Minihelic® II Differential
Pressure Gages
|
|
Combining
High Accuracy, Compactness, Dependability, and Low Cost
|
|
Combining
clean design,
small size and low cost with enough accuracy for all but
|
|
the most
demanding applications our Minihelic®
II gage offers the latest in design
|
|
features for a dial type differential pressure gage. It is our
most compact gage but
|
|
is easy to read and can safely operate at total pressures up to 30
psig. The Minihelic® II
|
|
is designed for panel mounting in a single 2-5/8” diameter hole.
Standard pressure
|
|
connections
are barbed fittings for 3/16” I.D. tubing; optional 1/8” male NPT
connections
|
|
are also available. Over-pressure protection is built into
the Minihelic® II gage by means of a
|
|
blow-out membrane molded in conjunction with the diaphragm.
Accidental over-ranging up to
|
|
the rated total pressure will not damage the gage. With
removable lens and rear housing, the
|
|
gage may be easily serviced at minimum cost.
|
|
|
|
With the housing molded from mineral and glass filled nylon and
the lens molded from acrylic,
|
|
the gage will withstand rough use and exposure as
well as high total pressure. The 5% accuracy
|
|
and low cost of the Minihelic®
II gage make it well-suited for a wide variety of OEM and user
|
|
applications. OEM applications
include cabinet air purging, medical respiratory therapy equipment,
|
|
air samplers, laminar flow hoods, and electronic
air cooling systems. As an air filter gage, the
|
|
Minihelic® II gage finds many
end use applications on large stationary engines, compressors,
|
|
ventilators, and air handling
units. The Minihelic® II gage is
suitable for many of the same
|
|
applications as the Magnehelic®
gage where the greater accuracy, sensitivity, and higher and
|
|
lower differential pressure ranges of the Magnehelic® gage are not required.
