Synchronization of lubricant system service

A method comprising:

• collecting, by a sensor input circuit of a controller, a viscosity feedback signal from a viscosity sensor indicating a viscosity of a fluid and a dielectric feedback signal from a dielectric sensor indicating a dielectric constant of the fluid for a time interval;
• collecting, by the sensor input circuit of the controller, a pressure signal from a pressure sensing assembly indicating a pressure differential drop across a filter element of a lubricant filtration system;
• determining, by a service interval circuit of the controller, that at least one of the fluid or the filter element requires replacement based at least in part on the dielectric constant, the viscosity of the fluid, or the pressure differential;
• responsive to determining that the filter element should be replaced, determining, by the service interval circuit, that the fluid should be replaced based on a remaining useful life of the fluid being less than a fluid expected useful life threshold, wherein the fluid expected useful life threshold is greater than a portion of an expected useful life of the fluid;
• responsive to determining that the fluid should be replaced, determining, by the service interval circuit, that the filter should be replaced based on a remaining useful life of the filter being less than a filter expected useful life threshold, wherein the filter expected useful life threshold is greater than a portion of an expected useful life of the filter;
• and
• initiating, by the controller, a service alert to an operator device in response to determining that at least one of the fluid or the filter element require replacement.

A controller for a fluid delivery system, comprising:

• a memory;
• a processor configured to execute instructions stored in the memory;
• a sensor input circuit configured to receive a pressure signal indicating a pressure drop across a filter element, a viscosity feedback signal indicating a viscosity index of a fluid, and a dielectric feedback signal indicating a dielectric constant of the fluid;
• a service interval circuit configured to:
• dynamically determine that at least one of the filter element should be replaced based at least in part on the pressure or the fluid should be replaced based at least in part on the viscosity feedback signal and the dielectric feedback signal;
• responsive to determining that the filter element should be replaced, determine that the fluid should be replaced based on a remaining useful life of the fluid being less than a fluid expected useful life threshold, wherein the fluid expected useful life threshold is greater than a portion of an expected useful life of the fluid;
• responsive to determining that the fluid should be replaced, determine that the filter should be replaced based on a remaining useful life of the filter being less than a filter expected useful life threshold, wherein the filter expected useful life threshold is greater than a portion of an expected useful life of the filter;
• and
• an operator input/output circuit configured to indicate to a user that at least one of the filter element and the fluid should be replaced in response to the service interval circuit determining that at least one of the filter element and the fluid should be replaced.
