Dwyer Instruments 1910-10 Pressure Switch
The Dwyer Instruments 1910-10 is a field-proven low differential pressure switch engineered for high-precision monitoring of air and non-combustible gases in demanding HVAC applications. This compact Series 1900 component features a versatile SPDT switch, providing reliable control or alarm signaling for systems requiring set points between 3.0" w.c. and 11.75" w.c. Built for the job site, the 1910-10 utilizes a clear-to-access internal set point adjustment screw protected within a conduit enclosure to prevent unauthorized tampering while simplifying calibration during routine maintenance. Designed specifically for differential pressure monitoring, this unit maintains a consistent 0.40" w.c. deadband and an impressive repeatability of ±3%, ensuring your building automation system (BAS) receives accurate data for secondary control. Its rugged, zinc-plated steel housing and high-quality silicone diaphragm enable the switch to handle a 45" w.c. continuous pressure limit and surges up to 10 psig. With standard 1/8" female NPT pressure ports and a 15A electrical rating at 120-480 VAC, the Dwyer 1910-10 is the industry standard for clogged filter detection, coil icing protection, and VAV controller applications.
Key Benefits- Broad Operating Range: Adjustable set points from 3.0" to 11.75" w.c. accommodate high-static duct environments and industrial dryer applications.
- Contractor-Grade Reliability: Features a high-capacity SPDT snap switch rated for 15A, supporting direct integration with motors and contactors.
- Tamper-Resistant Design: The internal range screw ensures that critical safety and performance set points remain exactly where you calibrate them.
- Flexible Installation: Compact footprint with a 3.5-inch diameter allows for mounting in tight mechanical rooms and OEM enclosures.
- Exceptional Durability: Withstands temperatures from -30°F to 180°F, making it suitable for unconditioned rooftop units and refrigeration service.
How do you adjust the set point on a Dwyer 1910-10?
To adjust the 1910-10, remove the conduit enclosure cover. Use a screwdriver to turn the internal adjustment screw; turning it clockwise increases the set point. For precise calibration, always use a calibrated manometer to verify the switch-actuation point.
Can this pressure switch be mounted in any orientation?
For maximum accuracy and to meet factory specifications, the Dwyer 1910-10 should be mounted with the diaphragm in a vertical position. Mounting in other orientations can shift the set point due to the effect of gravity on the internal diaphragm assembly.
What happens if the pressure exceeds the 45" w.c. limit?
While the 1910-10 has a surge limit of 10 psig, exceeding the 45" w.c. continuous operating limit can lead to set point drift or diaphragm fatigue. For high-pressure applications, ensure the static pressure remains within the specified proof pressure to maintain long-term repeatability.
