Air Flow Transmitter

Catalog Number 1414-IFZ35FGDAA

Before you Install

In order for the transmitter to operate correctly all the information supplied in this
document must be followed.

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.

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 User Information

Solid state equipment has operational characteristics differing from those of electromechanical equipment.
Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication
SGI-1.1 available from your local Rockwell Automation sales office or online at
http://www.literature.rockwellautomation.com) describes some important differences between solid state
equipment and hard-wired electromechanical devices. Because of this difference, and also because of the
wide variety of uses for solid state equipment, all persons responsible for applying this equipment must
satisfy themselves that each intended application of this equipment is acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages
resulting from the use or application of this equipment.
