Dwyer Instruments 2302 Pressure Gage
The Dwyer Instruments 2302 Magnehelic Differential Pressure Gage is a staple in the HVACR industry for monitoring low-pressure air or non-combustible gases. Featuring a 1-0-1" w.c. zero center range, this gage is specifically designed for applications requiring precise measurement of both positive and negative differential pressures. Built with a frictionless Magnehelic movement, it provides high sensitivity without the risk of fluid evaporation or freezing, ensuring reliable performance in harsh field conditions. The 4" diameter dial face offers clear visibility, while the 1/8" female NPT process connections allow for seamless integration into standard pneumatic lines. Whether you are performing flange or flush mounting in a control panel or a fan system, this gage delivers the accuracy needed for filter monitoring, duct static pressure measurement, and fan pressure detection. Its rugged die-cast aluminum housing is built to withstand mechanical vibration and overpressure, making it a dependable choice for technical balancing and system diagnostics.
Key Benefits- Zero-center configuration allows for immediate detection of pressure fluctuations across a neutral point.
- Magnehelic magnetic linkage eliminates mechanical friction, reducing maintenance and preventing needle sticking.
- Universal mounting versatility supports both surface and flush-mounting for cabinet or wall installations.
- High overpressure protection is provided by a blow-out plug and diaphragm design to prevent damage during surges.
- Resistance to environmental factors ensures accuracy in a variety of temperatures and humidity levels.
Can the Dwyer 2302 be used with liquid media?
No, this gage is strictly designed for use with air and non-combustible gases. Using liquids will damage the internal diaphragm and 1/8" NPT ports.
What is the accuracy rating for this specific Magnehelic gage?
This differential pressure gage typically maintains an accuracy of +/- 2% of the full scale throughout its range, provided it is calibrated and mounted in the vertical position.
Is the zero-point adjustable if the needle shifts?
Yes, there is an external zero-adjust screw located on the bottom of the cover, allowing for easy recalibration without disassembly.
