Dwyer Series DX Wet/Wet Differential SPDT Pressure Switch (Models DXW-11-153-1 to DXW-11-153-4)
Product Introduction
The Dwyer Series DX Wet/Wet Differential SPDT Pressure Switch is engineered to deliver reliable contact output based on the pressure difference between two sources. With a NEMA 4X weatherproof enclosure and wetted materials like brass and fluoroelastomer, it suits most gases and water-based solutions. Ideal for low differential pressure monitoring, the switch offers set points as low as 1 psid (0.07 bar) on decreasing pressure, combined with a high static pressure rating of 200 psig (13.8 bar). Its externally adjustable design and removable terminal block ensure quick installation in dusty, outdoor, or wash-down environments.
Product Features
recision Differential Sensing:
Generates contact output based on pressure difference between two sources, suitable for low differential applications (1 psid minimum on decreasing pressure).
Set point ranges: 2.5–75 psid (increasing differential) and 1.0–67 psid (decreasing differential).
Robust Construction & Materials:
Wetted components (brass + fluoroelastomer) compatible with most gases and water-based fluids.
High static pressure rating: 200 psig (13.8 bar) for durability in high-pressure systems.
Weatherproof & Versatile Enclosure:
NEMA 4X (UL type 4X) enclosure protects against dust, water, and outdoor elements, suitable for wash-down environments.
User-Friendly Design:
Externally adjustable set points enable on-site calibration without disassembly.
Integral mounting flange and removable electrical terminal block reduce installation time.
SPDT Switching Functionality:
Single Pole Double Throw (SPDT) configuration allows flexible control for both normally open (NO) and normally closed (NC) applications.
Wide Application Scope:
Suited for HVAC, fluid systems, and industrial processes requiring differential pressure monitoring in harsh environments.
