Product Details
Dwyer 2000 Series Magnehelic Differential Pressure Gauge
Product Introduction
The Dwyer 2000 Series Magnehelic differential pressure gauge
combines precision, durability, and versatility to meet diverse
industrial and scientific needs. With an accuracy of ±2% of full
scale and 81 selectable ranges, it precisely measures low positive,
negative (vacuum), or differential pressures of air and
non-combustible gases. Its patented, wear-free Magnehelic moving
parts enable rapid response to pressure changes, while shockproof
and overpressure-resistant design ensures reliable operation. Ideal
for applications ranging from HVAC systems and industrial process
control to medical equipment, this gauge eliminates issues like
liquid evaporation or freezing, making it a cost-effective and
low-maintenance solution.
Key Features
- High Precision: ±2% full-scale accuracy (FS) for reliable and
consistent readings across 81 range options.
- Rapid Response: Patented Magnehelic technology provides instant
pressure change detection, minimizing assessment delays.
- Robust Construction: Stainless steel housing with IP67 enclosure
rating resists dust, water, shock, and overpressure (relief plug
activates at 25 psig for standard models).
- Longevity & Low Maintenance: Durable components ensure extended
service life and reduced downtime.
- User-Friendly Design: Large 1000mm digital display with an
undistorted plastic face for easy viewing from a distance.
- Versatile Output: 4-20mA electrical output enables seamless
integration with control systems.
