Channel with fill fluid
Metallic membrane
Pressure

The pressure acts on the membrane of the diaphragm seal and is transferred to theinternal membrane by a fill fluid. The internal membrane is deflected. A fill fluid transfers
the pressure to the measuring element on which a resistance bridge is located. The
pressure-dependent change in the bridge output voltage is measured and evaluated.
Advantages:• Depending on the version, can be used for pressures up to 400 bar (6 000 psi) and for
extreme process temperatures• High long-term stability• High overload resistance• Standard device (without diaphragm seal): secondary containment for enhanced
integrity
Applications for diaphragm seals
Diaphragm seal systems are used if the process and the device need to be separated.
Diaphragm seal systems offer clear advantages in the following instances:• In the case of extreme process temperatures - through the use of temperature isolators
or capillaries• In the case of strong vibrations - decouple the process from the device by using acapillary• In the case of aggressive or corrosive media - through the use of high-durability
membrane materials• In the case of media that crystallize or contain solids - through the choice of suitablecoatings• In the case of heterogeneous and fibrous process media• If extreme measuring point cleaning is necessary, or in the event of very damp mounting
locations• For mounting locations that are difficult to access

• Do not remove the protection on the membrane until just before installation.
Always firmly tighten the housing cover and the cable entries.
1.

Counter-tighten the cable entries.

2.

Tighten the coupling nut.

5.1.2

Installation instructions• The standard devices (without diaphragm seals) are mounted according to the sameguidelines as pressure gauges (DIN EN837-2)• To ensure optimal readability of the local display, adjust the housing and local display• Endress+Hauser offers a mounting bracket to mount the device on pipes or walls• Use flushing rings for flanges, flange seals and pancake seals if buildup or clogging canbe expected at the membrane• The flushing ring is clamped between the process connection and the flange, flange
seal or pancake seal
• Material buildup in front of the membrane is flushed away, and the pressure chamber
is vented, via the two lateral flushing holes• When measuring in media containing solids (e.g. dirty liquids), installing separators anddrain valves is useful for capturing and removing sediment• Using a valve manifold allows for easy commissioning, installation and maintenancewithout interrupting the process• When mounting the device, establishing the electrical connection and during operation:
prevent the penetration of moisture into the housing• Point the cable and plug downwards as much as possible to prevent moisture fromentering (e.g. rainwater or condensation)

5.1.3

Installation instructions for thread• Device with G 1 ½" thread:Place the flat seal on the sealing surface of the process connection
Avoid additional strain on the membrane: do not seal the thread with hemp or similarmaterials• Device with NPT thread:• Wrap Teflon tape around the thread to seal it• Tighten the device at the hexagon bolt only; do not turn it by the housing• When screwing in, do not overtighten the thread; tighten the NPT thread to therequired depth according to the standard• For the following process connections, a tightening torque of max. 40 Nm (29.50 lbf ft)

Mounting

Installation instructions for devices with diaphragm seals

NOTICE
Improper handling!
Damage to the device!
‣ The diaphragm seal and pressure transmitter form a closed, calibrated system which
has been filled with diaphragm seal fill fluid. Never open any of the holes for fill fluid.
‣ Ensure strain relief to prevent the capillary from bending (bending radius ≥100 mm (3.94 in)).
‣ Do not use capillaries as a carrying aid for the diaphragm seals.
‣ Observe the application limits of the fill fluid.
General information
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, a position adjustment can cause the measuring cell to go over range(position adjustment due to zero point offset, caused by the orientation of the fill fluid
liquid column). Perform zero adjustment if necessary.
For devices with a capillary, use a suitable bracket (mounting bracket) for mounting.
When mounting, sufficient strain relief must be provided for the capillary to prevent thecapillary from bending (capillary bending radius ≥ 100 mm (3.94 in)).
Mount the capillary so that it is vibration-free (in order to avoid additional pressure
fluctuations).
Do not mount capillaries in the vicinity of heating or cooling lines and protect themagainst direct sunlight.
More detailed installation instructions are provided in the Applicator"Sizing Diaphragm Seal".

