Summary:A filter (42) for a machine fluid (12) comprises a tag (54) having electrical contacts (60). The tag (54) may be configured to transmit a wireless signal (56) when the electrical contacts (60) are in electrical communication. The sensing system (52) may further comprise a dissolvable element (62) separating the electrical contacts (60) and obstructing electrical communication between the electrical contacts (60). The dissolvable element (62) may be configured to dissolve and allow electrical communication between the electrical contacts (60) when an acid content of the machine fluid (12) reaches a level indicative of the degradation of the machine fluid (12).
