OPL: The OPL (overpressure limit = measuring cell overload limit) for the 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. Pay attention to the pressure/temperature dependency.
2
The MWP (maximum working pressure) for the measuring cells depends on the lowest-rated element, withregard to pressure, of the selected components, i.e. the process connection has to be taken into considerationin addition to the measuring cell. Pay attention to the pressure/temperature dependency. The MWP may be
applied at the device for an unlimited period of time. The MWP can be found on the nameplate.

Pressure

The pressure deflects the metallic membrane of the measuring cell. A fill fluid transfers the pressure
to a Wheatstone bridge (semiconductor technology). The pressure-dependent change in the bridge
output voltage is measured and evaluated.
Advantages:• Can be used for high pressures• High long-term stability• High overload resistance• Secondary containment for enhanced integrity• Significantly reduced thermal effect e.g. compared to diaphragm seal systems with capillaries

measuring element on which a resistance bridge is located. The pressure-dependent change in thebridge 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 a capillary• In the case of aggressive or corrosive media - through the use of high-durability membranematerials• In the case of media that crystallize or contain solids - through the choice of suitable coatings• 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 accessMeasuring system

Orientation• A position-dependent zero point shift (when the vessel is empty the measured value does not
display zero) can be corrected• Diaphragm seals also shift the zero point, depending on the installation position• The use of shutoff devices and/or water pocket pipes is recommended for mounting• The orientation depends on the measuring application

Installation instructions• The standard devices (without diaphragm seals) are mounted according to the same guidelines aspressure 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 can be
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 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• When mounting the device, establishing the electrical connection and during operation: preventthe penetration of moisture into the housing• Point the cable and plug downwards as much as possible to prevent moisture from entering (e.g.
rainwater or condensation)

Installation instructions fordevices with diaphragm seals

General information
A diaphragm seal together with the transmitter form a closed, calibrated system, which has been
filled through openings in the diaphragm seal and in the transmitter's measurement system. These
openings are sealed and must not be opened.
In the case of devices with diaphragm seals and capillaries, the zero point shift caused by thehydrostatic pressure of the filling liquid column in the capillaries must be taken into account whenselecting the measuring cell. Perform zero adjustment if necessary. 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 liquidcolumn).
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 the capillary
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 them against direct
sunlight.
More detailed installation instructions are provided in the Applicator "Sizing Diaphragm Seal".
Vacuum applications
In vacuum applications, ideally use pressure transmitters with a ceramic membrane (oil-free).
In vacuum applications, mount the pressure transmitter below the diaphragm seal. This prevents
additional vacuum loading of the diaphragm seal caused by the presence of fill fluid in the capillary.
If the pressure transmitter is mounted above the diaphragm seal, do not exceed the maximum height
difference h1. The height difference h1 is shown in the Applicator "Sizing Diaphragm Seal".

Mounting the device
Pressure measurement in gases
Mount the device with the shutoff device above the tapping point so that any condensate can flow
into the process.
Pressure measurement in steam
Observe the maximum permitted ambient temperature of the transmitter!
Mounting:• Ideally, mount the device with the O-shaped siphon below the tapping point
The device may also be mounted above the tapping point• Fill the siphon with liquid before commissioning
Advantages of using siphons:• Protects the measuring device from hot, pressurized media due to the formation and collection ofcondensate• Attenuation of water hammer• The defined water column only causes minimal (negligible) measured errors and minimal(negligible) thermal effects on the device
For technical data (e.g. materials, dimensions or order numbers), see the accessory document
SD01553P.
Pressure measurement in liquids
Mount the device with the shutoff device below or at the same level as the tapping point.
Level measurement• Always mount the device below the lowest measuring point• Do not install the device at the following positions:• In the filling curtain• In the tank outlet• In the suction area of a pump
• At a point in the tank which could be affected by pressure pulses from the agitator• Mount the device downstream from a shutoff device: the calibration and function check can be
carried out more easily
Mounting bracket for device or separate housing
The device or the separate housing can be mounted on walls or pipes (for pipes with a diameter of 1¼" to 2") using the mounting bracket.

Oxygen applications (gaseous)
Oxygen and other gases can react explosively to oils, grease and plastics. The following precautions
must be taken:• All components of the system, such as devices, must be cleaned in accordance with national
requirements.
• Depending on the materials used, a certain maximum temperature and a maximum pressure mustnot be exceeded for oxygen applications.
The cleaning of the device (not accessories) is provided as an optional service.
• pmax: Depends on the lowest-rated element, with regard to pressure, of the selected components:
Over pressure limit (OPL) of the measuring cell, process connection (1.5 x PN) or fill fluid(80 bar (1 200 psi))• Tmax: 60 °C (140 °F)

Process pressure range

Pressure specifications

LWARNING
The maximum pressure for the device depends on the lowest-rated component with regard topressure (components are: process connection, optional mounted parts or accessories).
‣ Only operate the device within the specified limits for the components!
‣ MWP (maximum working pressure): The MWP is specified on the nameplate. This value refers
to a reference temperature of +20 °C (+68 °F) and may be applied to the device for an unlimited
time. Note temperature dependence of MWP. For flanges, refer to the following standards forthe 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 the two materials can be identical.), ASME B 16.5a, JIS B 2220 (thelatest version of the standard applies in each case). MWP data that deviate from this areprovided in the relevant sections of the Technical Information.
‣ The overpressure limit is the maximum pressure a device may be subjected to during a test. It isgreater than the maximum working pressure by a certain factor. This value refers 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 the overpressure
limit (OPL) of the process connection is smaller than the nominal value of the measuring cell, thedevice 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, select a 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 adevice leak must be expected. It is therefore imperative to avoid such operating conditions bycarefully planning and sizing your facility.
Ultrapure gas applications

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

Hydrogen applications

A gold-coated metallic membrane offers universal protection against hydrogen diffusion, both ingas applications and in applications with water-based solutions.

Steam applications andsaturated steam applications

For steam and saturated steam applications: Use a device with a metallic membrane or provide awater pocket pipe for temperature decoupling when installing.

Thermal insulation

Thermal insulation with diaphragm seal directly mounted
The device may only be insulated up to a certain height. The maximum permitted insulation height isindicated on the device and applies to an insulation material with a heat conductivity ≤ 0.04 W/(m xK) and to the maximum permitted ambient and process temperature. The data were determined
