MORE ABOUT THIS ITEM

The Magnahelic guage is the industry standard to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels with bubbler systems, and pressures in fluid amplifier or fluidic systems. The gauge's motion is damped with high-viscosity silicone fluid. The zero adjustment screw is conveniently located in the plastic cover, and is accessible without removing the cover. O-ring seal provides pressure tightness. Rugged design resists shock, vibration, and overpressure.

The helix is precision-made from an alloy of high magnetic permeability. Mounted in jeweled bearings, it turns freely, following the maganetic field to move the pointer across the scale. The samarium cobalt magnet is mounted at one end of the range spring and rotates the helix without mechanical linkages.

FAQs of Dwyer USA Magnehelic Gauges 0 To 15 MM WC:

Q: How is the Dwyer Magnehelic Gauge 0 to 15 MM WC installed in a monitoring system?

A: Installation is straightforward since the gauge is designed for both surface and flush mounting. It comes with two self-tapping screws, two 1/8 NPT plugs, and two rubber tubing connectors. Process connections are available on both side and rear, making it versatile to fit various system layouts.

Q: What benefits does the immediate mechanical response provide in operation?

A: The immediate mechanical response means pressure changes are displayed in real time on the analog dial. This allows operators to quickly identify system performance issues or changes, helping to maintain optimal operating conditions and ensuring prompt corrective action if required.

Q: When should I use or select the 0 to 15 MM WC range for measuring differential pressure?

A: Select the 0 to 15 MM WC range when monitoring low differential air or gas pressures, such as in air handling units, filter status monitoring, and clean room environments where sensitive, accurate detection of pressure differences is critical for safety and efficiency.

Q: Where can I utilize this industrial grade Magnehelic pressure gauge?

A: This gauge is suitable for use in a variety of locations, such as commercial buildings, HVAC systems, laboratories, clean rooms, and process industries in India and abroad, wherever precise low pressure monitoring is required.

Q: What is the process for calibrating the gauge?

A: The gauge comes standardly calibrated at room temperature and in the vertical position. If recalibration is necessary, adjust the external zero adjustment knob to align the dial pointer to zero before use, ensuring highly accurate pressure readings.

Q: How does the overpressure protection enhance the gauges safety?

A: Overpressure protection allows the gauge to handle continuous pressures up to 15 psi (1.03 bar) without damage, providing peace of mind and longevity in situations where unexpected system surges may occur.

Q: What accessories are included with this Magnehelic gauge for easy setup?

A: The gauge package includes two self-tapping mounting screws, two 1/8 NPT plugs, and two rubber tubing connectors, ensuring you have everything needed for quick, secure installation and integration into your system.
