Series DX Wet/Wet Differential Pressure Switch
NEMA 4X Enclosure, Low Differential Set Points
The Series DX is a differential pressure switch that makes a contact output based on the differential between two pressure sources. Wetted materials of brass and flouroelastomer
are suitable for use with most gases and water based solutions. The switch
can be used for low differential pressure indication with set point on a decrease of
pressure as low as 1 psid (0.07 bar). Differential set point ranges are available from
2.5 to 75 psid (0.17 to 5.17 bar) on increasing differential pressure and 1.0 to 67
psid (0.07 to 4.62 bar) on decreasing differential pressure. Unit features a high static
pressure rating of 200 psig (13.8 bar). Weatherproof, UL type 4X, enclosure for dust
laden, outdoor, or wash-down installation environments. Externally adjustable set
point, integral mounting flange and a removable electrical terminal block for quick and
- Indicating filter condition
- Proof of flow indicator monitoring
- Proving flow through a pump
- Proving flow through a chiller
- Proving flow through a heat pump or AC unit
