Direct Mount Seal System and Diaphragm Seals

� INTRODUCTION

This sales guide describes the chemical seal processconnections available from Yokogawa Corporation ofAmerica. There are two distinct types of chemical sealprocess connections. The first is the Direct Mount Sealsystem (DMS) with the chemical seal attached as anintegral (close coupled) part of the DPharp body.

The second refers to remote mounted diaphragm sealprocess connections that have a capillary between thechemical seal and the DPharp transmitter.

� DMS

The Direct Mount Seal system, DMS, is a connectionsystem to mount various types of diaphragm sealsdirectly to the DPharp Pressure Transmitter. It wasoriginally designed to incorporate sanitary type seals,and has been expanded to include flanged and extendedflanged diaphragm seals.

These options have allowed us to broaden our flange-mounted (Level) transmitters with various fill fluidsand wetted-materials not currently available on theEJA210A & 220A series. This also provides Yokogawathe ability to offer custom type (not currently listed inthe price book) seals with varying barrel diameters,diaphragm materials and connection sizes.

The DMS mounting flange maintains the same profileas the DPharp flange, so the same bolt pattern andmounting designs are used. This provides a "one piece"design solution that insures the integrity of the DPharpby maintaining maximum shear load capability. TheDMS also allows us to keep the fill fluid volumeminimized through the design, thereby reducing overalltemperature effect due to fluid expansion. This all-welded construction adds to the aesthetic as well as thestructural presentation of the product.

Included with this release is an overview on the use ofdiaphragm seals. Price sheets for these seals are locatedon the YCA Electronic Price Book.

Benefits:The obvious advantage to using a direct mount system is the elimination of capillaries. This helps with the overall temperature effect and necessity to mount and care for the capillaries.Some of the other benefits of the direct mount system are structural integrity and ease of installation and removal and replacement. A graphicrepresentation of the DMSis referenced to the right.Please keep in mind that this DMS "flange" uses thesame bolt pattern as theexisting DP Harp seriestransmitters.

The major benefits are:1. A Diaphragm Seal Mounting Systemspecifically designed for the DPharp PressureTransmitter2. A "seamless" and rugged connection whichmaintains structural integrity

a) 250 lbs. Shear loadb) Minimized fill volume for better thermal

characteristics3) Flexible to adapt to a multitude of sealsa) Single flange which welds to upper

housing

� REMOTE DIAPHRAGM SEALS

Overview

Remote diaphragm seals offer a cost-effective means ofpreventing the process medium from coming in contactwith a pressure-sensing element. However, addingremote seals to pressure sensing elements can have anegative overall effect on system performance.Temperature, thermal expansion coefficient of the fillfluid, diaphragm size, spring constant, capillary lengthand capillary diameter can all cause errors inmeasurement and response time if not properly selected.

Operation

The system to be considered consists of a diaphragmseal, a pressure transmitter, a capillary connectionbetween the seal and transmitter, and a fill fluid. Thisdiaphragm, capillary and fill fluid act as a medium torelay the process pressures to the sensor in thetransmitter.

A pressure is sensed by deflection of the thin filmdiaphragm at the process connection. This deflectioncauses a compression or expansion of the fill fluid,which then is sensed at the transmitter by displacingthe transmitter element. This displacement isproportional to the measured variable and is convertedto a 4-20 mA and/or digital output.

Seal Selection

Careful selection of seal size, capillary diameter,capillary length and fill fluid must be considered tooptimize the total system performance, minimize theeffects of temperature and thermal expansion, and tomeet the process requirements. Overall variables to beconsidered are:nLarger diameter seals typically minimize temperature

effects

nShorter capillary lengths and smaller capillary ID helpreduce thermal expansion effects and response time

nWhen using a two seal system, diaphragm size,capillary length and fill fluid should be the same forboth sides

nTo reduce response time, select shorter capillarylengths, larger capillary ID and less viscous fill fluid

nFor vacuum service in level applications, the sealshould be mounted at or below the lower tap. Also afill fluid that is mixed with water should never be usedin a vacuum application

nFill fluid should be selected to meet the most extremeprocess variables and one which will not causecontamination to the process in the event of sealfailure

� REMOTE DIAPHRAGM SEAL APPLICATIONS

When to use a remote seal

nHigh temperature applications where the process fluidtemperature is beyond the acceptable specifications ofthe transmitter sensing element

nCorrosive service where the requirements for materialsof construction is cost prohibitive

nTo isolate the process for safety reasonsnPrevention of suspended solids from entering the cell

body or the impulse lines which could become pluggedand solidification may occur

nRequirement for sanitary connectionsnReplacement of wet legsnEase of cleaning between batches to avoid

contamination

Fill Fluid

When selecting fill fluid consider four criteria1. Do the temperature limits of the fill fluid cover the

process and ambient ranges?2. Is this a sanitary application (food grade fill)?3. Is the process Oxygen service (inert fill)?

Diaphragm Size

The error induced in a system can be greatly affected bydifferential temperature (between the process and thefill fluid) and by the spring constant on the diaphragmused. An error in a filled capillary system can becalculated by the following equation:

Error ("H2O) = (DT) (Et) (Rs) (Vt)

∆T The differential temperature changeEt The coefficient of thermal expansion of the fill fluidRs The diaphragm spring constantVt The volume of the fill fluid subjected to temperature

change

The following graph shows the comparison of twodifferent diaphragm sizes and their effect on total errorinduced.

