Dwyer Instruments 1910-1 Pressure Switch

Dwyer Instruments 1910-1 Pressure Switch

The Dwyer 1910-1 is a precision-engineered low differential pressure switch designed for monitoring air and non-combustible gases in demanding HVAC and industrial automation environments. This series 1900 set-point controller features an adjustable range of 0.40" to 1.6" w.c., making it ideal for clogged filter detection and fan proving applications. The unit utilizes a Single Pole Double Throw (SPDT) switch, allowing for versatile wiring configurations in normally open or normally closed circuits. With an approximate deadband of 0.15" to 0.16" w.c. and a continuous pressure limit of 45" w.c., the Dwyer 1910-1 ensures reliable performance without frequent cycling in high-velocity duct systems. The diaphragm-operated design provides high sensitivity and repeat accuracy at low pressures, while the compact explosion-proof capable housing (when used with appropriate enclosures) withstands standard mechanical room vibrations. For contractors prioritizing system uptime, the 1910-1 offers a rugged, field-adjustable solution for air pressure sensing and draft control.

Key Benefits for Technicians
  • Field Adjustable Range: Set point is easily tuned between 0.40" and 1.6" w.c. using the internal adjustment screw for precise HVAC pressure monitoring.
  • Industrial Build Quality: Features a silicone diaphragm and painted steel housing to endure continuous operation in air handling units.
  • High Pressure Tolerance: Rated for a 45" w.c. continuous pressure limit, preventing damage during system surges or static pressure spikes.
  • Versatile Compatibility: Functions seamlessly with air and compatible non-combustible gases in positive, negative, or differential pressure applications.
Common Questions

What is the maximum temperature rating for the Dwyer 1910-1?
This switch is designed to operate in ambient temperatures ranging from -30 to 180°F (-34 to 82.2°C), ensuring stability in unconditioned mechanical spaces.

Can the 1910-1 be used for liquid flow monitoring?
No, this model is strictly for use with air and non-combustible gases. For liquid applications, a different series designed for compatible fluids must be used.

How do I connect the pressure lines?
The unit features 1/8" female NPT connections. Use professional-grade pipe thread sealant and ensure connections are tight to prevent leakage in differential pressure switch circuits.
