Item Term/abbreviation Explanation

1 OPL The OPL (over pressure limit = sensor overload limit) for the measuring device depends on the lowest-rated element,

with regard to pressure, of the selected components, i.e. the process connection has to be taken into consideration in addition to the measuring cell. Also observe pressure-temperature dependency. For the relevant standards and additional information, see the "Pressure specifications"→  47 section. The OPL may only be applied for a limited period of time.

2 MWP The MWP (maximum working pressure) for the sensors depends on the lowest-rated element, with regard to

pressure, of the selected components, i.e. the process connection has to be taken into consideration in addition to the measuring cell. Also observe pressure-temperature dependency. For the relevant standards and additional information, see the "Pressure specifications"→  47 section. The MWP may be applied at the device for an unlimited period. The MWP can also be found on the nameplate.

Wide range of diaphragm seals

Measuring principle Metal process isolating diaphragm

1 Measuring element 2 Middle diaphragm 3 Filling oil 4 Process isolating diaphragm

The process isolating diaphragms are deflected on both sides by the acting pressures. A filling oil transfers the pressure to a resistance bridge (semiconductor technology). The change in the bridge output voltage, which depends on the differential pressure, is measured and processed

Advantages:

• Standard system pressures: 160 bar (2 400 psi) up to 420 bar (6 300 psi)

• High long-term stability

• Very high single-sided overload resistance

This block contains the discrete data of the Diagnose Block (selectable via a channel number 0 to 16) and provides them for other blocks at the output.

This block converts the discrete input and thus initiates an action (selectable via a channel number) in the DP Flow Block or in the Service Block. Channel 1 resets the counter for max. pressure transgressions.

can be used universally for closed-loop-control in the field. It enables cascade mode and feedforward control. Input IN can be indicated on the display. The selection is performed in the Display Block (DISPLAY_MAIN_LINE_CONTENT).

This block is designed to permit simple use of 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 performed.

The Input Selector Block facilitates the selection of up to four inputs and generates an output based on the configured action. This block normally receives its inputs from AI Blocks. The block performs maximum, minimum, average and ‘first good’ signal selection. Inputs IN1 to IN4 can be indicated on the display. The selection is performed in the Display Block (DISPLAY_MAIN_LINE_CONTENT).

The Signal Characterizer Block has two sections, each with an output that is a non-linear function of the respective input. The non-linear function is generated by a single look-up table with 21 arbitrary x-y pairs.

Detailed Performance Explanation and Calculation

To calculate the total performance outside the temperature range of –3 to +53 °C (+27 to +127 °F) or for a membrane material other than 1.4435/316L or Alloy C 276, please refer to the following sections: "Ambient temperature effect", "Static pressure effect" and "Calculating the total performance"

Ambient temperature effect [E2]

• E2 = (E2M · CF1 · CF2) + E2E + E2

• E2M = Main temperature error

• CF1 = Temperature range correction factor

• CF2 = Membrane material correction factor (thermal)

• E2E = Electronics error for analog output

• E2LT = low temperature error

E2M - Main temperature error

The output changes due to the effect of ambient temperature [IEC 61298-3] with respect to reference temperature [DIN 16086]. The values specify the maximum error due to min./max. ambient or process temperature conditions.

Installation

Deltabar S PMD75, FMD77, FMD78

General installation instructions

Measuring arrangement Flow measurement

• A position-dependent zero point shift can be corrected directly at the device via operating keys, and also in hazardous areas in the case of devices with external operation. Diaphragm seals also shift the zero point, depending on the installation position →  98.

• The device housing can be rotated up to 380° .

• Endress+Hauser offers a mounting bracket for installing the device on pipes or walls →  39.

• Use flushing rings for flange and cell diaphragm seals if buildup or clogging can be expected at the diaphragm seal connection. The flushing ring can be fitted between the process connection and diaphragm seal. Material buildup in front of the process isolating diaphragm can be flushed away, and the pressure chamber vented, via the two lateral flushing holes.

• When measuring in media containing solids, such as dirty liquids, installing separators and drain valves is useful for capturing and removing sediment.

