Measuring principle
Ceramic measuring diaphragms used for PMD 70 and FMD 76
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 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 0.02 psiabs (1 mbarabs)• Metal-free versions available
• Secondary process barrier for enhanced mechanical integrity
Metallic measuring diaphragms used for PMD 75, FMD 77 and FMD 78
The separating 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 change due to differential pressure
of the bridge output voltage is measured and further processed.
Advantages:
• Standard operating pressures: 2320 psi and 6100 psi (160 bar and 420 bar)
• High long-term stability
• Very high single-sided overload resistance
• Secondary process barrier for enhanced mechanical integrity

Operating conditions (installation)
General installation instructions • For FMD 77 and FMD 78: See page 50 ff, "Installation instructions, Diaphragm seal systems" section.
• The position-dependent zero shift can be corrected directly at the device via operating keys, even in
hazardous areas. Diaphragm seals also shift the zero point, depending on the installation position (→ See also
page 50 ff, "Installation instructions, Diaphragm seal systems").
• The housing of the Deltabar S can be rotated up to 380°. → See also page 22, section "Rotating the housing".
• Endress+Hauser offers a mounting bracket for installing on pipes or walls. → See also page 22, 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.
Measuring arrangement Flow measurement
• The PMD 70 and PMD 75 are best suited to flow measurement.
• Measuring arrangement for gases: Mount device above the measuring point.
• Measuring arrangement for liquids and steam: Mount device below tapping point.
• For flow measurement in steam, mount the condensate traps at the same level as the tapping point and at
the same distance from Deltabar S.
Level measurement
• PMD 70, PMD 75, FMD 76 and FMD 77 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
• PMD 70, PMD 75: Mount device below the lower measuring connection. The negative side is open to
atmosphere pressure.
• FMD 76, FMD 77: Mount device directly on the tank or with shut-off valve. The negative side is open to
atmospheric pressure.
Measuring arrangement level measurement in closed tanks and closed tanks with static pressure
• PMD 70, PMD 75: Mount device below the lower measuring connection. Always connect the negative side
above the maximum level.
• FMD 76, FMD 77: Mount device directy on the tank. Always connect the negative side above the maximum
level.
• In the case of level measurement in closed tanks with static pressure, a condensate trap ensures pressure
which remains constant on the minus side.
Pressure measurement
• The PMD 70 and PMD 75 are best suited to differential pressure measurement.
• Measuring arrangement for gases: Mount device above the measuring point.
• Measuring arrangement for liquids and steam: Mount device below tapping point.
• For differential pressure measurement in steam, mount the condensate traps at the same level as the tapping
point and at the same distance from Deltabar S.

Oxygen applications Oxygen and other gases can react explosively to oils, grease and plastics, such that, among other things, the
following precautions must be taken:
– All components of the system, such as measuring devices, must be cleaned in accordance with standard
requirements (BAM, DIN 19247, CGA-4.1-1996, AGA G93-96).
– Dependent on the materials used, maximum temperature and a maximum pressure must not be exceeded.
The devices suitable for oxygen applications are listed in the following table with the specifications Tmax and
pmax.
Ultra pure gas applications Endress+Hauser also offers degreased devices for special applications, such as ultra pure gas.
No special restrictions regarding the process conditions apply to these devices.
→ See also page 53 ff, PMD 70 and PMD 75: feature 80 "Gasket material", FMD 76 and FMD 77: feature 70
"Process connection low-pressure side, material, seal".
Diaphragms for materials with
hydrogen build-up (Rhodium-
Gold coating)
When materials are used in which hydrogen build-up occurs, hydrogen atoms can diffuse through the metals
of the sensor. This can lead to corrupt measurement results.
Endress+Hauser offers diaphragms with Rhodium-Gold coating for this application.

