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 0.1
kPa (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.
