Dwyer Instruments 1823-20 Pressure Switch
The Dwyer Instruments 1823-20 Pressure Switch is a low differential pressure switch engineered for precision in general industrial service and mechanical equipment control. Designed for air and non-combustible gases, this model features a 3 to 22 inch w.c. range with a calibrated SPDT snap-acting switch for reliable set point management. The unit provides a 2% repeatability across the full scale, ensuring consistent performance in critical monitoring tasks. Its rugged metallic housing includes 1/8" female NPT connections and is rated for a 10 psig pressure limit. A key advantage for contractors is the set point adjustment screw located inside the mounting stud, allowing for effortless calibration from the opposite side of a wall or panel without dismantling the enclosure. Whether used for filter monitoring or ventilator control, this industrial pressure switch delivers the reliability required in professional HVACR environments. The unit is UL and CSA listed, as well as FM approved, meeting stringent safety standards for North American installations.
Key Benefits- Enhanced Repeatability: Maintains a high degree of accuracy within ±2% to ensure precise pressure monitoring.
- Versatile Mounting: The Series 1800 design allows for mounting on one side of a panel with adjustment access on the other.
- High Electrical Capacity: Features 15A electrical ratings at up to 480 VAC, suitable for direct control of small motors and fans.
- Compact Profile: Small footprint ideal for space-constrained mechanical rooms and control cabinets.
- Reliable Deadband: Optimized with an approximate deadband of 0.35" to 0.70" w.c. for stable switching cycles.
What is the maximum pressure this switch can handle?
The Dwyer 1823-20 has a continuous pressure limit of 10 psig and can withstand surges up to 25 psig, making it suitable for standard low pressure differential applications.
How do you adjust the set point on the 1823-20?
Adjustment is performed by turning the slotted screw inside the mounting spud—clockwise to increase the set point and counterclockwise to decrease it. Ensure the diaphragm is in a vertical position during calibration.
Is this switch compatible with combustible media?
No, this unit is strictly for use with air and non-combustible, compatible gases. Using it with hazardous or combustible fluids could compromise the system and safety.
