Dwyer Instruments 1910-00 Pressure Switch
The Dwyer Instruments 1910-0 Pressure Switch is a professional-grade differential pressure switch engineered for precision monitoring of air and non-combustible gases in HVACR systems. This SPDT switch operates within a precise range of 0.07" w.c. to 0.15" w.c., making it an essential component for clogged filter detection, fan proving, and ventilation flow monitoring. With a 0.04" approximate deadband and a 45" w.c. continuous pressure limit, this unit ensures reliable performance without frequent cycling in low-pressure applications. The silicone diaphragm and die-cast aluminum housing provide the durability required for industrial environments, including refrigeration and oven air service. Installation is streamlined via dual 1/8" female NPT connections, and the internal set point adjustment screw is protected within the conduit enclosure to prevent unauthorized tampering, a critical feature for building automation systems and VAV controller deployments.
Key Benefits- High Sensitivity: Optimized for ultra-low pressure ranges (0.07 to 0.15" w.c.) to detect subtle flow changes.
- Tamper-Resistant Design: Set point adjustment is located inside the conduit enclosure for added security.
- Versatile Electrical Rating: Features SPDT contacts rated for up to 15A at 120-480 VAC for direct equipment control.
- Rugged Construction: Durable metallic housing with a temperature range of -30°F to 180°F for demanding mechanical rooms.
- Broad Compatibility: Suitable for use with air and inert gases in variable air volume systems and refrigeration coils.
What is the proper mounting orientation for the Dwyer 1910-0?
This switch must be mounted with the diaphragm in a vertical position to ensure accuracy. Mounting it horizontally can shift the set point due to the weight of the internal components.
Can this pressure switch be used for manual reset applications?
The model 1910-00 is an automatic reset switch. If your application requires a manual reset for safety interlocking, a specific MR suffix model would be required.
What type of tubing is recommended for the 1/8" NPT ports?
Standard metal or plastic tubing with compatible fittings can be used. For high-cycle or high-vibration environments, ensure the tubing is secured to avoid false pressure readings at the diaphragm.
