Measuring principle process pressure
measurement
Devices with ceramic process isolating diaphragm (Ceraphire®)
The ceramic sensor is an oil-free sensor, i.e. the process pressure acts directly on the robust ceramic
process isolating diaphragm and causes it to deflect. A pressure-dependent change in capacitance is
measured at the electrodes of the ceramic substrate and the process isolating diaphragm. The
measuring range is determined by the thickness of the ceramic process isolating diaphragm.
Advantages:
• Guaranteed overload resistance up to 40 times the nominal pressure
• The ultrapure 99.9% ceramic (Ceraphire®, see also "www.endress.com/ceraphire") ensures:
– Extremely high chemical durability
– High mechanical durability
• Can be used in absolute vacuum
• Small measuring ranges
A0020465
1 Air pressure (gauge pressure sensors)
2 Ceramic substrate
3 Electrodes
4 Ceramic process isolating diaphragm
Devices with metallic process isolating diaphragm
The process pressure deflects the metal process isolating diaphragm of the sensor and 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 process pressures
• Fully welded sensor
• Slim, flush-mounted process connections available

• Behavior in the event of overvoltage (>30 V):
The device works continuously up to 34 V DC without damage. If the supply voltage is exceeded,
the specified characteristics are no longer guaranteed.
• Behavior in the event of undervoltage:
If the supply voltage falls below the minimum value, the device switches off in a defined manner

Influence of the installation position
• Moisture must not penetrate the housing when mounting the device, establishing the electrical
connection and during operation.
• Point the cable and connector downwards where possible to prevent moisture from entering (e.g.
rain or condensation water).
Any orientation is possible. However, the orientation may cause a zero point shift i.e. the measured
value does not show zero when the vessel is empty or partially full.

Mounting instructions for 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 the
BAM requirements.
• Dependent on the materials used, a certain maximum temperature and a maximum pressure for
oxygen applications must not be exceeded.
• The following table lists devices (devices only, not accessories or enclosed accessories), which are
suitable for gaseous oxygen applications.

section.
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.
MWP (maximum working pressure): The MWP (maximum working pressure) is specified on the
‣
nameplate. This value is based on a reference temperature of +20 °C (+68 °F) and may be applied
to the device for an unlimited period of time. Observe the temperature dependency of the MWP.
OPL (over pressure limit): The test pressure corresponds to the over pressure limit of the sensor
‣
and may only be applied temporarily to ensure that the measurement is within the specifications
and no permanent damage develops. In the case of sensor range and process connections where
the over pressure limit (OPL) of the process connection is smaller than the nominal value of the
sensor, the device is set at the factory, at the very maximum, to the OPL value of the process
connection. If you want to use the entire sensor range, select a process connection with a higher
OPL value.
Oxygen applications: In oxygen applications, the values for "p
‣
may not be exceeded .
Devices with ceramic process isolating diaphragm: avoid steam hammering! Steam hammering
‣
can cause zero point drifts. Recommendation: Residue (water droplets or condensation) may
remain on the process isolating diaphragm following CIP cleaning and can result in local steam
hammering the next time steam cleaning takes place. In practice, drying the process isolating
diaphragm (e.g. by blowing) has proved to prevent steam hammering.

• The following dimensions have been rounded up to whole measurements.
• Exact dimensions are available in the Product Configurator on the Endress+Hauser website:

Design, dimensions Device height
The device height is calculated from
• the height of the electrical connection
• the height of the housing and
• the height of the individual process connection.
The individual heights of the components are listed in the following sections. To calculate the device
height simply add up the individual heights of the components. Where applicable also take into
consideration the installation distance (space that is used to install the device). You can use the
following table for this purpose:

Pressure equipment (with a maximum allowable pressure PS ≤ 200 bar (2 900 psi)) can be classified
as pressure accessories in accordance with Pressure Equipment Directive 2014/68/EU. If the
maximum allowable pressure is ≤ 200 bar (2 900 psi) and the pressurized volume of the pressure
equipment is ≤ 0.1 l, the pressure equipment is subject to the Pressure Equipment Directive (cf.
Pressure Equipment Directive 2014/68/EU, Article 4, point 3). The Pressure Equipment Directive
only requires that the pressure equipment shall be designed and manufactured in accordance with
the "sound engineering practice of a Member State".
Reasons:
• Pressure Equipment Directive (PED) 2014/68/EU Article 4, point 3
• Pressure equipment directive 2014/68/EU, Commission's Working Group "Pressure", Guideline
A-05 + A-06
Note:
A partial examination shall be performed for pressure instruments that are part of safety equipment
for the protection of a pipe or vessel from exceeding allowable limits (safety accessory in accordance
with Pressure Equipment Directive 2014/68/EU, Article 2, point 4).
Pressure equipment with allowable pressure > 200 bar (2 900 psi)
Pressure equipment designated for application in every process fluid having a pressurized volume of
<0.1 l and a max. allowable pressure PS > 200 bar (2 900 psi) shall satisfy the essential safety
requirements set out in Annex I of the Pressure Equipment Directive 2014/68/EU. According to
Article 13 pressure equipment shall be classified by category in accordance with Annex II. The
conformity assessment of the pressure equipment shall be determined by the category I under
consideration of the above-mentioned low pressurized volume. These devices shall be provided with
CE marking.
Reasons:
• Pressure Equipment Directive 2014/68/EU, Article 13, Annex II
• Pressure equipment directive 2014/68/EU, Commission's Working Group "Pressure", Guideline
A-05
Note:
A partial examination shall be performed for pressure instruments that are part of safety equipment
for the protection of a pipe or vessel from exceeding allowable limits (safety accessory in accordance
with Pressure Equipment Directive 2014/68/EU, Article 2, point 4).