This does not necessarily mean that a bigger diaphragmis required. When a gauge pressure transmitter isbeing used at pressures higher than 100 psig, a smallerdiaphragm can be used. Also, if a system has a large ƒTbetween the process and ambient temperature but thesystem is stable, such that this temperature differenceis constant, the two legs of the system will compensateand the error can be zeroed out of the system. Thefollowing is a quick pick chart for reference.

Capillary Length

Capillary length becomes a factor when using remoteseals on closed tank level applications. The pressuregenerated by the vertical height of the fill fluid has aneffect on the zero suppression or elevation of thetransmitter. Force equals mass times acceleration,which can be stated in the following manner whenspecific gravity and vertical height of a fluid are known.

Pressure = (Ht) (Sg)

Ht The vertical height of the fill fluid in the capillarySg The specific gravity of the fill fluid

The pressure head created by the fill fluid causes a pre-loading effect on the transmitter; therefore, thecalibration of zero must be elevated. The capillarysystem in a level transmitter must be treated as a wetleg where a negative pressure is created. This pre-loading effect is proportional to the height and specificgravity of the fill fluid. Example: If a DP transmitterwith a full scale range of 400" H2O (which has a zeroelevation limit of 400" H2O) were to be used in a wet legapplication and the wet leg has a specific gravity of 0.9,the maximum height of the wet leg would be 444" H2O.This applies to filled capillary systems:

Dmax = ZmaxS.G.

Dmax Maximum vertical distance betweendiaphragm sealsZmax Maximum zero elevation of the transmitterS.G. Specific gravity of the fill fluid

Example

A DP Cell is being used to measure level in a closedtank. The range of the transmitter being used is 400"H2O. Four inch diaphragm seals are being used with avolume of 0.42, a spring constant of 40, and are placed5’ apart with the transmitter being positioned 3’ belowthe upper seal. The fill fluid is Silicone 200-10. Eachcapillary has a volume of 0.053. The volume of thetransmitter cavity is 0.351. Ambient and Processtemperatures are shown.

NOTE: A 2.4" diaphragm with spring constant of 800produces a total error of 23.73" WC.Also, the two diaphragms are not located equal verticaldistances from the transmitter. Therefore the zero hasto be suppressed (5’)(12")(0.93) = 55.80" WC.

� SUMMARY

In order to select an appropriate seal and capillarycombination, process conditions, installationrequirements and overall system performance must beconsidered. The following is a list of questions in orderto take all effects into account. There is not a serve allsolution. Sometimes conditions occur which will requiresacrifice of one parameter in order to limit the effects onthe others. For instance, if there is a large temperaturechange requiring smaller capillary ID, this will have agreater effect on response time than a larger capillaryID would.

Questions to Ask and Points to Consider

What are the maximum process and ambienttemperature changes?Temperature changes introduce errors in the systemthrough fill fluid expansion and from the diaphragmspring constant. If this is a major factor, the followingshould be chosen: 1. Larger diameter diaphragm with a lower springconstant2. Fill fluid with lower expansion rate3. Shorter capillaries with smaller ID

How fast will the measured variable change?Seals automatically introduce a delay in the systemreading. In a rapid changing process, the followingshould be considered:1. Shorter capillaries and/or larger ID2. Less viscous fill fluid

Where will the transmitter be installed?The longer the capillary the longer the response timeand a larger increase in error due to thermal effects.Always mount the transmitter as close as is practical.Always remember:1. Compensate for the effect of vertical height on thecapillary fill fluid

2. Verify that the maximum vertical distance whencompensated with the specific gravity of the fill fluiddoes not extend beyond the range of the transmitter

What is the highest temperature and lowest pressureexpected?If the combination of temperature and pressure on thefill fluid exceed the vapor pressure point, accuracy willbecome unpredictable. Remember that as pressuredecreases, the temperature limits of the fill fluids arelowered.

Is the process under vacuum?Vacuum affects both the fill fluid selection andmounting position of the transmitter. The temperaturelimits of the fill fluid are lowered when exposed to avacuum. Also if the transmitter is not seeing positivepressure, vaporization of the fill fluid is possible.1. Verify that the fill fluid will operate at the highesttemperature and lowest pressure2. Mount the transmitter at or below the lowest tap toensure a positive pressure on the measuring system atall times

What is the measurement span?Any error introduced into a system is greater when thespan is smaller. When the span is under 50" H2O, morescrutiny should be placed on the selection criteria.Remember on tank level applications, not to extendbeyond the maximum working range of the transmitterwhen you compensate for the maximum verticaldistance of the fill fluid. Make sure that thetemperature effect is not a large percentage of span.

What are the maximum pressure limits on the system?Maximum pressure is limited to the connectionparameters. Flange ratings can be verified from ANSIspecifications. Threaded connections typically handlehigher pressures.

Is the process connection cleaned? With what typesolution?Verify that the fill fluid will withstand the exposedtemperature (Sometimes a process tank or pipe iscleaned at a higher temperature than the normalprocess generates) and that the diaphragm material ofconstruction can withstand any corrosive exposure tothe introduced solution.
