Ceramic process isolating diaphragms used for PMD70 and FMD76

The ceramic measuring cell is based on the principle of a plate capacitor with an electrode on (1) and a movable
electrode on the interior of the diaphragm (3). Standard silicone oil or mineral oil filling oils for this measuring
cell.
A differential pressure (p1 p2) causes a corresponding deflection of both diaphragms. Both capacitance values
are converted and are fed to the microprocessor of the transmitter as a digital signal.
Advantages:
• Self-monitoring for process isolating diaphragm break or oil loss (constant comparison of the measured
temperature with a temperature calculated from the capacitance values)
• Extremely high resistance to aggressive media
• Suitable for vacuums up to 1 mbarabs
• Metal-free versions available
• Second process barrier (Secondary Containment) for enhanced integrity

Metallic process isolating diaphragms used for PMD75, FMD77 and FMD78
The process isolating diaphragms (3/9) are deflected on both sides by the acting pressures. A filling oil (4/8)
transfers the pressure to a resistance circuit bridge (semi-conductor technology). The differential-pressure-
dependent change of the bridge output voltage is measured and further processed.
Advantages:
• Standard operating pressures: 160 bar and 420 bar
• High long-term stability
• Very high single-sided overload resistance
• Second process barrier (Secondary Containment) for enhanced integrity

Function Blocks

Block Content Number of Execution Functionality

Function Blocks time

Resource Block The Resource Block contains all the data that uni- enhanced
quely identifies the field device. It is an electronic
version of a nameplate of the device.

Analog Input The AI block takes the manufacturer's input data, 45 ms enhanced
Block 1 selected by channel number, and makes it avai-
Analog Input lable to other function blocks at its output.
Block 2 Enhancement: digital outputs for process alarms,
fail safe mode

Digital Input This block contains the discrete data of the diag- 40 ms standard
Block nose block (selectable via a channel number 0 to
16) and provides them for the blocks at the out-
put.

Digital Output This block converts the discrete input and thus 60 ms standard
Block initiates an action (selectable via a channel num-
ber) in the dp flow block or in the service block.
Channel 1 resets the counter for max. pressure
transgressions..

PID Block The PID block serves as proportional-integral-deri- 120 ms standard

vative controller and is used almost universally to
do closed-loop-control in the field including cas-
cade and feedforward. Input IN can be indicated
on the display. The selection is performed in the
display block
(DISPLAY_MAIN_LINE_CONTENT).
Arithmetic Block This block is designed to permit simple use of 50 ms standard
popular measurement math functions. The user
does not have to know how to write equations.
The math algorithm is selected by name, chosen
by the user for the function to be done.

Input Selector The input selector block provides selection of up 35 ms standard

Block to four inputs and generates an output based on
the configured action. This block normally recei-
ves its inputs from AI blocks. The block performs
maximum, minimum, middle, average and ‘first
good’ signal selection. INPUT IN1 to IN4 can be
indicated on the display. The selection is perfor-
med in the display block
(DISPLAY_MAIN_LINE_CONTENT).

Signal Characte- The signal characterizer block has two sections, 30 ms standard
rizer Block each with an output that is a non-linear function
of the respective input. The non-linear function is
determined by a single look-up table with 21 arbi-
trary x-y pairs.

Integrator Block The Integrator Function Block integrates a vari- 35 ms standard

able as a function of the time or accumulates the
counts from a Pulse Input block. The block may
be used as a totalizer that counts up until reset or
as a batch totalizer that has a setpoint, where the
integrated or accumulated value is compared to
pre-trip and trip settings, generating discrete
signals when these settings are reached.

Analog Alarm This block contains all process alarm conditions 35 ms standard
Block (working like a comparator) and represents them
at the output.

Operating conditions (Installation)

General installation • The position-dependent zero shift can be corrected directly at the device via operating key, for devices with
instructions external operation even in hazardous areas. Diaphragm seals also shift the zero point, depending on the
installation position ( ä 64 ff, "Installation instructions").
• The housing of the Deltabar S can be rotated up to 380°.  ä 26, section "Turn the housing".
• Endress+Hauser offers a mounting bracket for installing the device on pipes or walls.  ä 24, section "Wall-
and pipe-mounting".
• When measuring in media with solid proportions, such as dirty liquids, installing separators and drain valves
is useful for capturing and removing sediment.
• Using a three-valve or five-valve manifold allows for easy commissioning, installation and maintenance
without interrupting the process.
• General recommendations for the impulse piping can be found in DIN 19210 "Methods for measurement of
fluid flow; differential piping for flow measurement devices" or the corresponding national or international
standards.
• Install the impulse piping with a continuous gradient of at least 10%.
• When routing the impulse piping outdoors, ensure that sufficient anti-freeze protection is used, e.g. by using
pipe heat tracing.
• For FMD77 and FMD78: See page 64 ff, "Installation instructions, Diaphragm seal systems" section.

