Dwyer 2-5205-5PSI Minihelic II Differential Pressure Gauge 0-5 PSI
Designed For Panel Mounting in a 2-5/8″ Diameter Hole. Pressure Connections Are Barbed. Dwyer 2-5205 Minihelic II Differential Pressure Gauge
The Dwyer 2-5205 Differential Pressure Gauge has barbed connections and a range of 0-5 psi. Combining clean design , small size and low cost with enough accuracy for all but the most demanding applications our Minihelic® II gauge offers the latest in design Features for a dial type differential pressure gauge. It is our most compact gauge but is easy to read and can safely operate at total pressures up to 30 psig. The Minihelic® II gauge 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 gauge 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 gauge. With removable lens and rear housing, the gauge may be easily serviced at minimum cost. With the housing molded from mineral and glass filled nylon and the lens molded from acrylic, the gauge will withstand rough use and exposure as well as high total pressure. The 5% accuracy and low cost of the Minihelic® II gauge 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 gauge, the Minihelic® II gauge finds many end use applications on large stationary engines, compressors, ventilators, and air handling units. The Minihelic® II gauge is suitable for many of the same applications as the Magnehelic® gauge where the greater accuracy, sensitivity, and higher and lower differential pressure ranges of the Magnehelic® gauge are not required.
