PRODUCT DESCRIPTION
The DPFS sensors are designed to sense differential
pressure in the inlet section of VAV (Variable Air
Volume) terminal units and fan terminal units. They
can also be used to sense differential pressure at
other locations in the main or branch duct systems.
The differential pressure read between the high “H”
port and the low “L” port can be used to determine
the air flow. Models offer up to nine sensing points
and sensing lengths of 8.02 to 55.01 cm (3-5/32 to
21-21/32”) to accommodate box size diameters of
10 to 76 cm (4 to 30”).
