NOSHOK 500 Series 304 Stainless Steel Liquid Filled Dial Indicating Pressure Gauge with Bottom Mount and 1/2" NPT Diaphragm Seal, 2-1/2" Dial, +/-1.5% Accuracy, 0-100 psi Pressure Range

The NoShok 500 series pressure gauge has stainless steel 316 wetted parts, a dry, fillable, or glycerin-filled 2.5" (63 mm) circular dial enclosed in a stainless steel 304 case, a lower mount male connection, and measures pressure with a single scale with an accuracy of + or - 1.5%. 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 2.5" diameter dial is filled with glycerin for protection against vibration and pulsation and has a transparent polyamide lens. The dial is white aluminum with black markings, is UV resistant, and has a balanced aluminum pointer with a black finish. The dial is accurate to + or - 1.5% over the entire range of the gauge, ASME B40.100 Grade A. The connection is mounted on the bottom of the gauge and has a 1/4" NPT (National Pipe Thread) rate. The gauge comes with a stainless steel 316 diaphragm seal with either a 1/4" or a 1/2" NPT rate process connection. The movement is stainless steel and nylon with highly polished bearing surfaces. 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 gauge has a safety relief disc on 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). 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.
