The stainless steel 316 wetted parts and the stainless steel 304 case provide corrosion resistance. The gauge measures pressure with a single psi or Hg. vacuum scale. The dial comes in 1.5" (40 mm), 2.5" (63 mm) diameters, 4" (100 mm), and 6" (152 mm) diameters. The dial can be dry, dry/fillable, or liquid filled, depending upon the model. The specifications for each type of gauge vary according to the gauge size. The dial lens comes in three different forms of transparent materials for strength and clarity. The lens on the 1.5" and 4" diameter dials is instrument glass. The lens on the 2.5" diameter dial is transparent polyamide. The lens on the 6" dial is laminated safety glass. The dial is white aluminum with black markings and is UV resistant. The pointer type varies depending upon the dial size. The 1.5" dial has a black finished aluminum pointer. The 2.5" and 4" dials have a balanced aluminum pointer with a black finish. The 6" dial also has a balanced aluminum pointer with a black finish, and it is micrometer-adjustable. Gauge accuracy varies according to gauge size. The 1.5" dial is accurate to + or - 2.5% over the entire range of the gauge, American Society of Mechanical Engineers (ASME) B40.100 Grade B accuracy class. The 2.5" gauge is accurate to + or - 1.5% over the entire range of the gauge, ASME B40.100 Grade A accuracy class. The 4" and 6" gauges are accurate to + or - 1% over the entire range of the gauge, ASME B40.100 Grade 1A accuracy class. All gauges come with either a lower mount or center back connection. The connection for the 1.5" gauge is a 1/8" NPT (National Pipe Thread) rate. The connection for the 2.5" gauge is a 1/4" NPT rate. The connection for the 4" and 6" gauges is a 1/2" NPT rate. The movement for all gauges is stainless steel with highly polished bearing surfaces. The 1.5" and 2.5" gauge movement also includes nylon. The movement for the 4" gauge and 6" gauge also includes an internal zero stop to protect the gauge system. The bourdon tube is a stainless steel 316 C-Type tube for all gauges with a pressure range up to 600 psi. For gauges with pressure ranges above 600 psi, the bourdon tube is a coiled safety tube. The 2.5" gauge has a safety relief disc on the top of the case. The 4" and 6" gauges have a safety relief disc on the back and the top of the case. The gauge operates in fluctuating pressure up to 60% of the dial range and in static pressure up to 90% of the dial range. The ambient temperature for the gauge is -40 to 140 degrees F (-40 to 60 degrees C). The media temperature range is -40 to 212 degrees F (-40 to 100 degrees C) for the 1.5" and 2.5" gauges. The media temperature range is -40 to 392 degrees F (-40 to 200 degrees C) for the 4" and 6" gauges. This pressure gauge is suitable for chemical plants, petro-chemical refineries, biomedical, pharmaceutical, food and beverage processing, offshore oil platforms, paper mills, salt mines, fertilizer plants, and shipboard applications. 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. NoShok manufactures temperature and pressure measurement instruments, including pressure gauges, transducers and indicators, level transmitters, temperature switches and transmitters, and bimetal thermometers. The company, founded in 1967, is headquartered in Berea, OH. Additional Information Manufacturer: NOSHOK, Inc.
