Dwyer Series 2000 Magnehelic Differential Pressure Gauge (0–15 cm w.c.)

Product Introduction

Product Introduction

The Dwyer Series 2000 Magnehelic Differential Pressure Gauge (0–15 cm water column) is a precision analog instrument designed to measure pressure differences in low- to medium-pressure systems. Engineered with a rugged die-cast aluminum housing, it delivers ±2% full-scale accuracy for reliable monitoring of air and non-corrosive gas pressures. The gauge’s patented bellows sensing mechanism ensures quick response to pressure changes, while its clear dial and durable construction make it ideal for industrial applications such as filter monitoring, HVAC systems, and airflow management.

Product Features

Accurate Pressure Measurement:

0–15 cm w.c. range with ±2% full-scale accuracy at 70°F (21.1°C).

Clear analog dial with undistorted plastic face for easy reading from a distance.

Rugged Construction:

Die-cast aluminum case and bezel with acrylic cover, coated gray to withstand 168-hour salt spray tests.

IP67 enclosure rating for protection against dust and water immersion.

Quick Response Design:

Patented bellows sensing elements provide immediate reaction to pressure changes, eliminating assessment delays.

Versatile Installation:

1/8 NPT female process connections for easy integration into pipe systems.

Mounting orientation: diaphragm in vertical position (other orientations available on request).

Wide Operational Range:

Temperature tolerance: 20–140°F (-6.67–60°C); optional low-temperature model for -20°F (-28°C).

Pressure limits: -20 in Hg to 15 psig (-0.677 to 1.034 bar); MP/HP options for higher pressure ratings.

Low Maintenance:

Relief plug activates at ~25 psig (1.72 bar) to protect against overpressure.

Long service life with minimal downtime due to high-quality components.
