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”).
