Dwyer Magnehelic 2300-60PA Differential Pressure Gage
The Dwyer Magnehelic 2300-60PA is a high-accuracy differential pressure gage designed for measuring positive, negative, or differential pressures in air and non-corrosive gas systems. With a range of 60-0-60 Pa and ±2% full-scale accuracy, it leverages Dwyer's frictionless magnetic movement to deliver reliable readings without power requirements.
Key Features
Precision Measurement:
- Range: 60-0-60 Pa with minor divisions for detailed readings
- Accuracy: ±2% of full scale at 70°F (21.1°C); upgrade to -HA for ±1% accuracy
- Measures positive, negative (vacuum), or differential pressures in air/non-corrosive gases
Robust Construction:
- Die-cast aluminum case with gray finish, passing 168-hour salt spray tests
- IP67 enclosure rating for weatherproofing and protection against dust/water
- Overpressure relief plug activates at ~25 psig (1.72 bar) to prevent damage
Versatile Installation:
- 4" dial face with clear acrylic cover for undistorted viewing
- 1/8" female NPT taps (side/back) for flexible pressure connections
- Calibrated for vertical mounting; can be re-zeroed for other angles
Functional Flexibility:
- No power needed, suitable for isolation/hospital settings and temporary units
- Applications include filter resistance, air velocity (with Pitot tube), and blower pressure
- Compatible with hydrogen when ordered with Buna-N diaphragm (pressures <35 psi)
