  • Brass wetted parts for measuring non-corrosive liquid and gas pressure
  • Circular dial is enclosed in an aluminum case that is certified IP52 for protection against dust and liquids
  • Measures pressure with dual scale (psi/kPa)/(Hg. vacuum/kPa)
  • Display accuracy is + or - 0.5% over the entire range of the gauge (ASME B40.100 Grade 2A)
  • Lower mount male connection with either 1/4" or 1/2" NPT rate

The Winters P3S 300 series pressure gauge with brass wetted parts has a circular dial enclosed in an aluminum case, and a lower mount male connection with NPT rate, and measures pressure with a dual scale (psi/kPa)/(Hg. vacuum/kPa) with a display accuracy of + or - 0.5%. The brass wetted parts are for measuring non-corrosive liquid and gas pressure. The circular dial is white aluminum, 4.5" (115 mm) or 6" (150 mm) in diameter, and enclosed in an aluminum case that is painted black and Ingress Protection certified IP52 for protection against dust and liquids. The front flange is polished stainless steel. The dial has an aluminum anodized black pointer that is micrometer-adjustable for ease of calibration, and the lens is glass for clarity. The gauge measures pressure with a dual scale of psi/kPa or Hg. vacuum/kPa. The gauge is accurate to + or - 0.5% over the entire range of the gauge, or American Society of Mechanical Engineers (ASME) B40.100 Grade 2A accuracy class. The male connection is mounted on the bottom of the gauge and has either a 1/4" or a 1/2" NPT (National Pipe Thread) rate. The ring for the gauge is polished stainless steel. The bourdon tube is phosphor bronze for pressure ranges up to 600 psi (4,137kPa) and stainless steel 316L for ranges over 600 psi (4,137kPa). The welding is a tin/copper alloy for pressure ranges up to 600 psi (4,137 kPa) and a silver alloy for pressure ranges over 600 psi (4,137kPa). The over-pressure limit is 30% for pressures up to 600 psi (4,137 kPa), 25% for pressures from 600 to 1,400 psi (4,137 to 9,653 kPa), and 15% for pressures over 1,400 psi (9,653 kPa). 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 boiler and control room applications with air, steam, oil, and fresh water.

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.
