Aspects herein include filtration systems with multitiered data exchange capabilities. In an embodiment, a filtration system with multitiered data exchange capabilities is included. The system can include a first data communication tier including a filter element, the filter element storing data, and a first sensor. The system can include a second data communication tier including a reader device in communication with the first sensor. The system can include a third data communication tier including an engine control unit (ECU) in communication with the reader device, wherein the ECU stores data. The second data communication tier receives data from the first data communication tier and the third data communication tier. The second data communication tier executes operations on the received data to create a processed data set. Further, the second data communication tier sends the processed data set to the third data communication tier. Other embodiments are also included herein.

Filtration systems with multitiered data exchange capabilities

An air cleaner assembly with a restriction indicator includes a housing having an exterior surface around an interior volume. The housing includes a bore extending through a portion of the exterior surface of the housing surrounded by a bore wall protruding from the portion of the exterior surface. A receptacle wall of the housing is disposed around the bore wall and is radially spaced from the bore wall to form a channel between the bore wall and the receptacle wall. A restriction indicator measures a restriction in the interior volume and displays an indication of the restriction. The restriction indicator includes a stem that is at least partially insertable into the bore that engages an inner surface of the bore wall. One or more tabs of the restriction indicator are at least partially insertable in the channel and removably couple to the receptacle wall.

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.
