Radiator air flow measurement system

RF2000

RR5000D/RR5100D Converter for Infrared Sensors
OUTLINE
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 toa converter for measuring the radiator air flow velocity and thenconverted to air flow velocity. A single converter can measure
air flow velocity at 16 channels. The converter is also equippedwith functions for displaying the air flow velocity and frequency,
outputting an analog voltage, and performing RS-485 and CANcommunication.
For RS-485 communication, up to four converters can be connected
to enable simultaneous data collection on a ma ximum of 64
channels. Furthermore, the dedicated measurement software TIC
Wind-LV can be used to set the measurement interval and numberof measurements, to collect air flow velocity data, and to output anaverage value for the air flow velocity. Converter settings can bechanged from a computer.

FEATURES❑ Compact sensors
A thin and light-weight sensor with thickness of only 10 mm
can be installed at a narrow space such as between a radiatorand condenser.
❑ Accurate directional measurement
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 fromthe other directions. Other types of sensor such as thermal type

Settingfunction
AnalogoutputAccuracy

The pressure loss caused by the propeller is approximately 0.1
kPa (at the velocity of 20 m/s). This is very small when comparedto the pressure loss of the radiator.
❑ Connected to electric cables
Electric cables used to connect the propeller sensors andconverter are flexible, resistant to low temperatures, and areeasier to handle compared to optical fiber cables.
❑ More channels
One unit of the RR5000D/RR5100D is capable of measuring 16channels.
❑ RS-485
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.
❑ CAN communication
Four converters connected in a daisy chain can simultaneously
collect data from up to 64 channels. The communication data aretransformed to air flow velocity values based on the DBC file.
