Dwyer Series 2000 Magnehelic Differential Pressure Gage (Model 2300-60PA)

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).