5.1.5

Orientation

NOTICE
Damage to the device!
If a heated device is cooled during a cleaning process (e.g. by cold water), a vacuum
develops for a short time. As a result of this, moisture can enter the measuring cell via thepressure compensation element (1).
‣ Mount the device as follows.

Mounting

Thermal insulation when mounting with a "Temperatureisolator" diaphragm seal typeUse of temperature isolators in the event of constant extreme medium temperatures whichcause the maximum permissible electronics temperature of +85 °C (+185 °F) to be
exceeded. Diaphragm seal systems with temperature isolators can be used up to a
maximum temperature of +400 °C (+752 °F) depending on the fill fluid used. For details
see the Technical Information. To minimize the influence of rising heat, mount the device
horizontally or with the housing pointing downwards. The additional installation heightbrings about a zero point shift due to the hydrostatic column in the temperature isolator.
This zero point shift can be corrected on the device.
The maximum ambient temperature Ta at the transmitter depends on the maximum
process temperature Tp.
The maximum process temperature depends on the fill fluid used.

Process pressure range

Pressure specifications

LWARNING
The maximum pressure for the device depends on the lowest-rated component withregard to pressure (components are: process connection, optional mounted parts oraccessories).
‣ Only operate the device within the specified limits for the components!
‣ MWP (maximum working pressure): The MWP is specified on the nameplate. Thisvalue refers to a reference temperature of +20 °C (+68 °F) and may be applied to thedevice for an unlimited time. Note temperature dependence of MWP. For flanges, referto the following standards for the permitted pressure values at higher temperatures:
EN 1092-1 (with regard to their stability/temperature property, the materials 1.4435
and 1.4404 are grouped together under EN 1092-1; the chemical composition of thetwo materials can be identical.), ASME B 16.5a, JIS B 2220 (the latest version of thestandard applies in each case). MWP data that deviate from this are provided in therelevant sections of the Technical Information.
‣ The overpressure limit is the maximum pressure a device may be subjected to during atest. It is greater than the maximum working pressure by a certain factor. This valuerefers to a reference temperature of +20 °C (+68 °F).
‣ The Pressure Equipment Directive (2014/68/EU) uses the abbreviation "PS". The
abbreviation "PS" corresponds to the MWP (maximum working pressure) of the device.
‣ In the case of measuring cell range and process connection combinations where theoverpressure limit (OPL) of the process connection is smaller than the nominal value ofthe measuring cell, the device is set at the factory, at the very maximum, to the OPL
value of the process connection. If the entire measuring cell range must be used, selecta process connection with a higher OPL value (1.5 x PN; MWP = PN).
‣ Oxygen applications: do not exceed values for Pmax and Tmax.
Burst pressure
As of the specified burst pressure, the complete destruction of the pressure-bearing parts
and/or a device leak must be expected. It is therefore imperative to avoid such operating
conditions by carefully planning and sizing your facility.
Ultrapure gas applications

Endress+Hauser

Endress+Hauser also offers devices for special applications, such as for ultrapure gas, thatare cleaned of oil and grease. No special restrictions regarding the process conditions apply
to these devices.

Thermal insulation when mounting with a "Temperature isolator" diaphragm sealtype
Use of temperature isolators in the event of constant extreme medium temperatures whichcause the maximum permissible electronics temperature of +85 °C (+185 °F) to be
exceeded. Diaphragm seal systems with temperature isolators can be used up to a
maximum temperature of +400 °C (+752 °F) depending on the fill fluid used. For details
see the Technical Information. To minimize the influence of rising heat, mount the device
horizontally or with the housing pointing downwards. The additional installation heightbrings about a zero point shift due to the hydrostatic column in the temperature isolator.
This zero point shift can be corrected on the device.
The maximum ambient temperature Ta at the transmitter depends on the maximum
process temperature Tp.
The maximum process temperature depends on the fill fluid used.
