500 psi max 10 psi dif pressure guage dwyer capsuhelic
I each used pressure guage for single source or to messure differential pressure from two sources. 0 - 10 PSI. Max operating pressure 500 PSI.
Ambient temperature range: 20? to 140?F.* (-7? to 140?C) 1/8"' NPT female high and low pressure taps duplicated - one pair side and one pair back. Housing: Die cast aluminum. Case and aluminum parts Iridite-dipped to withstand 168 hour salt spray test. Exterior finish is baked dark gray hammerloid. Accuracy: Plus or minus 2% of full scale, throughout range at 70?F.
Select the Dwyer Magnehelic gage for high accuracy - guaranteed within 2% of full scale - to suit your needs precisely. Using Dwyer's simple, frictionless
Magnehelic movement, it quickly indicates low air or non-corrosive gas pressures-either positive,
negative (vacuum) or differential. The design resists shock, vibration and over-pressures. No manometer
fluid to evaporate, freeze or cause toxic or leveling problems. It's inexpensive, too.
Widely used 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. It also checks gas-air ratio controls and automatic valves, and monitors blood and respiratory
pressures in medical care equipment.
A single case size is used for most ranges of Magnehelic gages. They can be flush or surface mounted
with standard hardware supplied. With the optional A-610 Pipe Mounting Kit they may be conveniently
installed on horizontal or vertical 1¼" - 2" pipe. Although calibrated for vertical position, many ranges
above 1 inch may be used at any angle by simply re-zeroing. However, for maximum accuracy, they
must be calibrated in the same position in which they are used. 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
Ambient temperature range: 20° to 140°F.* (-7° to 140°C)
Connections: 1/8"' NPT female high and low pressure taps duplicated - one pair side and one pair back.
Housing: Bronz. Case and aluminum parts Iridite-dipped to withstand 168 hour salt spray
test. Exterior finish is baked dark gray hammerloid.
Accuracy: Plus or minus 2% of full scale (3% on - 0 and 4% on - 00 ranges), throughout range at 70°F.
Quality design and construction features
Bezel provides flange for flush mounting in panel.
Clear plastic face is highly resistant to breakage. Provides undistorted viewing of pointer and scale.
Precision litho-printed scale is accurate and easy to read.
Red tipped pointer of heat treated aluminum tubing is easy to see. It is rigidly mounted on helix shaft.
Pointer stops of molded rubber prevent pointer over-travel without damage.
"Wishbone" assembly provides mounting for helix, helix bearings and pointer shaft.
Jeweled bearings are shock-resistant mounted; provide virtually friction-free motion for helix. Motion
damped with high viscosity silicone fluid.
Zero adjustment screw is conveniently located in plastic cover, accessible without removing cover. Oring
seal provides pressure tightness.
Helix is precision milled from an alloy of high magnetic permeability. Mounted in jeweled bearings, it
turns freely to align with magnetic field of magnet to transmit pressure indication.
Samarium Cobalt magnet mounted at one end of range spring rotates helix without mechanical
Calibrated range spring is flat spring steel in temperature compensated design. Small amplitude of
motion assures consistency and long life. It reacts to pressure on diaphragm. Live length adjustable for
Silicone rubber diaphragm with integrally molded O-ring is supported by front and rear plates. It is
locked and sealed in position with a sealing plate and retaining ring. Diaphragm motion is restricted to
prevent damage due to overpressures.
Die cast aluminum case is precision made. Iridite-dipped to withstand 168 hour salt spray test. Exterior
finished in baked dark gray hammerloid. One case size used for all standard pressure ranges, and for
both surface and flush mounting.
"O" ring seal for cover assures pressure integrity of case.
