1 OPL The OPL (over pressure limit = sensor overload limit) for the sensors depends
on the lowest-rated element, with regard to pressure, of the selected
components, i.e. the process connection must be taken into consideration in
addition to the measuring cell. Also observe pressure-temperature dependency.
For the relevant standards and additional notes, see technical information.
The OPL may be applied for a limited time period.
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 notes, see technical information.
The MWP may be applied for an unlimited time.

Example
• Sensor: 10 bar (150 psi)
• Upper range limit (URL) = 10 bar (150 psi)
Turn down (TD):
• Calibrated/Adjusted measuring span: 0...5 bar
(0...75 psi)
• Lower range value (LRV) = 0 bar
• Upper range value (URV) = 5 bar (75 psi)
TD = URL
|URV - LRV|
TD = 10 bar (150 psi) =2
|5 bar (75 psi) - 0 bar (0 psi)|
In this example, the TD is thus 2:1.
This span is based on the zero point.

3.2 Device designation
3.2.1 Nameplates
• The MWP (maximum working pressure) 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. Observe temperature dependency of the MWP. The pressure values permitted at higher
temperatures can be found in the standards EN 1092-1: 2001 Tab. 18 (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.),

2220.
• The test pressure corresponds to the over pressure limit (OPL) of the device = MWP x 1.5 1).
• The Pressure Equipment Directive (2014/68/EU) uses the abbreviation "PS".
The abbreviation "PS" corresponds to the MWP (maximum working pressure) of the
measuring device.

• Devices with a G 1 1/2 thread:
When screwing the device into the tank, the flat seal has to be positioned on the sealing
surface
of the process connection. To avoid additional strain on the process isolating diaphragm, the
thread should never be sealed with hemp or similar materials.
• Devices with NPT threads:
– Wrap Teflon tape around the thread to seal it.
– Tighten the device at the hexagonal bolt only. Do not turn at the housing.
– Do not overtighten the thread when screwing. Max. torque: 20 to 30 Nm (14.75 to 22.13
lbf ft)
• For the following process connections a tightening torque of max. 40 Nm (29.50 lbf ft)
is required:
– Thread ISO228 G1/2 (Order option "1A" or "1B")

Risk of damage to process connection!
Risk of injury!
‣Sensor modules with PVDF thread must be installed with the mounting bracket provided!
WARNING
!
Material fatigue from pressure and temperature!
Risk of injury if parts burst! The thread can become loose if exposed to high pressure and
temperatures.
‣The integrity of the thread must be checked regularly and the thread may need to be
re-tightened with the maximum tightening torque of 7 Nm (5.16 lbf ft). Teflon tape is
recommended for sealing the ½" NPT thread.
4.4 Installation instructions
• Due to the orientation of the Cerabar S, there may be a shift in the zero point, i.e. when the
container is empty or partially full, the measured value does not display zero. You can correct
this zero point shift either directly at the device using the "E" key or by remote operation. See
ä27, "Function of the operating elements – onsite display not connected" or
ä34, "Position adjustment".
• To ensure optimal readability of the onsite display, it is possible to rotate the housing up to
380°. ä16, "Rotating the housing".
• Endress+Hauser offers a mounting bracket for installing on pipes or walls.
ä16, "Wall and pipe mounting (optional)".

4.4.1 Installation instructions
NOTICE
Damage to the device!
If a heated Cerabar S is cooled during the cleaning process (e.g. by cold water), a vacuum
develops for a short time, whereby moisture can penetrate the sensor through the pressure
compensation (1).
‣If this is the case, mount the Cerabar S with the pressure compensation (1) pointing
downwards.
• Keep the pressure compensation and GORE-TEX®filter (1) free from contamination and
water.
• Cerabar S devices are mounted as per the norms for a manometer (DIN EN 837-2). We
recommend the use of shutoff devices and siphons. The orientation depends on the
measuring application.
• Do not clean or touch process isolating diaphragms with hard or pointed objects.
• To comply with ASME-BPE requirements regarding cleanability (Part SD Cleanability), the
device must be installed as follows:

Pressure measurement in gases
Mount Cerabar S with shutoff device above the tapping point so that
any condensate can flow into the process.
Pressure measurement in steam
• Use siphons for pressure measurement in steam. The siphon reduces the temperature to
almost ambient temperature. Preferably mount the Cerabar S with the siphon below the
tapping point.
Advantages:
– defined water column only causes minimal/negligible measured errors
– only minimal/negligible thermal effects on the device
Mounting above the tapping point is also possible. Pay attention to the maximum permitted
ambient temperature of the transmitter!
• Fill the siphon with liquid before commissioning.
Pressure measurement in liquids
Mount Cerabar S with shutoff device below or at the same level as the tapping point.
4.4.2 Seal for flange mounting
NOTICE
Corrupted measurement results.
The seal is not allowed to press against the process isolating diaphragm as this could affect the
measurement result.
‣Ensure that the seal is not touching the process isolating diaphragm.

T15 andT17 housing: Loosen setscrew with a 3 mm (0.12 in) Allen key.
2. Rotate housing (max. up to 380 °).
3. Retighten setscrew with 1 Nm (0,74 lbf ft.
4.4.5 Closing the housing cover
NOTICE
Devices with EPDM cover seal - transmitter leakiness!
Mineral-based, animal-based or vegetable-based lubricants cause the EPDM cover seal to swell
and the transmitter to become leaky.
‣The thread is coated at the factory and therefore does not require any lubrication.
NOTICE
The housing cover can no longer be closed.
Damaged thread!
‣When closing the housing cover, please ensure that the thread of the cover and housing are
free from dirt, e.g. sand.If you feel any resistance when closing the cover, check the thread
on both again to ensure that they are free from dirt.

The covers for the terminal and electronics compartment are hooked into the casing and closed
with a screw. These screws should be finger-tightened (2 Nm (1.48 lbf ft)) to the stop to ensure
that the covers sit tightly.
4.5 Post-installation check
After installing the device, carry out the following checks:
• Are all the screws firmly tightened?
• Are the housing covers screwed down tight?

!
Risk of electric shock!
If the operating voltage is > 35 VDC: Dangerous contact voltage at terminals.
‣In a wet environment, do not open the cover if voltage is present.
WARNING
!
Limitation of electrical safety due to incorrect connection!
• When using the measuring device in hazardous areas, installation must comply with the
corresponding national standards and regulations and the Safety Instructions or Installation
or Control Drawings.
• Devices with integrated overvoltage protection must be grounded.
• Protective circuits against reverse polarity, HF influences and overvoltage peaks are
integrated.

Risk of electric shock and/or explosion!
‣When using the measuring device in hazardous areas, installation must comply with the
corresponding national standards and regulations and the Safety Instructions or Installation

Taking 4 to 20 mA test signal
A 4 to 20 mA signal may be measured via the positive and test terminal without interrupting
the measurement. The minimum supply voltage of the device can be reduced by simply
replugging the jumper. As a result, operation is also possible with lower voltage sources. To keep
the measured error below 0.1%, the current measuring device should exhibit an internal
resistance of < 0.7 . Observe the position of the jumper in accordance with the following table.
