Continuous monitoring of filter components can be achieved by installing a differential pressure sensor at the entrance of the filter to observe pressure changes. Filters are used in numerous industries and applications all around us. Automotive “air induction system” (AIS) filters protect the engine and the mass airflow sensors (MAFS) against contaminants, while cabin air filters provide clean and healthy air for the driver and passengers. CMP slurry dispense systems may. The BCI series from Bühler Technologies, short for "Bühler Clogging Indicator", monitors the differential pressure in line filters and generates electrical output signals proportional to the decreasing filter capacity. Many of the BCI variants are available with IO-Link.
