Fittings: Fittings appear at the joints of many devices and are possible locations for gauges.

Because of this, pressure gauges can mount in a variety of locations. Machine and device operators need detailed information about the internal pressures of their machinery. You can find some air-pressure gauges that are backlit.

Analog readouts are the traditional dials with graduations, while digital readouts give users numerical representations of air pressure levels. Readout design: Digital and analog are the two main compressor readout designs.Larger dials provide visibility of small graduation lines. Face diameter: Compressor readouts often appear in dial form.Maximum pressure: Compressors put out a range of pressures that span from 15 pounds per square inch (psi) to over 1,000 psi.In addition to choosing a gauge according to its intended use, you can shop for gauges by: Pressure-testing equipment: Pressure-testing equipment can help test air-tight devices for structural integrity, and it can also help engineers and designers verify the strength of their products.Vacuum chambers: Vacuum chambers need specialized gauges to register low-pressure readings.Tire gauges help drivers to keep their tire pressure at the proper levels. Tire makers design their products for specific vehicles and road conditions, and they also recommend them for use at certain air pressures. Tire-pressure readers: Vehicle tires can come in many shapes and sizes.Manufacturers design compressors to operate within specific ranges, and gauges can help you to monitor, adjust, and track those values. Air compressors: Power tools often use compressed air as an energy source, and compressors are the instruments that make this possible.HVAC systems use liquids and gases that need to be maintained at specific pressures, and pressure gauges give you a way to monitor those pressures. HVAC systems: Heating, ventilation, and air conditioning (HVAC) systems are responsible for maintaining comfortable internal conditions in commercial and personal buildings.You can use them to monitor and measure air pressure with a variety of instruments and equipment. What are some applications for air-pressure gauges?Īir-pressure measurement tools have wide-ranging applications. Some air-pressure gauges might suit your needs better than others. These measurement devices can be used in personal or professional applications. When main pressure exceeds 80 psi (551 kPa), an approved pressure-reducing valve conforming to ASSE 1003 or CSA B356 shall be installed on the domestic water branch main or riser at the connection to the water-service pipe.Air-pressure gauges give you the ability to read and record air pressure data from a variety of devices.

The static water pressure shall be not greater than 80 psi (551 kPa). Chapter 29 Water-supply and Distribution Section P2903 Water Supply System The water used for tests shall be obtained from a potable water source. This pressure shall be held for not less than 15 minutes. Upon completion of the water-supply system or a section of it, the system or portion completed shall be tested and proved tight under a water pressure of not less than the working pressure of the system or, for piping systems other than plastic, by an air test of not less than 50 psi (345 kPa). This pressure shall be held without introduction of additional air for a period of 15 minutes.

The portion under test shall be maintained at a gauge pressure of 5 pounds per square inch (psi) (34 kPa) or 10 inches of mercury column (34 kPa). Either test shall be applied to the drainage system in its entirety or in sections after rough piping has been installed, as follows: International Residential Code 2012 Chapter 25 Plumbing Administration Section P2503 Inspection and TestsĭWV systems shall be tested on completion of the rough piping installation by water or for piping systems other than plastic, by air with no evidence of leakage. And you have to maintain the pressure for 15 minutes.įor air testing drain-waste-vent (DWV) systems, you have to maintain 5 psi for 15 minutes.Ĭontact your local government, to find out what they require. You have to test using the maximum working pressure (80 psi) of water, or 50 psi of air. According to IRC, for supply system testing.
