Dwyer� Magnehelic Differential Pressure Gauge

Portable magnehelic gage from Dwyer Instruments measures differential air pressure

 

Measure differential air pressure with this simple, accurate, portable magnehelic gage
 

Easy and accurate.  The Dwyer� Magnehelic Differential Pressure Gauge offers accurate differential pressure readings to �2% over the full scale.  Units with the Air Velocity Scale provide direct readings for standard air without conversions.  This portable gauge is handy to use

on a ladder or in confined locations encountered in the field. Dwyer magnetic linkage provides exceptionally responsive, consistently accurate indication of air velocity, positive, negative or differential pressures in air and non-corrosive gases. Pointer movement is inertia-free and drift-free. Highly resistant to shock and vibration. Use the pitot tube (included) for air velocity measurement-- or without for pressure measurement.

   Features:

   � Over 80 models and measurement ranges to choose from.  

   � Set screw enables accurate zeroing.  

   � Ambient operating temperature range 30 to 140�F. 

   � Aluminum stand iridite-dipped; gauge has baked gray hammerloid finish. 

   � Connections: 1/8" NPT. high and low press. taps, one pair side and one pair back.  Two 1/8" NPT plugs included. 

   � Includes one 9 ft. length of 3/16" I.D. tubing, rigid insertion tube, and two pipe thread to tubing adapters. 

   � Furnished in hard plastic, padded carrying case. 

   � Minor assembly required.

     Pitot tubes are ideal for use with our precision manometers and air velocity gauges, Dwyer� Pitot Tubes are constructed from corrosion resistant stainless steel for a lifetime of service. ASME design meets AMCA and ASHRAE specifications for maximum accuracy over a wide variety of flow conditions. No correction factors required as ASHRAE tip design yields a calibration factor of 1. ASHRAE design needs no calibration! 

     Permanent, stamped insertion depth graduations on sides of 160 series facilitate accurate positioning. Static pressure port is parallel to sensing tube allowing quick, easy alignment of tube with air flow. Low sensitivity to misalignment gives accurate reading even when tube is misaligned up to 15 degrees. Various standard sizes are available for use in ducts as small as 4" dia. or as large as 36 ft. dia.
Pitot Tube Features
� No calibration needed.
� Precisely located, burr-free static pressure holes.
� Hemispherical tip design, best for accuracy if imperfectly aligned and nearly impossible to damage.
� Long lasting 304 stainless steel construction.
� Silver soldered connections for leak-proof operation.
� ASME design meets AMCA and ASHRAE specification.
� Coefficient of "1."
� 5/16" models rated to 1500�F.
� Extended static connection helps guide tip within recommended 15� of air flow direction.
� Inch graduations on sides of 160 series to quickly determine exact insertion depth.
� Dwyer� Air Velocity Calculator, direct reading flow charts and instructions included.
� Use 1/8" models in ducts as small as 4", 5/16" models in ducts 10" or larger.
� Optional mounting gland or split flange make permanent installation fast and simple.
