2Performance
The performance of a remote diaphragm seal is determined by how
accurately it can transfer a pressure signal from the process fluid to the
transmitter sensor.
The spring rate of a transmitter diaphragm is many times greater than
the spring rate of a remote seal diaphragm. Therefore, the influence of
the capillary and seal on transmitter linearity, hysteresis, and
repeatability is usually slight. Temperature variations have the largest
effect on the system’s performance.
Some of the factors affected by temperature variations are:
•Length of capillary
•Quality of fill
•Static head effects
Length of Capillary As the length of capillary increases, the volume of fill fluid also
increases. Since the temperature effect will increase as the volume of
fill fluid increases, it is desirable to minimize the length of capillary.
During installation, the transmitter should be located as closely as
possible to the diaphragm seal. It is preferable to increase the length of
the loop wire rather than the length of capillary. The temperature effect
can also be minimized by maintaining a constant temperature along
the length of capillary. In addition to temperature effect, the length of
capillary also affects time response. As the length of capillary increases,
the time response increases.
Other parameters that must be considered when attempting to define
the performance of a remote seal system are vibration effects, remote
seal stability, and static head effects.
Quality of Fill The presence of air in the fill fluid will cause poor performance. If fill
fluid is lost due to damage to the remote seal system, it must be
replaced at Rosemount.
Static Head Effects If the diaphragm seal and transmitter are installed at different
elevations, a zero error occurs due to static head effects. Rezeroing the
transmitter after calibration eliminates this error. Static head effects
place limits on installation. Thus, elevation of the seal above the
transmitter is limited by the zero suppression capability of the
transmitter. If the seal is located below the transmitter, height
difference is limited not only by transmitter zero elevation capability,
but also by the requirement that liquid head cannot exceed atmospheric
pressure. Recommended maximum height difference to avoid this
limitation is 23 ft.
NOTE
For the Model 1152 Pressure Transmitter with remote diaphragm seal,
be sure to mount the transmitter at or below the lower tap to ensure
proper operation.

3Installation
Remote Seal Handling
Considerations When unpacking or handling a transmitter/seal system, do not lift the
seal or transmitter by gripping the capillaries.
Avoid sharply bending or crimping tubing. The minimum bending
radius of the capillary tubing is three inches (8 centimeters).
NOTE
Never attempt to disconnect the seals or capillaries from the
transmitter. Doing so will result in loss of fluid and will void the
product warranty.
The material of a diaphragm seal is designed to withstand pressure and
wear from process material, but outside of process connection
conditions, diaphragm seals are relatively delicate and should be
handled with care.
The protective cover should remain on the seal until the moment before
installation. Try to avoid touching the diaphragm with fingers or
objects and refrain from setting the diaphragm side of the seal down on
a hard surface. Even minor dents or scratches in the diaphragm
material may impair the performance of the transmitter/seal system.
When installing diaphragm seal systems, make sure the gasket is
aligned properly on the gasket sealing surface.
Most importantly, make sure the gasket does not press down upon the
diaphragm face. Anything pressing on the diaphragm will be read by
the transmitter as pressure. A misaligned gasket may cause a false
reading.
Remote Seal Installation
Considerations Due to infinite mounting configurations, mounting of the remote seal is
the responsibility of the customer. Refer to Rosemount Report
D8300151—Qualification Report for Water Filled Remote Seal System,
for mounting details during qualification testing.
The lower housing of the remote seal has a female thread connection for
attachment to a process pipe nipple. The diaphragm is welded to the
upper housing, allowing the diaphragm seal to be disassembled for
inspection without disturbing the fill fluid. The operating pressure of
the remote seal cannot exceed that of the transmitter; i.e., if it is used
with an 1152 DP, 1153 DB/DD/DF, or 1154 DP transmitter, the
maximum operating pressure is 2000 psi.
The remote seal is qualified for liquid service only. The process medium
should be free of solids, since these could clog the process pipe
connection or accumulate in the cavity on the process side of the
diaphragm. Care should be exercised in making sure that the process
fluid does not become overly viscous or freeze in the process pipe
connection or seal cavity.
Remote diaphragm seals have a ¼-in. NPT flushing connection (two
flushing connections provided with socket weld option) so that the
cavity under the diaphragm can be bled or flushed while the unit is in
service.

Model 1159 Remote Diaphragm Seals
3-2
Transmitters with remote diaphragm seals are frequently installed with
the transmitter and seal or seals at different elevations. In installations of
this type there will be a zero shift that must be corrected prior to
operation. This is most easily done by rezeroing the transmitter after
installation.
There are limits to the difference in elevations of seals and certain ranges
of transmitters. These limits are a function of the fill fluid and its specific
gravity. In no case should the difference in height between a transmitter
and seal or between two seals exceed the upper range limit of the
transmitter. Reference Table 3-1 below.
NOTE
For the Model 1152 Pressure Transmitter with remote diaphragm seal, be
sure to mount the transmitter at or below the lower tap to ensure proper
operation.
Changes in process and ambient temperatures can result in changes in
transmitter zero output. These effects can be minimized by heat tracing
the capillary to ensure a constant ambient temperature.
For operation at temperatures above 180 °F, apply a static pressure to the
remote seal to prevent the fill fluid from boiling. Reference steam tables
for appropriate pressures.
System Installation
Procedure Unbolt the seal upper and lower housing (they are factory assembled but
not torqued) and thread the lower housing to the hard piping separately.
When threading the lower housing to the process pipe, care should be
taken not to overtighten. The applied torque should comply to
ANSI B1.20.1 or applicable torque requirements for pipe connections. Bolt
the upper and lower housings together following the Metal Seal or Gasket
Installation procedure on page 3-3.
Whenever the upper and lower housings have been disassembled, you
must replace the metal seal or gasket.
Metal Seal or Gasket
Installation Procedure Follow the appropriate installation procedure depending on whether the
metal seal P/N 01159-0300-0002 or the gasket P/N 01159-0300-0001 is
being used.
