The WIKA standard digital pressure gauge has stainless steel 316L wetted parts, which resist corrosion to chloride, and has a digital display that is 4 1/2" in diameter for clear readings and is enclosed in a stainless steel case that resists corrosion. The gauge measures pressure up to 10,000 pounds per square inch (psi), or equivalent measures in kilopascals (kPa) and bar, and is accurate to + or - 0.25 percent of span over the entire range of the gauge, or American Society for Mechanical Engineering (ASME) B40.100 Grade 3A accuracy class. The male connection is mounted on the bottom of the gauge, and has a 1/4" National Pipe Thread (NPT) rate. This gauge is suitable for use with hydraulic and pneumatic systems, compressors, and pumps.
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.
WIKA Instrument Corporation is a global manufacturer of pressure and temperature measurement instruments, including pressure gauges, diaphragm seals, pressure transmitters, and thermometers, that meet International Organization for Standardization (ISO) standards for quality assurance. The company, founded in 1946, is headquartered in Lawrenceville, GA.
