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.

• 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.
