RF2000 (RR5000D/RR5100D)
*Specifications are subject to change without prior notice.
RF2000 is a system that measures the air flow velocity to the engine radiator. The rotation frequency of a propeller sensor is measured by an infrared sensor attached to the propeller sensor. The signal from the infrared sensor is transmitted via an electrical cable to a converter for measuring the radiator air flow velocity and then converted to air flow velocity. A single converter can measure air flow velocity at 16 channels. The converter is also equipped with functions for displaying the air flow velocity and frequency, outputting an analog voltage, and performing RS-485 and CAN communication.
For RS-485 communication, up to four converters can be connected to enable simultaneous data collection on a maximum of 64 channels.
Furthermore, the dedicated measurement software TIC Wind-LV can be used to set the measurement interval and number of measurements, to collect air flow velocity data, and to output an average value for the air flow velocity. Converter settings can be changed from a computer.
For CAN communication, up to four converters can be connected to enable collection of air flow velocity data. Also, driving tests can be performed by mounting the entire system in a vehicle.
A thin and light-weight sensor with thickness of only 10 mm can be installed at a narrow space such as between a radiator and condenser.
The propeller sensor with its axis aligned parallel to the air flow direction, allows accurate measurement of the flow velocity along the perpendicular to the radiator, neglecting the flow from the other directions. Other types of sensor such as thermal type or pressure type tends to measure flow from all other directions.
The pressure loss caused by the propeller is approximately 0.1kPa(at the velocity of 20 m/s).
This is very small when compared to the pressure loss of the radiator.
Electric cables used to connect the propeller sensors and converter are flexible, resistant to low temperatures, and are easier to handle compared to optical fiber cables.
One unit of the RR5000D/RR5100D is capable of measuring 16 channels.
Four converters connected in a daisy chain can simultaneously collect data from up to 64 channels. The settings of the converters can be changed from a PC.
Four converters connected in a daisy chain can simultaneously collect data from up to 64 channels.
The communication data are transformed to air flow velocity values based on the DBC file.