• Using a valve manifold allows for easy commissioning, installation and maintenance without interrupting the process.

• General recommendations for the pressure 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 pressure piping with a continuous gradient of at least 10%.

• When routing the pressure piping outdoors, ensure sufficient anti-freeze protection, e.g. by using pipe heat tracing.

• Point the cable and connector downwards where possible to prevent moisture from entering (e.g. rain or condensation water).

• The PMD75 is best suited to flow measurement.

• Measuring arrangement for gases: Mount device above the measuring point.

• Measuring arrangement for liquids and vapors: Mount device below the measuring point.

• For flow measurement in vapors, mount the condensate traps at the same level as the tapping point and at the same distance from the Deltabar S.

Measuring arrangement for devices with diaphragm seals – FMD77 and FMD78

Level measurement

The PMD75 and FMD77 are best suited to level measurement in open containers. All Deltabar S devices are suitable for level measurement in closed vessels.

Measuring arrangement for level measurement in open containers

• PMD75: Mount device below the lower measuring connection. The negative side is open to atmospheric pressure.

• FMD77: Mount device directly on the vessel. The negative side is open to atmospheric pressure.

Measuring arrangement for level measurement in closed containers and closed containers with superimposed vapor

• PMD75: Mount device below the lower measuring connection. Always connect the negative side above the maximum level via pressure piping.

• FMD77: Mount device directly on the vessel. Always connect the negative side above the maximum level via pressure piping.

• In the case of level measurement in closed vessels with superimposed vapor, a condensate trap ensures the pressure remains constant on the minus side.

Pressure measurement

• The PMD75 and FMD78 are best suited to differential pressure measurement.

• Measuring arrangement for gases: Mount device above the measuring point.

• Measuring arrangement for liquids and vapors: Mount device below the measuring point.

• For differential pressure measurement in vapors, mount the condensate traps at the same level as the tapping point and at the same distance from the Deltabar S.

Orientation

The orientation may cause a zero point shift, see →  36.

This position-dependent zero point shift can be corrected directly at the device via the operating key, and also in hazardous areas in the case of devices with external operation (position adjustment).

FMD77: Selecting the process connection and capillary line

The device can be fitted with different process connections on the high-pressure side (HP) and on the low-pressure side (LP).

The FMD77 can also be fitted with capillary lines on the low-pressure side (LP).

When using diaphragm seal systems with a capillary, sufficient strain relief must be provided to prevent the capillary from bending (capillary bending radius ≥ 100 mm (3.94 in)).

Example:

• Process connection on high-pressure side = DN80 flange

• Process connection on low-pressure side = DN50 flange

Your benefits:

• Thanks to the variety of order options, the devices can be optimally adapted to the given installation situation

• Reduced costs due to optimum system design

• Easier installation due to adjusted length of capillary line

• Easier adaptation to existing installation situations

Ordering information:

• Process connections are indicated in the relevant section by HP (high-pressure side) and LP (lowpressure side)

• Order details for capillary lengths →  86

A0027889

Due to the use of different process connections and capillary lines, it is essential that the device be designed/ordered using the "Applicator Sizing Diaphragm Seal" selection tool, which is available free of charge.

The device can be fitted with different process connections on the high-pressure side (HP) and on the low-pressure side (LP).

The FMD78 can also be fitted with different capillary lengths on the high-pressure side (HP) and on the low-pressure side (LP).

When using diaphragm seal systems with a capillary, sufficient strain relief must be provided to prevent the capillary from bending (capillary bending radius ≥ 100 mm (3.94 in)).

Example:

• Process connection on high-pressure side = DN80 flange

• Process connection on low-pressure side = DN50 flange

• Capillary length on high-pressure side = 2 m (6.6 ft)

• Capillary length on low-pressure side = 5 m (16 ft)

Your benefits:

• Thanks to the variety of order options, the devices can be optimally adapted to the given installation situation

• Reduced costs due to optimum system design

Process connections

• "Clamp connections" and "Hygienic process connections": AISI 316L (DIN/EN material number

1.4435)

• Endress+Hauser supplies DIN/ EN process connections with threaded connections made of stainless steel as per AISI 316L (DIN/EN material number 1.4404 or 14435). With regard to their stability-temperature property, the materials 1.4404 and 1.4435 are grouped together under 13E0 in EN 1092-1: 2001 Tab. 18. The chemical composition of the two materials can be identical.

