Differential pressure switch/gage combines the time proven Minihelic II differential pressure gage with two SPDT switching set points. The Mini-Photohelic switch/gage is designed to measure and control positive, negative, or differential pressures consisting of non-combustible and non-corrosive gases. Gage reading is independent of switch operation. Switching status is visible by LED indicators located on the front and rear of the gage. Set points are adjusted with push buttons on back of unit. This extremely compact switch/gage is ideal for fume hoods, dust collection, pneumatic conveying and clean room applications.

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 referenc...

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.
