Dwyer Instruments now offers series PAFS-1000 averaging airflow sensors
for sensing differential pressure in the inlet section of variable air
volume terminal units and fan terminal units, or to sense differential
pressure at other locations in the main or branch duct systems.
The "H" port on these airflow sensors senses total pressure and the "L"
port senses static pressure. The difference between these signals is the
differential, or velocity pressure.
Models PAFS-1002 to PAFS-1005 of these sensors can be supplied with up
to four sensing points and lengths of 3-5/32" to 9-29/32" (8.02 to 25.26
cm), to accommodate box size diameters of 4" to 16" (10.16 to 40.64 cm)
are available.
For models PAFS-1006 to PAFS -1011, up to 10 sensing points and lengths
from 12-1/2" to 23-29/32" (31.75 to 60.72 cm) are available to
accommodate appropriately sized duct dimensions.
