Product Description

Dwyer 2000 Series 0–3 kPa Magnehelic Differential Pressure Gauge 

The Dwyer 2000 Series 0–3 kPa Magnehelic Differential Pressure Gauge is a trusted solution for precise low-pressure measurement in HVAC, industrial, and cleanroom environments. Engineered with Dwyer's patented Magnehelic technology, this mechanical gauge combines magnetic sensitivity with a robust diaphragm design to deliver accurate differential pressure readings without requiring external power. Its 0–3 kPa (0–12" W.C.) measurement range and ±2% full-scale accuracy make it ideal for monitoring air filters, ventilation systems, cleanroom pressure differentials, and industrial dust collection systems where reliability and ease of use are critical.

The Magnehelic 2000 Series operates on a solenoid-driven magnetic helic mechanism, eliminating the need for electrical components and ensuring uninterrupted performance in demanding settings. The gauge's high-visibility dial with a red/black pointer provides clear, at-a-glance readings, while its 1/4" NPT female or hose barb process connections allow seamless integration with ducts, pipelines, and HVAC systems. Designed for durability, the gauge features aluminum alloy housing, Buna-N diaphragm, and brass wetted parts, offering resistance to corrosion and mechanical stress. Its IP65/NEMA 4X-rated enclosure ensures protection against dust, water, and environmental contaminants, even in harsh industrial conditions.

Certified to meet CE, RoHS, CSA, and UL standards, the Dwyer 2000 Series is approved for use in HVAC compliance, pharmaceutical cleanrooms, laboratory fume hoods, and food processing facilities. The gauge operates reliably across a -40°C to +65°C (-40°F to 150°F) temperature range and withstands overpressure up to 10× full scale (30 kPa) without damage, ensuring long-term stability in dynamic environments. Its adjustable set points (available with optional switches) enable customizable alarm thresholds for filter clogging, system efficiency monitoring, or airflow control.

Key advantages include zero calibration requirements, low-maintenance operation, and rapid response time (<2 seconds) for real-time pressure tracking.
