Dwyer Instruments 1823-0 Pressure Switch
The Dwyer Instruments 1823-0 Pressure Switch is a compact, high-performance differential pressure switch designed for reliable monitoring of air and non-combustible gases in industrial HVACR systems. Built for veteran technicians who demand precision in low-pressure applications, this 1800 Series unit features an adjustable set point range of 0.15" w.c. to 0.5" w.c. with a tight 0.06" approximate deadband. The 1823-0 utilizes a vertically mounted diaphragm and a snap-action SPDT switch, providing consistent repeatability of ±2% across its operating life. Its unique design includes a 1/8" female NPT connection and a set point adjustment screw conveniently located inside the mounting spud, allowing for streamlined panel mounting where adjustments are accessible from the opposite side. With a 10 psig pressure limit and a rugged metallic housing, this low pressure cutout switch is an essential component for fan proving, filter monitoring, and general industrial duct pressure control.
- Precise Set Point Control: Field-adjustable range from 0.15 to 0.5 inches of water column ensures accurate pressure switch calibration for sensitive airflow requirements.
- Versatile Electrical Compatibility: Features SPDT contacts rated for 15A at 120-480 VAC, suitable for various control circuit configurations.
- Compact Industrial Design: Small footprint allows for installation in tight mechanical spaces without sacrificing technical durability or performance.
- Standardized Plumbing: Equipped with dual 1/8" NPT process connections for seamless integration into existing pneumatic lines.
Common Questions
What is the proper mounting orientation for the Dwyer 1823-0?
Technicians should always mount this switch with the diaphragm in a vertical plane. Orientation is critical for maintaining the calibrated set point and ensuring the 2% repeatability rating holds true under field conditions.
Can this switch be used for combustible gas applications?
No. The 1823-0 is strictly engineered for air and non-combustible gases. Using this unit in environments with flammable gases poses a significant safety risk and ignores the manufacturer's specified service limits.
How do I adjust the pressure set point?
Adjustment is performed via the slotted screw located inside the mounting spud. This internal placement prevents accidental tampering while remaining easily accessible for routine maintenance and system balancing.
