Dwyer Instruments 2304 Pressure Gage
The Dwyer Instruments 2304 Magnehelic Pressure Gage is a staple for HVAC contractors requiring precise monitoring of low differential pressure in air and non-combustible gases. Featuring a 2-0-2" w.c. zero center range, this gage is specifically engineered to indicate both positive and negative pressures relative to a set point, making it ideal for clean room positive pressure monitoring or building pressurization balancing. The unit utilizes a frictionless Magnehelic movement with a silicone rubber diaphragm, ensuring a 2% accuracy rating without the maintenance or leveling issues associated with traditional liquid manometers. Industry professionals rely on this differential pressure gage for its durable die-cast aluminum case and IP67-rated weatherproof construction. With standard 1/8" female NPT process connections located on both the side and back, the 2304 offers flexible installation for filter monitoring or fan pressure indication. Whether you are performing a flush mount in a control panel or a surface mount on a duct, the high-visibility 4-inch dial provides clear, undistorted readings for critical airflow diagnostics.
Key Benefits
- Bi-Directional Sensing: The 2-0-2" w.c. scale allows for immediate detection of pressure shifts in either direction from zero.
- Rugged Reliability: Designed to withstand shock, vibration, and overpressure up to 15 psig through a integrated rubber relief plug.
- Maintenance-Free Design: Frictionless movement eliminates the need for lubrication or external power, reducing long-term service calls.
- Versatile Mounting: Includes hardware for both flange and flush mount configurations, adapting to different mechanical room layouts.
- Environmental Protection: The baked gray enamel finish and IP67-rated enclosure resist corrosion in demanding commercial environments.
Common Questions
Can the Dwyer 2304 be used in any orientation?
For maximum accuracy, this low pressure gage should be calibrated and mounted with the diaphragm in the vertical position. If horizontal mounting is required, the gage must be re-zeroed, though accuracy may be slightly affected on ultra-low ranges.
Is this gage compatible with natural gas?
The standard 2304 is designed for air and compatible non-combustible gases. For natural gas applications, a specific variant with a Buna-N diaphragm and different pressure ratings is required to ensure chemical compatibility.
How do I zero the gage after installation?
With both the high and low-pressure ports vented to the atmosphere, use the external zero adjustment screw located at the bottom of the transparent cover to align the pointer precisely with the zero mark.
