Dwyer Magnehelic 2300-60PA Differential Pressure Gage
Product Introduction
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. Ideal for industrial applications like filter monitoring, HVAC systems, and clean room pressurization, the gage resists shock, vibration, and overpressure, ensuring durability in harsh environments. Its compact design allows flush or surface mounting, and the optional -HA model enhances accuracy to ±1% for critical measurements.
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).
Technical Specs:
Pressure limits: -20 in Hg to 15 psig (-0.677 to 1.034 bar); MP/HP options up to 35/80 psig.
Temperature range: 20-140°F (-6.67-60°C); -20°F (-28°C) with low-temp option.
Weight: 1 lb 2 oz (510 g); includes mounting adapters and plugs.
Safety & Compliance:
Meets RoHS II standards (excluding -SP models).
Explosion-proof variants available via Series AT-2000 for ATEX zones.
