Recent research and development has produced a new onboard data digitalization solution for hydraulic pumps. Currently applied to field-proven, variable-displacement piston pumps, the system is equipped with embedded electronics and sensor technology, able to measure, use and transmit hydraulic performance information. Principles of operation are described, along with features such as predictive maintenance calculation, detection of imminent failure through anomalous conditions, analysis of duty cycle severity, and data conditioning and transmission capability supporting cloud-based telematics. Additionally, pending technology in contamination sensing and fluid condition monitoring will be previewed.
