Dwyer Series 2000 Magnehelic Differential Pressure Gauge with ±2% FS Accuracy and Frictionless Magnetic Movement for 20-140°F Applications

The Dwyer Series 2000 Magnehelic Differential Pressure Gauge (0-60 Pa) is a high-accuracy instrument designed for precise measurement of low-pressure air and non-corrosive gas systems. Engineered with Dwyer's frictionless magnetic movement, it delivers reliable readings within ±2% of full scale, making it ideal for applications requiring sensitive pressure monitoring.

The gauge quickly indicates positive, negative (vacuum), or differential pressures, while its rugged design resists shock, vibration, and overpressure. Free from manometer fluid issues like evaporation or freezing, this cost-effective solution is the industry standard for filter monitoring, clean room pressure control, air velocity measurement, and more.

• Precision Measurement: 0-60 Pa range with ±2% full-scale accuracy at 70°F (21.1°C), ensuring reliable low-pressure readings. Minor divisions of 2.0 Pa for detailed pressure resolution.
• Frictionless Magnetic Technology: Dwyer's Magnehelic movement eliminates mechanical wear, providing consistent performance over time.
• Versatile Pressure Types: Measures positive, negative (vacuum), or differential pressures in air and non-corrosive gases. Optional Buna-N diaphragm for hydrogen applications (pressures <35 psi).
• Robust Construction: Die-cast aluminum housing with gray corrosion-resistant coating (passes 168-hour salt spray test). Overpressure relief plug activates at ~25 psig (1.72 bar) for standard models.
• Low-Maintenance Design: No manometer fluid required, eliminating evaporation, freezing, or toxicity concerns.
• Industrial Compliance: Suitable for ATEX-approved applications (refer to Series AT22000 for certified models).
• Wide Application Range: Filter monitoring, clean room positive pressure, air velocity (with Pitot tube), blower vacuum, and HVAC systems.
