OMEGA’s state-of-the-art wind tunnel is
designed to give a highly uniform flow
rate over a 152 mm (6") test section. A
powerful 12 amp motor with variable
speed from 0 to 10,000 RPM is
adjustable to give a particular flowrate
by a precise motor control unit. Each
wind tunnel is supplied with an NIST
traceable certificate.
The uniform flowrate is determined by
monitoring a highly repeatable
differential pressure sensor which has
been calibrated to each individual wind
tunnel as a system. Each wind tunnel is
supplied with two restrictive plates for
achieving optimum low flowrates. The
established differential pressure
measurements versus flowrates are
listed from 25 to 9000 FPM. Calibration
sheets are included, which makes
calibrating different flow sensors simple.
The differential pressure measurement
used to establish known flowrates will
be affected by barometric pressure and
temperature conditions during testing.
Depending on the probe being calibrated,
humidity may also be a factor.
OMEGA’s enhanced wind tunnel package
is an environmental monitoring system
that measures barometric pressure,
room temperature, humidity and
differential pressure. By monitoring
room conditions, standard differential
pressures can be converted to actual
differential pressure readings to ensure
accurate flowrates.
For testing different probes, a 1.2 NPT
connection is available. An assortment
of compression fittings is provided to
help mount the probe under calibration.
High Performance Package:
Same differential system as standard
model, plus HX97-A temperature and
humidity sensor, PX02C1-16A5T
barometric sensor, PSS-D15B power
supply, three DP25-E panel meters, and
one DP41B-S panel meter. All
equipment is enclosed in a heavy duty,
air cooled, benchtop metal case. All
4 meters have 0 to 10 Vdc analog
outputs.
Wind tunnels come complete with 1.8, 3.16,
1.4 and 3.8" brass compression fittings with
PTFE ferrules, two 1.52 m (5') lengths of
silicone tubing, operatorfs manual with
NIST calibration data and pressure
sensor with benchtop meter.
The intake air flow passage to this
precise wind tunnel is a fiberglassconstructed
baffle. The honeycomb
baffle design insures constant and
evenly distributed air intake. The design
minimizes turbulent air flow created by
movement in front of the intake. The
rear portion of
the intake
baffle has a
profile design
that keeps the
stream
uniform, while
decreasing the
area to a
101.6 x
101.6 mm
(4 x 4")
cross- section.
The test
chamber is
101.6 x 101.6
x 152 mm
(4 x 4 x 6")
and is constructed of clear, thick-wall
plastic for easy viewing. In back
of this test section, the motor pulls the
air through the wind tunnel. The motor
and intake profiles utilize fiberglass
construction, which minimizes airflow
distortion.
A monitoring package keeps
track of ambient conditions as well as
the precise differential pressure
measurement. The monitoring sensors
and
instruments
are all
packaged
inside a single
powerful
housing. Each
sensor has an
analog output
for use with a
strip chart
recorder or
computer data
logging
system.
Humidity,
temperature
and barometric
sensors are
enclosed in the benchtop case for
monitoring atmospheric conditions
which can influence the exact air speed.
The differential pressure cell is
connected to the wind tunnel via silicone.
