Dwyer Instruments 2002 Pressure Gage
The Dwyer 2002 Magnehelic Gage is the industry standard for monitoring differential pressure in commercial HVAC systems, cleanrooms, and air handling units. Specifically calibrated for a range of 0-2.0" w.c., this diaphragm-actuated gage provides high-precision monitoring of air and compatible non-combustible gases with an accuracy of ±2% of full scale. The friction-free Magnehelic movement utilizes a high-torque magnetic linkage rather than mechanical gears, eliminating the risk of wear and backlash while providing superior resistance to shock and vibration. Designed for versatility in the field, the 4" diameter dial face features dual 1/8" female NPT taps on the back and sides, allowing for seamless integration into existing pneumatic lines via flange or flush mount configurations. Whether managing static pressure across filter banks or monitoring fan discharge, this gage ensures reliable mechanical indication without the need for external power, making it a staple for contractors requiring durable, long-term performance.
Key Benefits for Technicians- No Power Required: Mechanical operation ensures constant monitoring during power outages or in remote locations without wiring.
- High Overpressure Protection: Robust design includes a blowout plug to protect the internal diaphragm from surges up to 15 psig.
- Precise Calibration: The 0-2.0" w.c. range is ideal for low-pressure applications like filter monitoring and room pressure balancing.
- Durable Construction: Die-cast aluminum housing with a clear plastic face allows for clear visibility in harsh mechanical room environments.
How do I zero the Dwyer 2002 after installation?
Ensure both pressure ports are vented to the atmosphere. Use the external zero adjustment screw located at the bottom of the front cover to align the pointer with the zero mark.
Can I use this gage with water or hydraulic fluids?
No, the 2002 is designed strictly for air and non-combustible, compatible gases. Liquid media will damage the internal silicone diaphragm and magnetic movement.
What is the maximum temperature rating for this unit?
The standard Magnehelic gage is rated for ambient temperatures ranging from 20° to 140°F (-6.7° to 60°C). High-temperature models are required for applications exceeding these limits.
