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.
Claims20
A system, comprising:
- at least one pressure sensor which monitors a force applied by a filter on a 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.
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;
- 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.

A method of measuring a condition of a filter, comprising:
- measuring a force applied by a filter on a 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.
