Series 2000 Magnehelic Differential Pressure Gages

Series 2000 Magnehelic Differential Pressure Gages

Product Introduction

The Series 2000 Magnehelic Differential Pressure Gages are versatile, mechanical instruments designed for precise low-pressure measurement in air and noncorrosive gas systems. With 81 models and 27 options, they indicate positive, negative (vacuum), or differential pressure without requiring power—making them ideal for isolation/hospital environments, temporary setups, and applications where electrical connectivity is limited. Leveraging Dwyer’s frictionless Magnehelic® movement, these gages offer accuracy within 1% of full scale (with the -HA High Accuracy option), resisting shock, vibration, over-pressures, and featuring an IP67 weatherproof rating. A mirrored scale overlay and 6-point calibration certificate are included with the -HA option at no extra cost.

Product Features

Mechanical Operation:

No power required for operation, suitable for off-grid or temporary installations.

Direct mechanical indication of pressure via frictionless Magnehelic® movement.

Accuracy & Range:

Standard accuracy: ±2% FS; -HA option achieves ±1% FS for critical measurements.

Wide pressure range options (e.g., 0–0.1" w.c. to 0–250" w.c.) across 81 models.

Environmental Resistance:

IP67 weatherproof rating; resists dust, water, shock, and vibration.

Over-pressure tolerance: Suitable for pressures <35 psi (with Buna-N diaphragm for hydrogen applications).

Calibration & Certification:

-HA models include mirrored scale overlay to reduce parallax error.

NIST calibration and 6-point certification available via Product Configurator.

Versatile Applications:

Hospital isolation wards, clean rooms, and temporary medical units.

HVAC duct pressure monitoring, filter status indication, and building pressurization.

Cost-Effective Design:

Low-cost alternative to electronic gauges without compromising reliability.

Simple installation and maintenance-free operation.
