The WIKA differential low pressure gauge has a circular dial that is 4" in diameter and is enclosed in a thermoplastic case with a polycarbonate window for increased durability in low temperature environments. The gauge measures pressure from 0.02 to 50 inch water column (inWC) and is accurate to + or - 3 percent of span over the entire range of the gauge. The female connection is a hosed barb that is made of plastic for increased durability. The gauge can be mounted and dismounted easily without the use of tools. The low pressure gauge is suitable for measuring differences of pressure in isolation chambers and for monitoring blowers and ventilators.
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.
