INTRODUCTION
The second refers to remote mounted diaphragm seal
process connections that have a capillary between the
chemical seal and the DPharp transmitter.
The major benefits are:
1. A Diaphragm Seal Mounting System
specifically designed for the DPharp Pressure
Transmitter
2. A "seamless" and rugged connection which
maintains structural integrity
a) 250 lbs. Shear load
b) Minimized fill volume for better thermal
characteristics
3) Flexible to adapt to a multitude of seals
a) Single flange which welds to upper
housing
■
■
This sales guide describes the chemical seal process
connections available from Yokogawa Corporation of
America. There are two distinct types of chemical seal
process connections. The first is the Direct Mount Seal
system (DMS) with the chemical seal attached as an
integral (close coupled) part of the DPharp body.
DMS
The Direct Mount Seal system, DMS, is a connection
system to mount various types of diaphragm seals
directly to the DPharp Pressure Transmitter. It was
originally designed to incorporate sanitary type seals,
and has been expanded to include flanged and extended
flanged diaphragm seals.
These options have allowed us to broaden our flangemounted (Level) transmitters with various fill fluids
and wetted-materials not currently available on the
EJA210A & 220A series. This also provides Yokogawa
the ability to offer custom type (not currently listed in
the price book) seals with varying barrel diameters,
diaphragm materials and connection sizes.
The DMS mounting flange maintains the same profile
as the DPharp flange, so the same bolt pattern and
mounting designs are used. This provides a "one piece"
design solution that insures the integrity of the DPharp
by maintaining maximum shear load capability. The
DMS also allows us to keep the fill fluid volume
minimized through the design, thereby reducing overall
temperature effect due to fluid expansion. This allwelded construction adds to the aesthetic as well as the
structural presentation of the product.

diaphragm seals. Price sheets for these seals are located
on 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 graphic
representation of the DMS
is referenced to the right.

REMOTE DIAPHRAGM SEALS
n Shorter
Overview
Remote diaphragm seals offer a cost-effective means of
preventing the process medium from coming in contact
with a pressure-sensing element. However, adding
remote seals to pressure sensing elements can have a
negative overall effect on system performance.
Temperature, thermal expansion coefficient of the fill
fluid, diaphragm size, spring constant, capillary length
and capillary diameter can all cause errors in
measurement and response time if not properly selected.
Operation
■
The system to be considered consists of a diaphragm
seal, a pressure transmitter, a capillary connection
between the seal and transmitter, and a fill fluid. This
diaphragm, capillary and fill fluid act as a medium to
relay the process pressures to the sensor in the
transmitter.
n High
temperature applications where the process fluid
temperature is beyond the acceptable specifications of
the transmitter sensing element
n Corrosive service where the requirements for materials
of construction is cost prohibitive
n To isolate the process for safety reasons
n Prevention of suspended solids from entering the cell
body or the impulse lines which could become plugged
and solidification may occur
n Requirement for sanitary connections
n Replacement of wet legs
n Ease of cleaning between batches to avoid
contamination
Seal Selection
Careful selection of seal size, capillary diameter,
capillary length and fill fluid must be considered to
optimize the total system performance, minimize the
effects of temperature and thermal expansion, and to
meet the process requirements. Overall variables to be
considered are:
n Larger diameter seals typically minimize temperature
effects

REMOTE DIAPHRAGM
SEAL APPLICATIONS
When to use a remote seal
A pressure is sensed by deflection of the thin film
diaphragm at the process connection. This deflection
causes a compression or expansion of the fill fluid,
which then is sensed at the transmitter by displacing
the transmitter element. This displacement is
proportional to the measured variable and is converted
to a 4-20 mA and/or digital output.
Model
Code
capillary lengths and smaller capillary ID help
reduce thermal expansion effects and response time
n When using a two seal system, diaphragm size,
capillary length and fill fluid should be the same for
both sides
n To reduce response time, select shorter capillary
lengths, larger capillary ID and less viscous fill fluid
n For vacuum service in level applications, the seal
should be mounted at or below the lower tap. Also a
fill fluid that is mixed with water should never be used
in a vacuum application
n Fill fluid should be selected to meet the most extreme
process variables and one which will not cause
contamination to the process in the event of seal
failure

The pressure head created by the fill fluid causes a preloading effect on the transmitter; therefore, the
calibration of zero must be elevated. The capillary
system in a level transmitter must be treated as a wet
leg where a negative pressure is created. This preloading effect is proportional to the height and specific
gravity of the fill fluid. Example: If a DP transmitter
with a full scale range of 400" H2O (which has a zero
elevation limit of 400" H2O) were to be used in a wet leg
application 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:
Diaphragm Size
The error induced in a system can be greatly affected by
differential temperature (between the process and the
fill fluid) and by the spring constant on the diaphragm
used. An error in a filled capillary system can be
calculated by the following equation:
Error ("H2O) = (DT) (Et) (Rs) (Vt)
∆T

Differential Temperature
This does not necessarily mean that a bigger diaphragm
is required. When a gauge pressure transmitter is
being used at pressures higher than 100 psig, a smaller
diaphragm can be used. Also, if a system has a large ƒT
between the process and ambient temperature but the
system is stable, such that this temperature difference
is constant, the two legs of the system will compensate
and the error can be zeroed out of the system. The
following is a quick pick chart for reference.

