1. A system, comprising:
- at least one pressure sensor which monitors a force applied by a filter on a filter housing, wherein the at least one pressure sensor and the filter are supported by the filter housing and the least one pressure sensor is provided between the filter and the filter housing; and
a control system which provides notification to a user when the force measured by the at least one pressure sensor exceeds a predetermined threshold value.

Abstract
Systems and methods for monitoring quality of filters within a filtering system are disclosed. The system includes at least one pressure sensor which monitors a force applied by a filter on a filter housing. The system further includes a control system which provides notification to a user when the force measured by the at least one pressure sensor exceeds a predetermined threshold value.

12. A system, comprising:
-
at least two piezoelectric pressure sensors mounted between a filter and a filter housing, the at least two piezoelectric pressure sensors sense an increased force applied by the filter on the filter housing during use, wherein the filter housing supports the at least two piezoelectric pressure sensors and the filter, and the at least two piezoelectric pressure sensors are provided between the filter housing and the filter; and a control system connected to the at least two piezoelectric pressure sensors, the control system; determining a calculated reading of the at least two piezoelectric pressure sensors; correlating the calculated reading to a predetermined value, and providing a notification to a user when the correlated calculated reading is above the predetermined value. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method of measuring a condition of a filter, comprising:
-
measuring a force applied by a filter on a filter housing by at least one pressure sensor, wherein the filter housing supports the at least one pressure sensor and the filter, and the at least one pressure sensor is provided between the filter and the filter housing; correlating the measured force with a condition of a filter; and providing a notification to a user that the condition of the filter includes a blockage, when the measured force is above a threshold value. - View Dependent Claims (21)
