Ashcroft® industrial pressure gaugeshave earned a reputation for depend-ability as a mainstay in the marketplacefor over 150 years. Meeting the require-ments of ASME B40.1-1991, Ashcroftindustrial pressure gauges are offeredin a wide assortment of dial sizes, casestyles and wetted parts materials.
These gauges have been engineeredfor general service applications such aslow-pressure applications from 10 inch-es of water, and hydraulic and refrigera-tion service. Other industrial pressuregauges measure differential pressure,while Ashcroft duplex pressure gaugesmeet requirements for indication of tworelated pressures with a single gauge.The Ashcroft industrial gauge family
also includes the Reid vapor test gaugespecifically designed for testing volatilepetroleum liquids using the vapor testprocedure prescribed by ASTM D-323.Ashcroft Christmas tree gauges aredesigned specifically for use in the oilfields.
Ashcroft industrial pressure gaugesare available in a variety of sizes andmaterials to meet the demands of theindustrial marketplace. When selectingan Ashcroft industrial pressure gauge,consider these seven steps:
— Ashcroft industrialpressure gauges are available in awide selection of Bourdon tube andsocket materials to fit your application.
— available withranges as low as 10 inches of waterthrough 20,000 psi, Ashcroft industrialpressure gauges have been designedto meet your application needs.
t — available incase materials of stainless steel,black epoxy-coated aluminum andphenolic, these gauges have beendesigned to withstand the mostdemanding environments. Most areavailable with an optional built-inthrottle plug to help protect againstpressure surges or spikes.
— all general service type industrial gauges areoffered with a 1% ASME Grade 1Aaccuracy. Ashcroft Types 5503 and5509 gauges have standard accura-cies of 1.6% and 2.5% respectively.Low-pressure bellows gauges and allother industrial gauges are offered witha 2/1/2% ASME Grade A accuracy.
— available with dial sizesfrom 21⁄2 through 81⁄2 inches, Ashcroftindustrial gauges come in sizes tomeet your space requirements withoptimum gauge readability.
— availability includes, but is not limited to 1⁄4 NPT, 1⁄2 NPT,BSP, JIS and SAE connections.
— depending on the type, Ashcroft gauges areavailable for stem, surface or flushmounting.
Consult ASME B40.1 for guidance ingauge selection
WARNING: To prevent misapplication,pressure gauges should be selectedconsidering media and ambient operat-ing conditions. Improper application canbe detrimental to the gauge, causingfailure and possible personal injury orproperty damage. The information con-tained in this bulletin is offered as aguide to assist in making the properselection of a pressure gauge.Additional information is available fromDresser Instrument Division. Pressure Ranges:As recommended by ASME B40.1,select a gauge with a full scale pressurerange of approximately twice the nor-mal operating pressure. The maximumoperating pressure should not exceedapproximately 75% of the full scalerange. Failure to select a gauge rangewithin these criteria may ultimately re-sult in fatigue failure of the Bourdon tube.Operating Conditions:The operating conditions to which agauge will be subjected must be con-sidered. If the gauge will be subjectedto severe vibration and/or pressure pul-sation, a liquid-filled gauge with a throt-tle plug will be necessary to obtain nor-mal product life. With the exception ofTypes 5503 and 5509 industrial pres-sure gauges cannot be liquid-filled.When pulsation or vibration are present
on a gauge that cannot be liquid-filled,the gauge should be isolated from theprocess using flexible line assembly.
To ensure long life and accurate read-ings, pressure gauges should not beexposed to process or ambient temper-atures over 150°F. Long term exposureto temperatures in excess of 150°F maycause discoloration of dials as well ashardening of elastomeric case seals.Soft-soldered, silver-brazed and weldedpressure joints are rated at 250°F maxi-mum, 450°F maximum and 750°F max-imum respectively. Plastic gauge cases,including phenolic, should not beexposed to temperatures in excess of250°F. Maximum recommended servicetemperatures for gauge windows are asfollows: 350°F for plain glass; 270°F forpolycarbonate; 200°F for laminatedsafety glass; and 180°F for acrylic.
Heat and cold affect accuracy of indi-cation. A general rule of thumb for drygauges is 0.5% of full scale change forevery 40°F change from 75°F. Above250°F there may exist very significanterrors in indication.
Proper selection of the bourdon,diaphragm or bellows system materialis dependent on the process fluid towhich the system will be subjected. Ifthe correct material is not available, theuse of a diaphragm seal may be neces-sary to protect the system from theprocess fluid. Liquid-filled gauges withthrottle plugs are recommended for thedischarge side of positive displacementpumps.
Pressure Elements:Available in a wide variety of materials,including: phosphor bronze, alloy steel,316 stainless steel and K Monel.Cases:Depending on the type, Ashcroft indus-trial gauges are available in aluminum,stainless steel or cast iron case materi-als. With the exception of AshcroftTypes 5503 and 5509, industrialgauges are not weatherproof or her-metically sealed. They are furnishedstandard with a pressure-relief plug.Rings:The ring, which retains the window, isbayonet (cam), or slip depending on thetype number.Movements:Movements are designed and materialsof construction selected to reduce fric-tion and extend wear life.Dials:Dials are uniformly graduated, and havehighly legible markings depending onthe gauge type. Industrial gauges areoffered with brushed aluminum dialswith black markings or white dials withblack markings.Windows:Depending on the size and type,Ashcroft industrial gauges are availablewith acrylic, shatterproof glass or glasswindows.Pointers:Depending on the type, Ashcroft indus-trial gauges are available with adjustableor fixed pointers.

The media being measured must becompatible with the wetted parts of thepressure instrument. To use the chartbelow, locate the media whose pressureis to be measured and select a suitablematerial from those available. This is asimplified chart and assumes the media
temperature is below 200°F except formedia with an * which must be below100°F. Throttling devices and a liquidfilled instrument are recommended inapplications with pulsation or vibration.These recommendations are only aguide, as service life is dependent on
temperature, concentrations, catalyststhat may be added, or other conditionsbeyond our control. Consult Stratford,CT, customer service for specific applica-tions and for any media not listed.
