FPS - Fluid Property Sensor

The FPS is a novel fluid property sensor that will directly and simultaneously measure the viscosity, density, dielectric constant and temperature of fluids. Relying on patented tuning fork technology, the sensor monitors the direct and dynamic relationship between multiple physical properties to determine the quality, condition and contaminant loading of fluids such as engine oil, fuel, transmission and brake fluid, hydraulic, gears oils, refrigerants and solvents.
The multi-parametric analysis capability improves fluid characterization algorithms. The FPS provides in-line monitoring of fluids for a wide range of OEM and aftermarket installations including fluid reservoirs, process lines and pressurized high flow conduits (e.g., engine oil gallery) for applications that include on and off highway vehicles, HVACandR, compressors, industrial equipment and turbines. A universal digital CAN J1939 compliant protocol provides easy to connect interface to main Host controller. A simple 4 pin connector allows for cost effective mounting options.
Important note:
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 aging of the oil can start and hence the calibrated reference is not accurate. When a 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.
Advantages
• Continuously measurement of important fluid properties
• Early detection of fluid aging
• No up-front calibration required
• On board processor with real-time data analysis with 5, 10 or 24 volts supply