Measuring arrangement Flow measurement

• The PMD70 and PMD75 are best suited to flow measurement.
• Measuring arrangement for gases: Mount device above the measuring point.
• Measuring arrangement for liquids and vapours: Mount device below tapping point.
• For flow measurement in vapours, mount the condensate traps at the same level as the same the tapping
point and at the same distance from Deltabar S.

Level measurement
• PMD70, PMD75, FMD76 and FMD77 are best suited to level measurement in open tanks. All Deltabar S
devices are suitable for level measurement in closed tanks.

Measuring arrangement level measurement in open tanks

• PMD70, PMD75: Mount device below the lower measuring connection. The negative side is open to
atmosphere pressure.
• FMD76, FMD77: Mount device direct on the tank. The negative side is open to atmosphere pressure.

Measuring arrangement level measurement in closed tanks and closed tanks with superimposed vapour
• PMD70, PMD75: Mount device below the lower measuring connection. Always connect the negative side
above the maximum level.
• FMD76, FMD77: Mount device direct on the tank. Always connect the negative side above the maximum
level.
• In the case of level measurement in closed tanks with superimposed vapour, a condensate trap ensures
pressure which remains constant on the minus side.

Pressure measurement
• The PMD70 and PMD75 are best suited to differential pressure measurement.
• Measuring arrangement for gases: Mount device above the measuring point.
• Measuring arrangement for liquids and steams: Mount device below tapping point.
• For differential pressure measurement in vapour, mount the condensate traps at the same level as the same
the tapping point and at the same distance from Deltabar S.

Pressure specifications • The maximum pressure for the measuring device is dependent on the lowest-rated element with regard to
pressure, see the following sections for this:
–  ä 8 ff, section "Measuring range"
– chapter "Mechanical construction".
The MWP (maximum working pressure) is specified on the nameplate. This value refers to a reference
temperature of 20°C (68°F) or 100°F for ANSI flanges and may be applied to the device for an unlimited
time. Observe pressure-temperature dependency.
• The pressure values permitted at higher temperatures can be found in the following standards:
– EN 1092-1: 2001 Tab. 18 1
– ASME B 16.5a – 1998 Tab. 2-2.2 F316
– ASME B 16.5a – 1998 Tab. 2.3.8 N10276
– JIS B 2220
• For PMD70 and PMD75, the MWP applies for the temperature ranges specified in the "Ambient temperature
range" ( ä 27) and "Process temperature limits" ( ä 28) sections.
• The test pressure corresponds to the over pressure limit of the measuring instrument (Over pressure limits
OPL = 1.5 x MWP) and may fit only temporally limited, so that no permanent damage develops.
• The Pressure Equipment Directive (EC Directive 97/23/EC) uses the abbreviation "PS". The abbreviation
"PS" corresponds to the MWP (maximum working pressure) of the measuring device.
• In the case of sensor range and process connections where the OPL (Over Pressure Limit) of the pressure
connection is smaller than the nominal value of the sensor, the device is set at the factory, at the very
maximum, to the OPL value of the process connection. If you want to use the entire sensor range, select a
process connection with a higher OPL value (1.5 x PN; PN = MWP).
• In oxygen applications, the values for "pmax and Tmax for oxygen applications" as per  ä 26, "Oxygen
applications" may not be exceeded.

1) With regard to their stability-temperature property, the materials 1.4435 and 1.4404 are grouped together under 13EO
in EN 1092-1 Tab. 18. The chemical composition of the two materials can be identical.

with metallic process isolating • Specifications for the "TK Process" are listed in the following tables. These are typically values. These
diaphragm temperature coefficients apply to silicone oil and the process isolating diaphragm material AISI 316L/
1.4435. For other filling oils, this temperature coefficient must be multiplied by the TK correction factor of
the corresponding filling oil. For the TK correction factors, see also  ä 59 ff, section "Diaphragm seal filling
oils".
• The temperature coefficient "TK Ambient" is listed in relation to the capillary length on  ä 60 in the
"Influence of the temperature on the zero point" section.
• The weights of the diaphragm seals are given in the tables. See  ä 33 for the weight of the transmitter
and  ä 51 for the weight of the housing.
• The following drawings are drawings that illustrate how the system works in principle. In other words, the
dimensions of a diaphragm seal supplied can deviate from the dimensions given in this document.

