Fluid condition sensor and maintenance systems and methods

A fluid condition sensor method comprising:

• monitoring, by one or more fluid condition sensors, one or more parameters of fluid in a fluid power system;
• communicating the one or more parameters of the fluid in the fluid power system to a gateway via a data communications protocol interface, wherein the data communications protocol interface polls the one or more fluid condition sensors at a frequency that increases when non-nominal sensor readings are received;
• employing, by the gateway, a data communications protocol interface master function, a cloud computing interface module, and program instructions to:
• periodically sampling fluid condition sensor readings via the data communications protocol interface;
• formatting the readings;
• sending the readings to a cloud computing message queuing telemetry transport broker for processing by a cloud monitoring system.

A method for providing servicing for a fluid power system, comprising:

• cleaning varnish off of surfaces in the fluid power system;
• installing a fluid condition sensor system, comprising:
• one or more fluid condition sensors monitoring one or more operating parameters of fluid in the fluid power system;
• and
• an industrial internet of things a gateway communicatively coupled to the one or more fluid condition sensors, the industrial internet of things gateway communicating the one or more operating parameters of the fluid in the fluid power system, via a programmable logic controller data communications protocol interface, the industrial internet of things gateway comprising:
• a programmable logic controller data communications protocol interface master function;
• a cloud computing interface module;
• and
• program instructions, that when executed by the industrial internet of things gateway, causes the industrial internet of things gateway to periodically sample fluid condition sensor readings via the programmable logic controller data communications protocol interface, format the readings, and send the readings to a cloud computing message queuing telemetry transport broker for processing by a cloud monitoring system;
• issuing or obtaining a warranty, guarantee and/or service contract covering repair and/or replacement of named components that breakdown due to failure of the fluid power system;
• providing, by the cloud monitoring system, monitoring of the one or more operating parameters of fluid in the fluid power system;
• providing, by machine learning in the program instructions, predictions of fluid quality;
• providing, by the machine learning, predictions of buildup of varnish in the fluid power system;
• applying, by a scoring algorithm, machine learning to predict fluid power system failure;
• and
• using the predictions of fluid quality, the predictions of buildup of varnish in the fluid power system and/or a prediction of fluid power system failure, by the program instructions, to create a work ticket related to the fluid power system.
