Series 2000 Magnehelic® Differential Pressure Gage
Indicate Positive, Negative, or Differential Pressure
DESCRIPTION
Select the Magnehelic® gage for high accuracy - guaranteed within 2% of full scale and for the wide choice of ranges available to suit your needs precisely. Using the 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.

SPECIFICATIONS
Ambient temperature range: 20° to 140°F* (-7° to 60°C).
Rated total pressure: -20" Hg. to 15 psig† (-68 kPa to 103 kPa).
Overpressure: Relief plug opens at approximately 25 psig (172 kPa).
Connections:1/8" NPT(F) 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 dark gray.
Accuracy: Plus or minus 2% of full scale (3% on -0 and 4% on -00
ranges), throughout range at 70ºF (21°C).
Standard accessories: Two 1/8 " NPT plugs for duplicate pressure
taps, two 1/8" pipe thread to rubber tubing adapters and
three flush mounting adapters with screws. (Mounting
ring and snap ring retainer substituted for 3 adapters in
MP & HP gage accessories.)
Weight: 1 Ib. 2 oz. (460 g)
Mounting: 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 11/4 " -2" pipe.
*Low temperature models available as special option.
†For applications with high cycle rate within gage total
pressure rating, next higher rating is recommended. See
Medium and High pressure options.
Although calibrated for vertical position, many ranges above 1"
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 instrument. Flush ...Surface...or Pipe Mounted.
