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”).
