Dwyer Series 2000 Magnehelic Differential Pressure Gage (Model
2300-60PA)
Product Introduction
The Dwyer Series 2000 Magnehelic Differential Pressure Gage (Model
2300-60PA) is a versatile, low-cost solution for measuring
positive, negative, or differential pressures in air and
non-corrosive gas systems. With a range of 30-0-30 Pa and 1.0 Pa
minor divisions, it offers precise readings for critical
applications like filter monitoring, clean room pressurization, and
HVAC systems. Calibrated for vertical mounting, this gage utilizes
Dwyer’s frictionless magnetic movement to ensure reliable
performance without power requirements, making it ideal for
isolation environments, hospitals, and temporary setups. Its rugged
design resists shock, vibration, and overpressure, with an IP67
enclosure rating for weatherproofing. The optional -HA
high-accuracy model achieves ±1% full-scale accuracy, complemented
by a mirrored scale and calibration certificate.
Key Features
Precision Measurement:
Range: 30-0-30 Pa with 1.0 Pa minor divisions, calibrated for
vertical scale position.
Accuracy: ±2% of full scale (±1% with -HA high-accuracy option) at
70°F (21.1°C).
Measures positive, negative (vacuum), or differential pressures in
air and non-corrosive gases.
Durable & Rugged Design:
Die-cast aluminum case with iridite dip and baked gray finish,
passing 168-hour salt spray tests.
IP67 enclosure rating for weatherproofing and protection against
dust/water immersion.
Overpressure relief plug opens at ~25 psig (1.72 bar) to prevent
damage (standard models).
Functional Versatility:
No power required, suitable for isolation/hospital environments and
temporary units.
1/8" female NPT pressure taps (side and back) for flexible
installation.
Applications include filter monitoring, air velocity with Pitot
tubes, blower vacuum, and room pressure indication.
User-Friendly Design:
4" diameter dial with clear acrylic cover for undistorted,
far-viewing readability.
Red-tipped aluminum pointer on a precision litho-printed scale.
Zero adjustment screw accessible without removing the cover; O-ring
sealed for pressure tightness.
Technical Specifications:
Pressure limits: -20 in Hg to 15 psig (-0.677 to 1.034 bar);
optional MP/HP up to 35/80 psig.
Temperature range: 20-140°F (-6.67-60°C); -20°F (-28°C) with
low-temperature option.
Weight: 1 lb 2 oz (510 g); includes mounting adapters and plugs.
Safety & Compliance:
Meets EU RoHS II Directive (2011/65/EU); explosion-proof options
via Series AT-2000 for ATEX zones.
Compatible with hydrogen when ordered with Buna-N diaphragm
(pressures <35 psi).
