Product Description

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 gage 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.

  • Face Velocity on Fume Hood
  • Duct Pressures
  • Cabinet Air-Purging

Features

  • Housing is molded from strong mineral and glass filled nylon.
  • Pointer stops of molded rubber prevent pointer over-travel without
    damage.
  • Full view lens is removable and molded of tough acrylic.
  • Aluminum scale litho-printed black on white, enhances readability.
  • Red tipped aluminum pointer, rigidly mounted to helix is easy to see.
  • Wishbone assembly provides mounting for helix, helix bearings, and
    pointer shaft.
  • Jewel bearings provide virtually friction-free helix motion.
  • Helix is free to rotate in jewel bearings. It aligns with magnetic
    field of magnet to transmit pressure indications to pointer.
  • Zero adjustment screw, located behind the removable lens, eliminates
    tampering.
  • Range spring calibration clamp fixes live length of spring for proper
    gage calibration and is factory set and sealed.
  • Silicone rubber diaphragm allows accurate response to a broad range
    of temperatures and at extremely low pressure. Incorporates blow out area
    for overpressure protection.
  • Diaphragm support plates of lightweight aluminum on each side of the
    diaphragm minimize position or attitude sensitivity and help define pressure
    area.
  • Flat leaf range spring reacts to pressure on the diaphragm. Live length
    is adjustable for calibration. Small amplitude of motion minimizes inaccuracies
    and assures long life.
  • Low pressure tap connects to rear chamber.
  • Coil spring link provides a resilient connection between the diaphragm
    and the range spring.
  • Ceramic magnet mounted on a molded bracket at the end of the range
    spring rotates the helix without
    direct mechanical linkage.
  • High pressure tap connects with the front chamber through passageway
    in the plastic case and a sealing ring molded into the edge of the diaphragm.
  • Accuracy and value provides an excellent solution for OEM and user applications
