Diaphragm SealsDiaphragm seals are isolation devices which separate pressure gauges andother instruments from the process media while allowing the instrument tomeasure the process pressure. The service life of the instrument is greatlyextended, because it is protected from corrosion, clogging, freezing, orpulsation.LIQUID FILLINGSThe selection of the fill depends on the temperature expected in any givenapplication. Temperature ratings for available fillings are listed below.Glycerine 0 to 400ºFSilicone –40 to 600ºFSyltherm –40 to 750ºF12000MODEL 12000 MINISERVICEABLE RUBBERDIAPHRAGM SEALThe Model 12000 Serviceable MiniDiaphragm Seal is designed for gaugesand instruments with operating pressuresof 2500 psi with stainless and500 psi with PVC models.

ReferenceSELECTION AND USE OF A PRESSURE GAUGEWhen selecting a pressure gauge, it is important to consider the following factors to insure safety and accuracy:1. Pressure range2. Temperature range3. Conditions affecting wear of the system4. Case venting5. Pressure fluid <strong>com</strong>position6. Pressure fluid temperature7. Ambient conditions8. Method of mounting9. Required accuracyPRESSURE RANGE: A range of 2 times the operating pressure is re<strong>com</strong>mended for safety and extended gauge life. The operating pressure shouldbe limited to the middle 75% of range.TEMPERATURE RANGE: Ambient temperature for General Service (“J”) is -40° to 160°F. Ambient temperature for Severe Service (“J” & “X”),for Dry Gauges is -40° to 160°F and for Liquid Filled is 0° to 140°F.SHOCK, VIBRATION, PULSATION, OR CORROSIVE ATMOSPHERE CONDITIONS:Liquid Filled Gauges have a fillmaterial to lubricate the movement and reduce friction and wear. When used with a restrictor these gauges absorb vibration and dampen pressure shock andspikes. Liquid filling also prevents moisture or a corrosive atmosphere from affecting the gauge internals.CASE VENTING:Process (Series “P”) and Elite (Series “W”) have a internal diaphragm which <strong>com</strong>pensates for atmospheric changes that could affectthe calibration of the filled gauge. Severe Service (Series “J” & “X”) and 100mm (Series “HW”) liquid filled gauges have an elastomeric vent fill plug tipwhich can be easily cut to permit case venting.PRESSURE FLUID COMPOSITION: Since the sensing element of a pressure gauge may be exposed directly to the measured medium,consider the characteristics of this medium. It may be corrosive, it may solidify at various temperatures, or it may contain solids that will leave deposits inside thesensing element. For pressure fluids that will not solidify under normal conditions or leave deposits, a Bourdon Tube Gauge is acceptable Diaphragm Chemical Sealsshould be considered when gauge wetted parts are not <strong>com</strong>patible with the measured media. A chemical <strong>com</strong>patibility chart follows this section to aid in the selectionof the proper sensing element or diaphragm seal material.PRESSURE FLUID TEMPERATURE:Steam and other hot media may raise the temperature of the gauge <strong>com</strong>ponents above safe workinglimits of the sealed joints. In these cases it is re<strong>com</strong>mended that a syphon, cooling tower or chemical seal be used in conjunction with the pressure gauge DiaphragmSeals and remote capillary can also be considered for use with gauges or transducers which are subjected to very low or high ambient temperature.AMBIENT CONDITIONS: The normal ambient temperature range for <strong>Marsh</strong> Instruments gauges is -40° to 160°F (-40° to +71°C) for Dry Gauges, –4°to 140°F (–20° to 60°C) for Glycerine filled gauges, and –40° to 140 °F (–40° to 60° C) for Silicone filled gauges. The error caused by temperature changes is±0.3% per 18°F rise or fall, respectively. The reference temperature is 70°F (20°C). The correction is for the temperature of the gauge, and not the temperatureof the measured medium. Remote gauge mounting using a diaphragm seal and capillary line is one alternative for applications involving extreme ambient temperature.Moisture and weather effects must also be considered. Liquid Filled Gauges prevent condensation build up. For outdoor use, stainless steel, brass, orplastic cased gauges are re<strong>com</strong>mended.1-800-727-5646 SALES1-304-387-4417 SALES FAX64

PRESSURE GAUGE OPERATING PRINCIPLEBourdon tube pressure gauges are widely used inall branches of industry. The construction is simpleyet rugged, and operation does not requireany additional power source. The Bourdon tubeelement is directly exposed to the medium beingmeasured and is normal made of copper alloy(brass) or stainless steel as the applicationdemands.The Bourdon tube measuring element is made of athin walled tube that iseither bent into a semicircle(C-Shape tube) orspirally wound (coiledsafety tube). Whenpressure is applied tothe measuring systemthrough the pressureport, the pressure causesthe Bourdon tube tostraighten itself, thus causingthe end piece to moveupward (or downward forvacuum measurements). The movement of the end piece istransmitted via the link to the movement. The movement convertsthe linear motion of the Bourdon tube end piece to a rotationalmovement which in turn causes the pointer to indicate themeasured pressure.Bourdon tube pressure gauges are designed for the measurement of pressureand vacuum and are generally suitable for all clean and non-clogging liquid andgaseous media.Various types of Bourdon tubes are used. C-shape Bourdon tubes are typically used for ranges to 1,000 psi. Higherranges use coiled Bourdon tubes for safety.Bourdon tube pressure gauges are available to measure full vacuums, <strong>com</strong>pound and pressure ranges from 0-10 psi to0-20,000 psi with an accuracy from ±0.25% to ±3/2/3% of span (ASME Grade 3A to Grade B).ReferenceHOW THE DIAPHRAGM GAUGE WORKSDiaphragm gauges are sensitive instruments used in low pressureapplications not exceeding 10 psi. The diaphragm capsuleis an elastic metal sensing element <strong>com</strong>prised of twothin wall diaphragms whose sides are soldered together tomake the capsule.Whenever air or gas enters the intake port (gaugeconnection), it travels into the diaphragm capsule.As vacuum or pressure is applied to thediaphragm capsule, the walls of the capsuleexpand and contract in response to the changein pressure. This change is then transferred toa rotating rod and arm that rest on the outsideof the capsule. The rotating rod is connectedto a geared movement through a linkage system.Connected to a shaft, this system thendrives the pointer over a dial marked in appropriatepressure or vacuum units.65
