About the Air Flow Transmitter
The Air Flow Transmitter is an airflow transducer which may be used for control,
monitoring and regulation of airflow speed in fresh air and ventilation units etc.
The transmitter registers airflow speed according to a thermal principle based on
the fact that the cooling action of air increases with airspeed. The action is
measured and converted to a 4 to 20 ma or a 0 to 10V signal corresponding to
airflow speeds from 0.5 to 8 m/s (100 to 1575 ft/min) or 0.5 to 16 m/s (100 to 3150
ft/min).
The micro-processor based electronics provides an output signal that is linear and
corrected for temperature changes. If a standard analog instrument is connected the
airflow speed and temperature can be read remotely.
The transmitter has a separate 0 to 10 Vdc output signal for measurement of the air
temperature 0 to 50ºC (32 to 122°F).
IMPORTANT
Transmitter must not be mounted near elbows , damper vanes or
other restrictions that may cause turbulent air flow. Always install
in a straight section of duct.