Planning instructions, diaphragm seal systems

With the Endress Hauser selection tool "Applicator" you will find the optimum diaphragm seal for your
application. Online on "www.endress.com/applicator" or offline (on CD)
For further information please contact your local Endress+Hauser Sales Center.

Applications Diaphragm seal systems should be used if the process media and the device should be separated. Diaphragm
seal systems offer clear advantages in the following instances:
• In the case of high process temperatures ( ä 28, section "Process temperature limits".)
• In the case of process media that crystallise
• In the case of corrosive or highly various process media or process media with solids content
• In the case of heterogeneous and fibrous process media
• If good and rapid measuring point cleaning is necessary
• If the measuring point is exposed to vibrations
• For mounting locations that are difficult to access

Design and operation mode Diaphragm seals are separating equipment between the measuring system and the process medium.
A diaphragm seal system consists of:
• A diaphragm seal in a one-sided system, e.g. FMD77 or two diaphragm seals, in a two-sided system, e.g.
FMD78
• One capillary tube or two capillary tubes
• Fill fluid and
• A differential pressure transmitter.
The process pressure acts via the process isolating diaphragm of the diaphragm seal on the liquid-filled system,
which transfers the process pressure via the capillary tube onto the sensor of the differential pressure
transmitter.
Endress+Hauser delivers all diaphragm seal systems as welded versions. The system is hermetically sealed,
which ensures the highest reliability.
Note!
The correlations between the individual diaphragm seal components are presented in the following section.
For further information and comprehensive diaphragm seal system designs, please contact your local
Endress+Hauser Sales Center.

Diaphragm seal
The diaphragm seal determines the application range of the system by
• the process isolating diaphragm diameter
• the process isolating diaphragm stiffness and material
• the design (oil volume).

Diaphragm diameter
The larger the diaphragm diameter (less stiffness), the smaller the temperature effect on the measurement
result.
Note: To keep the temperature effect in practice-oriented limits, you should select diaphragm seals with a
nominal diameter of DN 80, in as far as the process connection allows for it.

Diaphragm stiffness
The stiffness is dependent on the process isolating diaphragm diameter, the material, any available coating and
on the diaphragm thickness and shape. The diaphragm thickness and the shape are defined constructively. The
stiffness of a process isolating diaphragm of the diaphragm seal influences the temperature operating range and
the measuring error caused by temperature effects.

Capillary
Diaphragm seals are used with the following capillary internal diameters as standard:
• DN 50: 1 mm
• > DN 50: 2 mm
The capillary tube influences the TK zero point, the ambient temperature operating range and the response time
of a diaphragm seal system as a result of its length and internal diameter.
 ä 60 ff, sections "Influence of the temperature on the zero point", "Ambient temperature range" and
"Response time".

58 Endress+Hauser
Deltabar S

Observe the installation instructions regarding capillary tubes. See  ä 64 ff, section "Installation
instructions".

Filling oil
When selecting the filling oil, fluid and ambient temperature as well as the operating pressure are of crucial
importance. Observe the temperatures and pressures during commissioning and cleaning. A further selection
criterion is the compatibility of the filling oil with the requirements of the process medium. For this reason,
only filling oils that are harmless to health are used in the food industry, such as vegetable oil or silicone oil. 
See also the following section "Diaphragm seal filling oils".
The filling oil used influences the TK zero point and the temperature operating range of a diaphragm seal system
and the response time.  ä 60 ff, sections "Influence of the temperature on the zero point" and "Response
time".

Differential pressure transmitter

The differential pressure transmitter influences the temperature operating range, the TK zero point and the
response time as a result of the volume of its side flange and as a result of its volume change. The volume
change is the volume that has to be shifted to pass through the complete measuring range.
Differential pressure transmitters from Endress+Hauser are optimised with regard to minimum volume change
and side flange.

Influence of the temperature A temperature change results in a volume change of the filling oil. The volume change is dependent on the
on the zero point coefficient of thermal expansion of the filling oil and on the volume of the filling oil at calibration temperature
(constant in the range: +21 to +33°C (+69.8 to 91.4°F)).  ä 59, section "Diaphragm seal filling oils".
For example, the filling oil expands in the event of a temperature increase. The additional volume presses
against the process isolating diaphragm of the diaphragm seal. The stiffer a diaphragm is, the greater its return
force, which counteracts a volume change and acts on the measuring cell together with the operating pressure,
thus shifting the zero point. For the "TK Process", see  ä 43 ff, section "Process connections FMD78".
The following diagrams display the temperature coefficient "TK Ambient" dependent on the capillary length.
The following application is displayed: capillary temperature and transmitter temperature (ambient
temperature) change, the process temperature corresponds to the calibration temperature.
The temperature coefficients obtained from the diagrams apply to silicone oil and the process isolating
diaphragm material AISI 316L/1.4435. For other filling oils, these temperature coefficients must be multiplied
by the TK correction factor of the corresponding filling oil. For the TK correction factors, see  ä 59, section
"Diaphragm seal filling oils".

