Abstract: A sensing system for sensing degradation of a machine fluid is disclosed. The sensing system may comprise a capsule including a dissolvable element. The dissolvable element may be configured to at least partially dissolve when placed in contact with the machine fluid having an acid content indicative of degradation of the machine fluid. The sensing system may further comprise a tracer encapsulated by the capsule. The tracer may be at least partially released from the capsule when the dissolvable element at least partially dissolves.

Abstract: A sensing system for detecting degradation of a machine fluid is disclosed. The sensing system may comprise a tag having electrical contacts. The tag may be configured to transmit a wireless signal when the electrical contacts are in electrical communication. The sensing system may further comprise a dissolvable element separating the electrical contacts and obstructing electrical communication between the electrical contacts. The dissolvable element may be configured to dissolve and allow electrical communication between the electrical contacts when an acid content of the machine fluid reaches a level indicative of the degradation of the machine fluid.
