Dwyer Instruments 2020 Pressure Gage
The Dwyer 2020 Magnehelic Gage is the industry standard for monitoring differential pressure in commercial HVAC systems, specifically designed for a range of 0-20.0" w.c.. This high-precision instrument utilizes a friction-free Magnehelic movement, ensuring rapid response to pressure changes without the maintenance requirements of liquid-filled manometers. Engineered for air and non-combustible gases, the 2020 model features a 4" diameter dial face for clear readability during system balancing or filter monitoring. The die-cast aluminum housing is rugged enough for mechanical rooms, supporting both flush mount and surface mounting configurations. With 1/8" female NPT process connections located at the back and side, this gage offers flexibility for various static pressure sensing setups. It remains a critical component for technicians requiring accurate low pressure measurement in air handling units, dust collectors, and cleanroom environments where precision and long-term stability are non-negotiable.
Key Benefits:
- Precision Accuracy: Guaranteed 2% accuracy across the full scale ensures reliable HVAC pressure monitoring.
- Frictionless Movement: The Magnehelic movement eliminates wear and hysteresis for consistent performance in the field.
- Versatile Mounting: Supports flange or flush installation to suit specific static pressure sensor requirements.
- Dual Ports: Provided back and side 1/8" NPT taps allow for simplified plumbing and integration.
- Durable Construction: Rated for pressures up to 15 psig, providing a high safety margin for standard air systems.
Common Questions:
What is the proper way to calibrate a Dwyer 2020 gage?
Technicians should vent both ports to the atmosphere and use the external zero adjustment screw located at the bottom of the faceplate to align the pointer with the zero mark.
Can the Dwyer 2020 be used with liquids?
No, this model is specifically engineered for air and non-combustible gases. Using liquids will damage the internal diaphragm and movement.
How do I handle high-vibration applications?
In high-vibration environments, utilize a snubbing orifice or remote mount the gage using flexible tubing to protect the sensitivity of the movement.
