Dwyer Dwyer-2020 Magnehelic differential pressure gauge 0-20 inches W.C. (4 inches dial) 2020

Product Description

Dwyer DWYER-2020 Magnehelic differential pressure gauge measures air and compatible noncorrosive gas pressures across a 0-20 in. W.C. range. The instrument indicates positive, negative and differential pressure with a frictionless magnet-driven helix and a silicone rubber diaphragm. It provides a 4 in. precision litho-printed dial, panel-mount bezel, IP67 enclosure rating, and overpressure relief for common HVAC, filter monitoring, duct pressure, blower and cleanroom applications.

• 0-20 in. W.C. measurement range with 4 in. dial, precision litho-printed scale and red-tipped pointer
• Die-cast aluminum case with acrylic/plastic cover, IP67 enclosure rating and blowout relief plug for overpressure protection
• Samarium cobalt magnet-driven helix, jeweled bearings with silicone fluid damping, silicone rubber diaphragm and zero adjustment; 1/8 in. female NPT process connections

Product Highlights

Differential pressure gauge for air and noncombustible gases; 0-20 in. W.C. range, 4 in. dial, IP67 enclosure, optional -HA high accuracy (1% FS).
