MAGNEHELIC 進口差壓表 2300-60PA
Series 2000 Magnehelic® Gage
for a versatile low differential pressure gage with a wide choice of 81 models and 27 options to choose from. Using Dwyer’s simple, frictionless Magnehelic® gage movement, it quickly indicates air or noncorrosive gas pressures--either positive, negative (vacuum) or differential. The design resists shock, vibration, over-pressures and is weatherproof to IP67. Select the
Also included with the –HA option at no extra cost are a mirrored scale overlay and a 6 point calibration certificate.

Mounting and Orientation
A single case size is used for most models of Magnehelic® gages. They can be flush or surface mounted with standard hardware supplied. Standard gages are calibrated in the vertical position, and should be used in that position for maximum stated accuracy. Ranges above 17.5 in w.c. may be used at any angle, and should stay within specified accuracy, by simply re-zeroing. Ranges below 17.5 in w.c. should be ordered using the –TA tilt angle option with the angle specified. These characteristics make Magnehelic® gages ideal for both stationary and portable applications. A 4-9/16" hole is required for flush panel mounting. Complete mounting and connection fittings, plus instructions, are furnished with each instrument.
