Winters PLP Series Stainless Steel 304 Low Pressure Gauge, 0-15" Water Vacuum, 2-1/2" Dial Display, +/- 1.6% Accuracy, 1/4" NPT Bottom Mount

The Winters PLP series pressure gauge with stainless steel 316 wetted parts and a lower mount connection has a circular dial enclosed in a steel case, and measures pressure with a single or dual scale with an accuracy of + or - 1.6%. The stainless steel 316 wetted parts provide corrosion resistance. The stainless steel 304 case is Ingress Protection certified IP52 for protection against dust or liquids. The circular dial comes in 2.5" (63 mm) or 4" (100 mm) diameters. The dial is white aluminum with black and red markings. It has an aluminum, anodized black, pointer and the lens is polycarbonate for high impact resistance. The lens ring is steel. The gauge measures pressure with a single water vacuum scale or a dual scale of psi/kPa or water/oz. The gauge is accurate to + or - 1.6% of full scale value. The male connection is mounted on the bottom of the gauge and has a 1/4" NPT (National Pipe Thread) rate. The welding is tungsten inert gas (TIG) for strength. The over-pressure limit is 30% of full scale value. The working pressure is a maximum of 75% of full scale value. The operating temperature is -40 to 150 degrees F (-40 to 65 degrees C). This pressure gauge is suitable for vacuum pumps, air compressors, air filters, gas burners, vacuum ovens, suction regulators, and respirators.

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.

Winters Instruments manufactures pressure gauges, thermometers, diaphragm seals, pressure transmitters, and switches. The company, founded in 1953, is headquartered in Toronto, Canada.
