Abstract:
A monitoring system includes a hydraulic accumulator including a piston movably disposed therein. At least one seal encompasses the piston. A first pressure sensor is configured to monitor pressure of a first fluid in a first chamber. A second pressure sensor is configured to monitor pressure of a second fluid in a second chamber. A first temperature sensor is disposed in the first chamber and configured to monitor the temperature of the first fluid. A second temperature sensor is disposed in the second chamber and configured to monitor the temperature of the second fluid. An electronic control unit is in communication with the sensors and programmed to in response to receiving pressure signals from the pressure sensors and temperature signals from the temperature sensors, determine a wear volume of the at least one seal; and compare the wear volume of the at least one seal to a predetermined threshold wear volume of the at least one seal to determine the remaining useful life of the hydraulic accumulator.

Claim (Index 7):
A system for wirelessly communicating health and remaining useful life of a hydraulic accumulator, comprising:\n a machine including a hydraulic system; a hydraulic circuit operatively coupled to the hydraulic system; a hydraulic accumulator fluidly coupled to the hydraulic circuit; a piston movably disposed in the hydraulic accumulator the piston separating a first chamber from a second chamber; at least one piston seal encompassing the piston; a first pressure sensor disposed in the first chamber proximate the piston seal and configured to monitor pressure of a first fluid; a second pressure sensor disposed in the second chamber proximate the piston seal and configured to monitor pressure of a second fluid:, and an electronic control unit including an algorithm, the electronic control unit in communication with the hydraulic circuit and the hydraulic accumulator, the algorithm of the electronic control unit programmed to:\n determine a wear volume of the piston seal based on pressure signals from the first and second pressure sensors proximate the piston seal, \n determine the remaining useful life of the hydraulic accumulator based on comparing a the wear volume of the at least one piston seal to a predetermined threshold wear volume of the at least one piston seal, and \n responsive to determining the remaining useful life of the hydraulic accumulator, wirelessly transmit the remaining useful life of the hydraulic accumulator,