Example
A DP Cell is being used to measure level in a closed
tank. The range of the transmitter being used is 400"
H2O. Four inch diaphragm seals are being used with a
volume of 0.42, a spring constant of 40, and are placed
5’ apart with the transmitter being positioned 3’ below
the upper seal. The fill fluid is Silicone 200-10. Each
capillary has a volume of 0.053. The volume of the
transmitter cavity is 0.351. Ambient and Process
temperatures are shown.
Error= (∆T) (Et) (Rs) (Vt)
Capillary Length
Capillary length becomes a factor when using remote
seals on closed tank level applications. The pressure
generated by the vertical height of the fill fluid has an
effect on the zero suppression or elevation of the
transmitter. Force equals mass times acceleration,
which can be stated in the following manner when
specific gravity and vertical height of a fluid are known.
Pressure = (Ht) (Sg)
Ht The vertical height of the fill fluid in the capillary
Sg The specific gravity of the fill fluid

Verify that the distance between the seals is not outside
the range of the transmitter.
Dmax = Zmax
S.G.
Dmax = 400"/0.96 = 416.66" WC
Calculate the total thermal error introduced into the
system.
ErrorH = (220-95)(0.0006)(40)(0.42+0.053+0.351)
ErrorH = 2.472" WC for the high leg
ErrorL = (160-95)(0.0006)(40)(0.42+0.053+0.351)
ErrorL = 1.285" WC for the low leg
which produces a total differential error of +1.187" WC
NOTE: A 2.4" diaphragm with spring constant of 800
produces a total error of 23.73" WC.
Also, the two diaphragms are not located equal vertical
distances from the transmitter. Therefore the zero has
to be suppressed (5’)(12")(0.93) = 55.80" WC.
■
SUMMARY
In order to select an appropriate seal and capillary
combination, process conditions, installation
requirements and overall system performance must be
considered. The following is a list of questions in order
to take all effects into account. There is not a serve all
solution. Sometimes conditions occur which will require
sacrifice of one parameter in order to limit the effects on
the others. For instance, if there is a large temperature
change requiring smaller capillary ID, this will have a
greater effect on response time than a larger capillary
ID would.
2. Verify that the maximum vertical distance when
compensated with the specific gravity of the fill fluid
does not extend beyond the range of the transmitter
What is the highest temperature and lowest pressure
expected?
If the combination of temperature and pressure on the
fill fluid exceed the vapor pressure point, accuracy will
become unpredictable. Remember that as pressure
decreases, the temperature limits of the fill fluids are
lowered.
Is the process under vacuum?
Vacuum affects both the fill fluid selection and
mounting position of the transmitter. The temperature
limits of the fill fluid are lowered when exposed to a
vacuum. Also if the transmitter is not seeing positive
pressure, vaporization of the fill fluid is possible.
1. Verify that the fill fluid will operate at the highest
temperature and lowest pressure
2. Mount the transmitter at or below the lowest tap to
ensure a positive pressure on the measuring system at
all times
What is the measurement span?
Any error introduced into a system is greater when the
span is smaller. When the span is under 50" H2O, more
scrutiny should be placed on the selection criteria.
Remember on tank level applications, not to extend
beyond the maximum working range of the transmitter
when you compensate for the maximum vertical
distance of the fill fluid. Make sure that the
temperature effect is not a large percentage of span.
Questions to Ask and Points to Consider
What are the maximum process and ambient
temperature changes?
Temperature changes introduce errors in the system
through fill fluid expansion and from the diaphragm
spring constant. If this is a major factor, the following
should be chosen:
1. Larger diameter diaphragm with a lower spring
constant
2. Fill fluid with lower expansion rate
3. Shorter capillaries with smaller ID
How fast will the measured variable change?
Seals automatically introduce a delay in the system
reading. In a rapid changing process, the following
should be considered:
1. Shorter capillaries and/or larger ID
2. Less viscous fill fluid
Where will the transmitter be installed?
The longer the capillary the longer the response time
and 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 the
capillary fill fluid
What are the maximum pressure limits on the system?
Maximum pressure is limited to the connection
parameters. Flange ratings can be verified from ANSI
specifications. Threaded connections typically handle
higher pressures.
Is the process connection cleaned? With what type
solution?
Verify that the fill fluid will withstand the exposed
temperature (Sometimes a process tank or pipe is
cleaned at a higher temperature than the normal
process generates) and that the diaphragm material of
construction can withstand any corrosive exposure to
the introduced solution.
What are the maximum pressure limits on the system?
Maximum pressure is limited to the connection
parameters. Flange ratings can be verified from ANSI
specifications. Threaded connections typically handle
higher pressures.

Extended Flanged Diaphragm Seals (ACS 9906)
[DMS Capable]
These are similar to the flanged diaphragm seals, but also provide an extended
barrel for insertion of the diaphragm into "jacketed" tanks. These have a standard
barrel diameter of 2.85" (3" 150#) and 3.7" (4" 150#). These seals can be direct
mounted to the EJA transmitters.

Sanitary Diaphragm Seals (ACS 9908)
(DMS Capable)
Sanitary seals provide a connection that allows for quick disconnects from the
process for ease of cleaning and eliminates areas where bacterial growth can occur.
The sanitary In-line style seal provides a flow through diaphragm seal for gauge
pressure measurement. The In-line is the only member of the sanitary family
which cannot be direct mounted to the transmitters.

Flushing Rings
Flushing Rings, or calibration rings, are used when a process connection requires
cleaning without removal of the diaphragm seal. The standard flushing rings are
made from 316 Stainless Steel and come with single and dual 1/4" and 1/2" NPT
connections. These are selectable in the model configuration of most seals or
available as a separate item.
