The WIKA process pressure gauge has copper alloy wetted parts, which resist corrosion against salty liquids, and a circular dial that is enclosed in a thermoplastic case for increased durability, particularly in low temperature environments. The gauge measures pressure from 15 pounds per square inch (psi) to 1,000 psi, and is accurate to + or - 0.5 percent of span over the entire range of the gauge, or American Society for Mechanical Engineering (ASME) B40.100 Grade 2A accuracy class. The male connection is mounted on the bottom of the gauge and comes with a choice of a 1/4" or 1/2" National Pipe Thread (NPT) rate. This gauge is suitable for use in corrosive environments in process industries, such as chemical or petrochemical applications, mining applications, and power stations.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 gauge...
