Product Data Sheet00813-0100-4016, Rev HACatalog 2008 - 2009Rosemount 1199General InformationWHAT IS A DIAPHRAGM SEAL SYSTEM?A diaphragm seal system consists of a pressuretransmitter, one or two diaphragm seals, a fill fluid,and either a direct mount or capillary styleconnection. There is a need to make density or interfacemeasurements. The process medium may freeze or solidify inthe transmitter or impulse piping.PERFORMANCE CONSIDERATIONSDuring operation, the thin, flexible diaphragm and fillfluid separate the pressure sensing element of thetransmitter from the process medium. The capillarytubing or direct mount flange connects thediaphragm to the transmitter.When process pressure is applied, the diaphragm isdisplaced, transferring the measured pressurethrough the filled system, through the capillarytubing, to the transmitter element. This transferredpressure displaces the sensing diaphragm of thepressure transmitter. This displacement isproportional to the process pressure and isconverted electronically to an appropriate 4-20 mA,digital HART, or FOUNDATION fieldbus output signal.WHY USE DIAPHRAGM SEALS?Seal systems provide a reliable process pressuremeasurement and prevent the process medium fromcontacting the transmitter diaphragm.Transmitter/diaphragm seal systems should beconsidered when: The process temperature is outside of thenormal operating ranges of the transmitter andcannot be brought into those limits withimpulse piping. The process is corrosive and would requirefrequent transmitter replacement or specificexotic materials of construction. The process contains suspended solids or isviscous and may plug the impulse piping. The application requires the use of sanitaryconnections. There is a need for easier cleaning of theprocess from the connections to avoidcontamination between batches. There is a need to replace wet/ dry legs toreduce maintenance on applications wherethe reference leg is not stable or often needsto be refilled/drained.Pressure-4Attaching a diaphragm seal to a pressure transmitterchanges the performance of the transmitter. The sealsystem will have additional temperature effects andresponse time depending on the systemconfiguration. The performance of the entire systemneeds to be evaluated when specifying a seal systemfor a new application to ensure satisfactoryperformance when installed.Temperature EffectsSeal system temperature effects are caused bychanges in volume and density of the fill fluid in theseal system. Changes in volume are described asSeal Temperature Effects and occur when the fillfluid expands or contracts with fluctuations in theprocess or ambient temperature. This change in fillvolume drives a change in the internal pressure ofthe transmitter/seal system.The density of the fill fluid also changes withtemperature fluctuations. Changes in density aredescribed as Head Temperature Effect as theyrepresent a change in the head zero offset referencefrom initial installation. Both effects need to becombined to get the total temperature effects for aseal system.Seal Temperature EffectsThree primary factors affect the seal temperatureeffects of a diaphragm seal system: the diaphragmstiffness, the characteristics of the fill fluid, and thesystem volume.

Product Data Sheet00813-0100-4016, Rev HACatalog 2008 - 2009Rosemount 1199Diaphragm StiffnessFill FluidDiaphragm stiffness is a critical parameter affectingseal temperature effects. As the fill fluid expands orcontracts due to temperature changes, the sealdiaphragm stiffness will determine the amount of thevolume change that is absorbed by the sealdiaphragm and the amount exerted as back pressureon the transmitter sensor module. This backpressure acting upon the sensing diaphragm of thetransmitter represents the output temperature error.The expansion characteristics and the volume of fillfluid affect seal temperature effects. All fill fluidsexpand and contact with changes in temperature.The coefficient of thermal expansion defines theamount of change and is represented in cubiccentimeters of expansion per cubic centimeter of fluidvolume per degree Fahrenheit (cc/cc/F). The amountof expansion varies between fill fluids, as shown inFigure 2. Selecting a fill fluid with a smaller coefficientof thermal expansion will help minimize sealtemperature effects. Table 2 on page 15 provides thecoefficients of thermal expansion for the published fillfluids.Pressure creaseSmall DiameterSeal StiffnessCurve10-degreeincreaseFIGURE 1.
