Dwyer Instruments 15PSIG Magnehelic Gauge 2002C AV

The Dwyer Instruments 15PSIG Magnehelic Gauge 2002C AV is a precision differential pressure gauge designed to measure low air or non-combustible gas pressures. It offers accurate readings for positive, negative, or differential pressures, making it suitable for various industrial applications.

Key Features

• Measurement Range: 0 to 2 inches of water column (in. w.c.), with a corresponding velocity range of 1,000 to 5,600 feet per minute (FPM).
• Accuracy: ±2% of full scale, ensuring reliable and precise measurements.
• Pressure Limits: Capable of withstanding pressures from -20 inches of mercury (inHg) to 15 pounds per square inch gauge (psig).
• Temperature Range: Operates effectively between 20°F (-6.67°C) and 140°F (60°C).
• Construction: Features a durable die-cast aluminum case with an acrylic cover, providing resistance to corrosion and ensuring longevity.
• Enclosure Rating: Rated IP67, offering protection against dust and water ingress.
• Mounting Options: Equipped with a bezel for flush panel mounting, facilitating easy installation.
• Process Connections: Includes 1/8-inch female NPT duplicate high and low pressure taps, with one pair on the side and one pair on the back, allowing flexible connection options.

Applications

The 2002C AV Magnehelic Gauge is ideal for monitoring fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drops across orifice plates, liquid levels in bubbler systems, and pressures in fluidic systems. Its robust design and high accuracy make it a reliable choice for critical pressure measurement tasks.

Additional Information

The gauge’s motion is damped with high-viscosity silicone fluid, ensuring smooth pointer movement. A zero adjustment screw is conveniently located in the plastic cover, accessible without removing the cover, allowing for easy calibration. The rugged design resists shock, vibration, and overpressure, contributing to a long service life and minimized downtime.

For enhanced safety, the gauge includes a relief plug that opens at approximately 25 psig (1.72 bar) to prevent overpressure damage. The device is compliant with RoHS II standards, meeting the technical requirements of EU Directive 2011/65/EU.

In summary, the Dwyer Instruments 15PSIG Magnehelic Gauge 2002C AV combines precision, durability, and versatility, making it an essential tool for accurate differential pressure measurement in various industrial settings.
