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˝ ID
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.
