Total Health Management of Fluid Power and Lubrication Systems
A unique solution for continuous monitoring of fluid condition.
Improving uptime of equipment and lowering the cost of ownership.
A NEW addition to Parker Hannifin’s Condition Monitoring range – the Fluid Property Sensor has been designed especially for mobile applications calling for cost effective but quality verification of the hydraulic fluid condition.
High cost of ownership is caused by the ageing of hydraulic fluids, which accelerates the wear of system components. Modern systems are designed to operate at a high level of efficiency and reduced consumption. As a consequence, more frequent fluctuations of pressure, flow, load and temperature are present in the system which typically shortens the life time of hydraulic fluids. Catalytic processes can be accelerated with the presence of low concentrations of moisture and wear elements like Fe and Cu in the oil. Varnish can be created in the system due to this ageing process, shortening the life time of system components and reducing the system efficiency.
Lower cost of ownership can be realised when hydraulic fluids are replaced in time, based on the principle of continuous measurement of the condition.
The FPS is a novel fluid property sensor that directly and simultaneously measures the viscosity, density, dielectric constant and temperature of fluids.
The quality of hydraulic fluids is determined by monitoring the direct and dynamic relationship between multiple fluid properties.
The FPS provides in-line monitoring of fluids for a wide range of first fit OEM applications and upgrade of installations.
A universal CAN J1939 protocol provides an easy to connect interface to the main system controller.
A major advantage is that the Parker FPS does not use a “fingerprint” principle. Sensors using a “fingerprint” principle require up-front calibration in the fluid type subject to future analysis. This calibration can take up to 200 hours, during which time the ageing of the oil can start and hence the calibrated reference is not accurate. When different oil is applied, sensors using the “fingerprint” principle require new calibration. Parker’s PFS sensor directly measures the important fluid properties without the need for calibration in-advance.
