Dwyer Series 3000 Precision Magnehelic Differential Pressure Gauge
-68~103Kpa, Stainless Steel Body
Product Introduction
The Series 3000 Precision Magnehelic Gauge is an advanced
differential pressure measurement instrument designed for critical
applications requiring high accuracy and reliability. Engineered
with dual stainless steel bellows sensors, it precisely measures
pressure differentials across filters, air ducts, and industrial
systems. The gauge features a large, easy-to-read analog dial with
a corrosion-resistant aluminum housing, making it ideal for harsh
environments. Equipped with 1/8" NPT ports and compatible with
various media, it offers flexible installation options for HVAC,
cleanrooms, and process control systems.
Key Features
Ultra-Precision Measurement
±1% full-scale accuracy (-HA model) ensures precise readings in
critical applications, twice as accurate as standard gauges.
Robust Construction
Die-cast aluminum housing with gray epoxy coating withstands
168-hour salt spray testing, ensuring durability in corrosive
environments.
Enhanced Visibility
Large 4" diameter anti-distortion acrylic dial allows clear
readings from distances up to 10 meters.
Quick Response
Patented Magnehelic design provides instantaneous response to
pressure changes, enabling real-time system monitoring.
Wide Operating Range
Measures from -68 to 103Kpa with a maximum working pressure of 15
PSI (1.03 bar), expandable to 80 PSI (5.52 bar) with HP option.
IP67 Protection
Sealed enclosure prevents dust ingress and water immersion,
suitable for outdoor and wet environments.
Versatile Mounting
Includes flush-mount adapters and dual pressure ports (side and
back) for flexible installation in any orientation.
Safety Relief
Built-in overpressure relief plug activates at 25 PSI (1.72 bar),
protecting the gauge from damage.
