1/5
• Fully integrated, stand-alone module
combines sensor and processing
electronics
• Accurate, repeatable temperature, viscosity,
density and dielectric constant
• Factory calibrated with NIST traceable fluids
• Digital output as per J1939, CAN2.0B standard
or CAN2.0A featuring high-resolution
param e te r reading s
DESCRIPTION
The FPS2800B12C4 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 and
gear 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, HVAC&R, 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.
FEATURES APPLICATIONS
• Rugged construction for high pressure and high
flow environments
• Proprietary corrosion and contaminant resistant
coating for wetted parts
• On-board microprocessor for real-time data
analysis with 12 - 24 volts supply
• Highly reliable and long term stability
•
On and Off Highway Vehicles
• HVAC&R
• Compressors
• Industrial Equipments
• Turbines
