Abstract: Commercially available filter-monitoring switches suffer from problems related to over sensitivity and reliability. Accordingly, the present inventors have devised, among other things, various embodiments of filter-monitoring switches and related components, subassemblies, methods, and systems. One exemplary filter-monitoring switch includes a diaphragm operably couple to move a conductive element back and forth between a pair of fixed terminals in response to pressure differences across the diaphragm. The conductive element is mounted to an insulative pin of substantially uniform width, and the terminals include leaf contacts that constantly engage the pin or the contacts throughout normal operation of the switch, thereby reducing flexure of the contacts and effectively providing a self-cleaning and self-healing electrical switch.

Abstract: The present inventors devised, among other things, exemplary differential pressure sensors suitable for use in a wide-variety filter-monitoring applications. One exemplary sensor, which operates in any physical orientation and consist of snap-together components that require no post-assembly adjustment, includes a diaphragm assembly, a magnet, and a magnetic sensor. The diaphragm moves in response to differential pressures exceeding a predetermined threshold difference, and the magnet which is physically coupled to the diaphragm assembly moves relative to a magnetic sensor. The magnetic sensor senses movement of the magnet and produces a signal that can be correlated by a computer or other circuitry to determine whether a filter is overly clogged and thus requires replacement.
