Dwyer Minihelic II Series 2-5000 Differential Pressure Gauge, Range 0-100"WC

Model: 2-5100   |    Mpn: 2-5100   |    PartNumber: 2-5100   |   Asin: B009PC671K

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.

Features

  • Jewel bearings provide virtually friction-free helix motion
  • 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
  • Combining High Accuracy, Compactness, Dependability, and Low Cost

Dwyer Capsuhelic Series 4000 Differential Pressure Gauge, Range 0-6"WC

Model: 4006   |    Mpn: 4006   |    PartNumber: 4006   |   Asin: B009P8RINU

The Dwyer Capsuhelic series 4000 differential pressure gauge with an aluminum case has a circular 4" (100 mm) dial, and four female 1/4" NPT rate connections, and measures pressure with single scale in inch water column (WC), mm WC, cm WC, psid, or kPa with a display accuracy of + or - 3 or 4%. The die-cast aluminum case with impregnated hard coating is for measuring air and compatible gases and oil-based liquids. The circular dial is 4" in diameter and measures pressure with a single scale in inch water column (WC), mm WC, cm WC, psid, or kPa. The pressure being measured is held within a capsule in the gauge, which permits the use of the gauge on system pressures of up to 500 psig, even with differentials less than 0.1 in WC. The gauge accuracy is + or - 3% of full scale at 70 degrees F (21.1 degrees C) with + or - 4% of full scale on some models. The pressure limits are -20" Hg. to 500 psig. The temperature limit is 20 to 200 degrees F (-6.67 to 93.3 degrees C). Four female connections with 1/4" NPT (National Pipe Thread) rate provide for vertical mounting of the gauge. The connections are paired with one high and low pressure pair of taps on top for air and gas and one high and low pressure pair on bottom for liquids. This gauge is suitable as a readout device when measuring flowing fluids, pressure drop across filters, liquid levels in storage tanks, and other applications involving pressure, vacuum, or differential pressure. The gauge comes with two 1/4" NPT plugs for duplicate pressure taps, four flush mounting adapters with screws, and four surface mounting screws.

Pressure gauges are instruments used to measure the pressure of a gas or liquid inside a vessel and, often, to help ensure the optimal amount of pressure for a given application. Pressure gauges can range from everyday instruments, such as those used to measure the air pressure in a car or bicycle tire, to highly accurate gauges used in mechanical and industrial processing. Most often, pressure gauges measure pressure relative to another reference. For instance, gauge pressure measures pressure relative to ambient air. An example of a pressure gauge measuring relative to ambient air is a tire pressure gauge or a blood pressure gauge. Differential pressure is the difference in pressure between two points, such as when measuring liquid flow along various points in a pipeline. An absolute pressure gauge measures pressure relative to a perfect vacuum, such as an atmospheric or barometric pressure gauge. All types of pressure gauges include either a male or a female mount to connect to the vessel where pressure is being measured, and display results on a dial with varying increments of measure across a given range.

Dwyer Instruments manufactures measurement and control instruments, including pressure gauges, flow meters, level instrumentation, temperature instrumentation, and air quality monitors. The company, founded in 1931, is headquartered in Michigan City, IN.

What's in the Box? Dwyer Capsuhelic series 4000 differential pressure gauge 1/4" NPT plugs (2) Flush mounting adapters with screws (4) Surface mounting screws (4)

The force for pushing or pulling open a door or gate other than fire doors shall be as follows: 1. Interior hinged doors and gates: 5 pounds maximum. 2. Sliding or folding doors: 5 pounds maximum. These forces do not apply to the force required to retract latch bolts or disengage other devices that hold the door or gate in a closed position. Advisory 404.2.9 Door and Gate Opening Force. The maximum force pertains to the continuous application of force necessary to fully open a door, not the initial force needed to overcome the inertia of the door. It does not apply to the force required to retract bolts or to disengage other devices used to keep the door in a closed position. OPERATING INSTRUCTIONS : 1. Set the top (small) o-ring located on the plunger rod on zero, down against the instrument's flange; or set the o-ring on the desired force. 2. Holding the instrument firmly, press slowly against the door at a point approximately handle-high, and 30 inches away from the door's hinges. 3. Read the amount of force required to open the door on the plunger scale closest to the bottom of the small o-ring. A must have for determining ADA compliance!

Dwyer Minihelic II Series 2-5000 Differential Pressure Gauge, Range 0-60"WC

Model: 2-5060   |    Mpn: 2-5060   |    PartNumber: 2-5060   |   Asin: B009PC6PLW

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.

Features

  • Jewel bearings provide virtually friction-free helix motion
  • 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
  • Combining High Accuracy, Compactness, Dependability, and Low Cost
