Product Parameter

General Specifications

• 17 to 36 VDC or isolated 21.6 to 33 VAC (3-wire)
• Weight: 8.0 oz (230 g)

Magnesense must be installed on a plane that is perpendicular to the horizontal plane. The pressure connection hole and wire connection pipe must be oriented downward. Fix it stably on the plane with three screws, not too tight. If you choose other installation Angle, will cause a large loss of accuracy.

• Adjustable Digital Dampening smooths out unstable pressure fluctuations common in air flow applications.

• Field Selectable Air Velocity Mode for fan and blower applications. Unit provides square root output that accurately tracks fpm or m/s flow rate. No need for a smart programmable indicator or PLC to convert pressure to air flow. Reduces components and installation time lowering overall costs.
