to a system for detecting damages of filter fabric (8) with continuous disc filters (1) where the system comprises of pressure sensor element (41) that is attached into a filter sector (5) so that it measures the pressure inside (11) the filter sector and is connected with a CPU (42) and a radio unit (43) that periodically transmits the measured pressure values to a receiver (R) that receives the transmitted measurements and compares the measurements using processing means (55) with previously received values and detects damages by detecting significant pressure difference.
