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 radiator and 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 from the other directions. Other types of sensor such as thermal type or pressure type tends to measure flow from all other directions.

• Low pressure loss

  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.

• Connected to electric cables

  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.

• More channels

  One unit of the RR5000D/RR5100D is capable of measuring 16 channels.

• 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 are transformed to air flow velocity values based on the DBC file.