Planning instructions, diaphragm seal systems
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 (→ See also page 24, section "Process temperature limits".)
• In the case of process media that crystallize
• In the case of corrosive process media or process media with solids content
• In the case of heterogeneous and fibrous process media
• If measuring point cleaning is necessary
• The measuring point is exposed to vibration.
• Installation sites that are difficult to access (e.g. better view of display).
Design and operation mode Diaphragm seals separate the measuring system and the process medium.
A diaphragm seal system consists of:
• A diaphragm seal in a one-sided system, e.g. FMD 77 or two diaphragm seals, in a two-sided system, e.g.
FMD 78
• Capillary tube
• Fill fluid and
• A differential pressure transmitter.
The process pressure acts via the diaphragm seal membrane 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 Endress+Hauser
Sales.
Diaphragm seal
The diaphragm seal determines the application range of the system by
• the diaphragm diameter
• the diaphragm: stiffness and materials of construction
• the design (oil volume).
Diaphragm diameter
The larger the diaphragm diameter (less stiffness), the smaller the temperature effect on the measurement
result.
Note: When feasible, select diaphragm seals with a nominal diameter of ≥ 3" (DN 80), to reduce temperature
effects within acceptable limits.
Diaphragm stiffness
The stiffness is dependent on the diaphragm diameter, the material, any available coating and on the diaphragm
thickness and shape. The diaphragm thickness and the shape are defined by the limits of the process connection
construction. The stiffness of a diaphragm seal membrane 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:
• ≤ 2" (DN 50): 0.04" (1 mm)
• > 2" (DN 50): 0.08" (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.
→ See also page 47 ff, sections "Influence of the temperature on the zero point for diaphragm seal systems", "Ambient temperature range" and "Response time".
→ Observe the installation instructions regarding capillary tubes. See page 50 ff, section "Installation instruc-tions".

46 Endress+Hauser
Filling oil
When selecting the filling oil, fluid and ambient temperature as well as the operating pressure are of crucial
importance. Pay attention to 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 non-toxic 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. → See also page 47 ff, sections "Influence of the temperature on the zero point for diaphragm seal systems" 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 optimized with regard to minimum volume change
and side flange.

Influence of the temperature on
the zero point for diaphragm
seal systems
A temperature change results in a volume change of the filling oil. The volume change is dependent on the
coefficient of thermal expansion of the filling oil and on the volume of the filling oil at calibration temperature
(+77°F/+25°C , range: +69.8 to 91.4°F/+21 to +33°C). → See also page 46, section "Diaphragm seal filling
oils".
For example, the filling oil expands in the event of a temperature increase. The additional volume presses
against the diaphragm seal membrane. 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 page 37 ff, section "Process connections FMD 78".
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 membrane material AISI
316L. 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 page 46, section "Diaphragm seal filling oils".

Example for:
– Diaphragm seal versions "B5, EN/DIN Flange DN 80 PN 10-40 B1, AISI 316L"
– Capillary length: 16 ft (5 m)
– Ambient temperature, capillary/transmitter: 113°F (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 • 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.

Ambient temperature range The filling oil, capillary length, capillary internal diameter and the diaphragm diameter of the diaphragm seal
have an influence on the ambient temperature operating range of a diaphragm seal system.
Note!
For further information and comprehensive diaphragm seal system designs, please see your local
Endress+Hauser Sales Center.
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 rise time of the transmitter must also be taken
into consideration.

Installation instructions Instructions for diaphragm seal systems
• 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.
• When selecting the measuring cell, observe the zero shift resulting from the hydrostatic pressure of the filling
fluid columns in the capillaries. (→ See the following illustration).
• When using a mounting bracket, sufficient strain relief must be allowed in order to prevent the capillary from
exceeding a bending radius ≥ 4" / 100 mm.
• The temperature and length of both capillaries should be the same when using two-sided diaphragm seal
systems.

Installation instructions
In order to obtain more precise measurement results and to avoid a device failure, mount the capillaries as
follows:
• vibration-free (in order to avoid additional pressure fluctuations)
• not in the vicinity of heating or cooling lines
• insulate at colder or warmer ambient temperatures
• with a bending radius of ≥ 4" (100 mm).
Vacuum applications
For applications under vacuum, Endress+Hauser recommends mounting the pressure transmitter below 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 minimum expected pressure that is permitted
to occur at the diaphragm seal on the positive side (empty tank), see the following illustration, on the right.
Pressure on the negative side of the differential pressure transmitter (p–) when the tank is empty (min. level)
Pressure on the positive side of the differential pressure transmitter (P+) when the tank is empty (min. level)
Differential pressure at the transmitter (∆pTransmitter) when the tank is empty
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.
