Product Description

The Dwyer series SGT pressure gauge has brass wetted parts, a 2.5" (63 mm) circular dial enclosed in a stainless steel 304 case, a lower mount male connection, and measures pressure with a dual scale (psi/kPa)/(Hg. vacuum/kPa) with an accuracy of + or - 1.6%. The brass wetted parts are for measuring non-corrosive liquid and gas pressure. The stainless steel 304 case provides corrosion resistance and is Ingress Protection certified IP55 for protection against dust and liquids. The gauge is liquid-fillable to protect against vibration and pulsation, and has a clear thermoplastic lens for durability. The gauge measures pressure with a dual scale in psi/kPa or Hg. vacuum/kPa with an accuracy of + or - 1.6% over the entire range of the gauge, American Society of Mechanical Engineers (ASME) B40.100 Grade A accuracy class. The male connection is mounted on the bottom of the gauge and has a 1/4" NPT (National Pipe Thread) rate. The pressure limit is 130% of full scale range. The ambient temperature for the gauge is -4 to 140 degrees F (-20 to 60 degrees C). The maximum process temperature 248 degrees F (120 degrees C).

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.

Dwyer Instruments manufactures measurement and control instruments, including pressure gauges, flow meters, level instrumentation, temperature instrumentation, and air quality monitors. The company, founded in 1931, is headquartered in Michigan City, IN.