– Capillary length: 5 m
– Ambient temperature, capillary/transmitter: 45°C
– Filling oil: silicone oil
1. Select characteristic curve type for the diaphragm seal versions "B5" in accordance with the following
table.
Result: characteristic curve type 2
2. Obtain value for TK Ambient from the diagram.
Result: 1.4 mbar/10 K
3. TAmbient – TCalibration = 45°C – 25°C = 20°C 1.4 mbar/10 K x 20 K = 2.8 mbar
Result: In this application, the zero point is shifted by 2.8 mbar.
Note!
• The influence of temperature on the zero point can be corrected with position calibration.
• The temperature influence can be minimised by using a filling oil with a smaller coefficient of thermal
expansion, shorter capillaries, diaphragm seals with larger diaphragm diameter or by using a smaller capillary
internal diameter.

Ambient temperature range The operating temperature range of a diaphragm seal system depends on Fill fluid, "Capillary length and
internal diameter, Process temperature and Diaphragm seal oil volume.
The range of application can be extended by using a fill fluid with a smaller expansion coefficient and a shorter
capillary. The permitted operating temperature ranges in relation to the capillary length can be calculated
online at "Applicator Sizing Diaphragm Seal":
http://www.endress.com/applicator -> Applicator Sizing Diaphragm Seal -> Horncurve

P01-xxxxxxxx-20-xx-xx-en-001

Note!
• Endress+Hauser recommends you use a low temperature oil for applications that require short response
times or are close to the lower temperature limit (see "diaphragm seal fill fluid").
• Please contact your Endress+Hauser sales office for further information, comprehensive diaphragm seal
system designs and measuring technology solutions that are close to the application limits.

Response time The viscosity of the filling oil, the capillary length and the capillary internal diameter influence the frictional
resistance. The greater the frictional resistance, the longer the response time.
Furthermore, the volume change of the measuring cell influences the response time. The lower the
volume change of the measuring cell is, the less filling oil has to be shifted in the diaphragm seal system.
The following diagram shows typical response times (T90) for the various filling oils dependent on the
measuring cell and the capillary internal diameter. The values given are in seconds per metre of capillary length
and must be multiplied by the actual length of the capillary. The response time of the transmitter must also be
taken into consideration.

transmitters out of process.
For further information please contact your local Endress+Hauser Sales Center.
• The diaphragm seal together with the transmitter form a closed, calibrated system, which is filled through
ports in the diaphragm seal and in the measuring system of the transmitter. These ports are sealed and must
not be opened.
• In the case of devices with diaphragm seals and capillaries, the zero point shift caused by the hydrostatic
pressure of the filling liquid column in the capillaries must be taken into account when selecting the
measuring cell. If a measuring cell with a small measuring range is selected, the sensor nominal range can
be overdriven as a result of position adjustment.  See the following diagram and the following example.
• For devices with capillary a suitable fastening device (mounting bracket) is recommended.
• When using a mounting bracket, sufficient strain relief must be allowed for in order to prevent the capillary
bending down (bending radius 100 mm).
• The temperature and length of both capillaries should be the same when using two-sided diaphragm seal
systems.

Selecting the measuring cell (observe the hydrostatic pressure of the filling fluid column in the capillaries!)

Result:
If the tank were full, a differential pressure of –51.80 mbar would be present at the differential pressure transmitter. When
the tank is empty, a differential pressure of –149.90 mbar is present. Therefore, a 500 mbar measuring cell is required for
this application.

Installation instructions
In order to obtain more precise measurement results and to avoid a defect in the device, mount the capillaries
as follows:
• vibration-free (in order to avoid additional pressure fluctuations)
• not in the vicinity of heating or cooling lines
• insulate if the ambient temperature is below ore above the reference temperature
• with a bending radius of 100 mm.

Vacuum applications
For applications under vacuum, Endress+Hauser recommends mounting the pressure transmitter underneath
the lower diaphragm seal. A vacuum load of the diaphragm seal caused by the presence of filling oil in the
capillaries is hereby prevented.
When the pressure transmitter is mounted above the lower diaphragm seal, the maximum height difference
H1 in accordance with the following illustration on the left must not be exceeded. The maximum height
difference is dependent on the density of the filling oil and the smallest ever pressure that is permitted to occur
at the diaphragm seal on the positive side (empty tank), see the following illustration, on the right.