• Some process connections are also available in alloy C276 (DIN/EN material number 2.4819). For this purpose see the information in the "Mechanical construction" section.

• Side flanges: 316L, C 22.8 with zinc plating or alloy C 276. The C22.8 side flanges are coated with anti-corrosion protection (zinc, chrome). To prevent the formation of hydrogen and thereby diffusion through the membrane, Endress+Hauser recommends the use of 316L side flanges for applications involving water. Hydrogen diffusion through the membrane leads to measurement errors, or in extreme cases to a device failure.

Planning instructions, diaphragm seal systems

NOTICE

Incorrect sizing/ordering of diaphragm seal systems

The performance and the permitted range of application of a diaphragm seal system depend on the process isolating diaphragm used, the filling oil, the coupling, the unit design and on the process and ambient conditions present in the individual application.

To help you select the right diaphragm seal systems for your particular applications, Endress

‣

+Hauser provides its customers with the "Applicator Sizing Diaphragm Seal" selection tool, which is available free of charge at "www.endress.com/applicator" or as a download.

Applications

A0034616

For more detailed information or the layout of the optimum diaphragm seal solution for your application, please contact your local Endress+Hauser Sales Center.

Diaphragm seal systems should be used if the process and the device should be separated. Diaphragm seal systems offer clear advantages in the following instances:

• In the case of extreme process temperatures

• For aggressive media

• In the case of process media that crystallize

• 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 extreme measuring point cleaning is necessary, or for very humid mounting locations

• If the measuring point is exposed to severe vibrations

• For mounting locations that are difficult to access

94 Endress+Hauser

Page 95

Deltabar S PMD75, FMD77, FMD78

Design and operation mode

Diaphragm seals are separating equipment between the measuring system and the process.

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

• A differential pressure transmitter

The process pressure acts via the process isolating diaphragm of the diaphragm seal on the liquidfilled 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.

The diaphragm seal determines the application range of the system by:

• The diameter of the process isolating diaphragm

• The stiffness and material of the process isolating diaphragm

• The design (oil volume)

Diameter of the process isolating diaphragm

The greater the diameter of the process isolating diaphragm (less stiff), the smaller the temperature effect on the measurement result.

Stiffness of the process isolating diaphragm

The stiffness depends on the diameter of the process isolating diaphragm, the material, any existing coating and the thickness and shape of the process isolating diaphragm. The thickness of the process isolating diaphragm and the shape are determined by the design. The stiffness of a process isolating diaphragm of a diaphragm seal influences the temperature operating range and the measuring error caused by temperature effects.

The Endress+Hauser TempC membrane: Highest accuracy and process safety when measuring pressure and differential pressure using diaphragm seals

To measure even more precisely in such applications and to increase process safety, Endress+Hauser has developed the TempC membrane based on a completely revolutionary technology. This membrane guarantees the highest level of accuracy and process safety in diaphragm seal applications.

• The very low temperature effect minimizes the influence of fluctuations of both process and ambient temperatures, thus guaranteeing accurate and stable measurements. Measurement inaccuracies caused by temperature are reduced to a minimum.

• The TempC membrane can be used at temperatures between –70 °C (–94 °F) and +400 °C (+752 °F). This guarantees maximum process safety even for very long sterilization and cleaning cycles (SIP/CIP) in tanks and pipes at high temperatures.

• Thanks to the TempC membrane, smaller dimension process connections are possible. With a smaller process connection, the new membrane measures at least as accurately as a conventional membrane with a larger diameter.

• Due to the geometry of the membrane, an overshoot occurs initially immediately following a temperature shock. This results in a transient response, the duration and deviation of which are significantly less compared to traditional membrane types. In the case of batch processes, these shorter recovery times mean a far higher level of availability of the production facilities. For TempC membranes, the effect of the overshoot on the output signal can be reduced by adjusting the damping.

Ordering information:

See the Product Configurator for the individual process connection and the choice of process isolating diaphragm.

Selection in the Applicator:

Under "Transmitter data" in the "Membrane material" field.

Capillary

Diaphragm seals are used with the following capillary internal diameters as standard:

• ≤ DN 50: 1 mm (0.04 in)

• > DN 50: 2 mm (0.08 in)

Endress+Hauser 95

Page 96

Deltabar S PMD75, FMD77, FMD78

The capillary tube influences the thermal change, the ambient temperature operating range and the response time of a diaphragm seal system as a result of its length and internal diameter.

Filling oil

When selecting the filling oil, the media 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 media. For this reason, only filling oils that are harmless to health may be used in the food industry, such as vegetable oil or silicone oil (see also the following section on "diaphragm seal filling oils").

The filling oil used influences the thermal change, the temperature operating range of a diaphragm seal system and the response time. A temperature change results in a volume change of the filling oil. The volume change is dependent on the expansion coefficient and on the volume of the filling oil at calibration temperature (constant in range: +21 to +33 °C (+70 to +91 °F)). The application range can be extended by a filling oil with a lower expansion coefficient and a shorter capillary.

For example, the filling oil expands in the event of a temperature increase. The additional volume presses against the process isolating diaphragm of a diaphragm seal. The stiffer a process isolating 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.

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 the minimum volume change and side flange.

Operating temperature range

The operating temperature range of a diaphragm seal system depends on the fill fluid, capillary length and internal diameter, process temperature and oil volume of the diaphragm seal.

The application range can be extended by using a filling oil with a smaller expansion coefficient and a shorter capillary.

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, the less filling oil has to be shifted in the diaphragm seal system.

To help you select the right diaphragm seal systems for your particular applications, Endress+Hauser provides its customers with the "Applicator Sizing Diaphragm Seal" selection tool, which is available free of charge at "www.endress.com/applicator" or can be ordered on a DVD.

Information on cleaning

Endress+Hauser provides flushing rings as an accessory to enable cleaning of the process isolating diaphragm without removing the transmitter from the process.

For further information please contact your local Endress+Hauser Sales Center.

We recommend you perform CIP (cleaning in place (hot water)) before SIP (sterilization in place (steam)) for pipe diaphragm seals. A frequent use of sterilization in place (SIP) will increase the stress on the process isolating diaphragm. Under unfavorable circumstances in the long term view we cannot exclude that a frequent temperature change could lead to a material fatigue of the process isolating diaphragm and possibly to a leakage.

Installation instructions 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.

• 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 figure and the example below).

• For devices with a capillary a suitable fastening device (mounting bracket) is recommended.

• When mounting, sufficient strain relief must be provided for the capillary line to prevent the capillary from bending (capillary bending radius ≥ 100 mm (3.94 in)

• For more detailed installation instructions, Endress+Hauser provides its customers with the free "Applicator Sizing Diaphragm Seal" selection tool, which is available online at "www.endress.com/ applicator" or as a download.

Result:

When the vessel is full, a differential pressure of –51.80 mbar (–0.762 psi) is present at the differential pressure transmitter. When the vessel is empty, a differential pressure of –149.90 mbar (–2.2485 psi) is present. A 500 mbar (7.5 psi)measuring cell is therefore necessary for this application.

Capillary

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 or above the reference temperature

• with a bending radius ≥ 100 mm (3.94 in)

• When using diaphragm seal systems with a capillary, sufficient strain relief must be provided to prevent the capillary from bending (capillary bending radius ≥ 100 mm (3.94 in)).

Heat insulation – FMD77

The FMD77 must only be insulated up to a certain height. The maximum permitted insulation height applies to an insulation material with a heat conductivity ≤ 0.04 W/(m x K) and to the maximum permitted ambient and process temperature. The data were determined under the most critical application "quiescent air".
