Safety instructions
Appropriate use
The electrically measuring pressure transducer is a pressure‐bearing piece of
equipment and is to be used exclusively for pressure measurement tasks and
directly related control tasks. Use for any purpose other than the above is
deemed to be inappropriate.
In the interests of safety, the device should only be operated as described in
the Operating Manual. It is also essential to comply with the legal and safety
requirements for the application concerned during use. The same applies to
the use of accessories.
Each pressure‐bearing system is an energy store, particularly when the
pressure‐transmitting medium is compressible or the more it is compressed
and even more so, when the pressure medium has a high compressed volume.
If the measurement medium is released unexpectedly and forces are released
from the stored energies, this could pollute the environment, destroy
equipment or cause personal injury.
If a fine steam of hydrocarbon escapes and atomizes into the environment,
then this could lead to an explosion, even with media such as hydraulic oil,
which are usually quite harmless.
The device with its low product of pressure and volume
"PS [bar]*V[l]" complies with the basic safety requirements as per Annex I of
the "Pressure Equipment Directive 97/23/EC" and therefore conforms to
recognized engineering regulations.
It is not appropriate for use as an "accessory with a safety function", in
accordance with the regulations and this must be assessed by the user (within
the meaning of Pressure Equipment Directive 97/23/EC) for the particular
situation.
Proper and safe operation of this pressure transducer requires proper
transportation, correct storage, installation and mounting and careful operation.

General dangers of failing to follow the safety instructions
The pressure transducer corresponds to the state of the art and is failsafe.
The device may give rise to remaining dangers if it is inappropriately installed
and operated by untrained personnel.
Any person instructed to carry out installation, commissioning, maintenance or
repair of the device must have read and understood the Operating Manual and
in particular the technical safety instructions.
Accident prevention
You must make sure that the line is not under pressure when installing or
removing the pressure transducer.
Conversions and modifications
The pressure transducer must not be modified from the design or safety
engineering point of view except with our express agreement. Any modification
shall exclude all liability on our part for any damage resulting therefrom.
Qualified personnel
The pressure transducer is only to be installed and used by qualified
personnel, strictly in accordance with the specifications and with the safety
rules and regulations which follow. It is also essential to comply with the legal
and safety requirements for the application concerned during use. The same
applies to the use of accessories.
Qualified personnel means persons entrusted with the installation, assembly,
commissioning and operation of the product, who possess the appropriate
qualifications for their function.
Once the pressure device has been mounted, it must be tested.
The manometers themselves are not systems that need monitoring, but if
necessary, recurrent testing can be carried out by competent personnel (bP) as
per §10 of the European Health and Safety at Work Act (BetrSichV).
Recalibration and repair
When you send the transducer back to HBM for calibration or repair, please
specify which pressure medium is being used. It is always possible that
residual medium could be trapped in the measurement aperture. We need this
information so that we can take appropriate action and choose the correct
cleaning agent, where necessary. If we do not know the media, we may have
to refuse to calibrate or repair.

Remaining dangers
The scope of supply and performance of the transducer covers only a small
area of measurement technology. In addition, equipment planners, installers
and operators should plan, implement and respond to the safety engineering
considerations of pressure measurement technology in such a way as to
minimize remaining dangers. Prevailing regulations must be complied with at
all times. There must be reference to the remaining dangers associated with
pressure measurement technology.
Although the transducer is designed for maximum safety, safety engineering
regulations demand that burst protection is implemented around the
transducer. This is particularly important for frequent or dynamic loading.
The transducer must be protected against mechanical stresses or knocks. The
resistance of the steel of the measuring body only applies if temperatures are
never allowed to fall below or rise above the limits specified in the data sheet.
If these temperature limits are exceeded, in the event of fire, for example, the
transducer will be unusable.
If, during operation the zero signal changes by more than 5% (with no change
in the ambient conditions), the user should check the transducer to make sure
that it is not being overloaded (and causing the transducer characteristic to
vary).
Remaining dangers are indicated in this Operating Manual by the following
symbols:
Symbol: DANGER
Meaning: Maximum danger level
Warns of an imminently dangerous situation in which failure to comply with
safety requirements will result in death or serious physical injury.
Symbol: WARNING
Meaning: Possibly dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements can result in death or serious physical injury.

Symbol: CAUTION
Meaning: Potentially dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements could result in damage to property or some form of bodily
injury.
Symbols pointing out notes on use and waste disposal as well as useful
information:
Symbol: NOTE

2 Application
The pressure transducers are suitable for measuring static and dynamic liquid
and gas pressures. They are available in various measuring ranges, graded
from 1 to 3000 bar and with various electrical connection options (see Chapter
10 "Options").
All liquids and gases (vapors) that do not corrode the steels given in the spe
cifications are a suitable measurement medium. The pressure transducer is
attached by its threaded connection piece for the pressure connection and can
be mounted in any position. In the individual case, follow the actual instructions
given in Chapter 4 "Installation".
2.1 Application in potentially explosive atmospheres
On request, P3MB... transducer versions can be supplied as an option, for use
in the potentially explosive atmospheres of zones 1 and 2 in conjunction with
intrinsically safe circuits as per DIN EN 50014 and DIN EN 50020 as
intrinsically safe equipment.
These pressure transducers are category II 2 G EEx ib IIC T4 devices as per
type examination certificate no. PTB 04 ATEX 2092.
If you want to use this version of the pressure transducer, it is absolutely
essential that you take note of the document enclosed with the transducer
"Safety instructions for the P3‐Ex‐i pressure transducer (PTB 04 ATEX
2092)".

3 Structure and mode of operation
Transducers with the 0..10 bar and 0...3000 bar measuring ranges work
according to the strain gage principle.
With the 10 to 3000 bar transducers, the internal measurement tube carries the
the strain gages, which are interconnected to a Wheatstone bridge.
The strain gage application is located on the side of the tube away from the
measurement medium in a hermetically sealed reference chamber. This
protects it from environmental influences.
The transducer housings are made from stainless steel and hermetically seal
the measurement system to protect it against any harmful external influences,
so that even if the operating conditions continue to be rough, the reliability and
precision of the transducer are not impaired.
The parts of the up to 200 bar transducers that come into contact with the
media consist of 1.4301 and 1.4542 stainless steel. With the P3/500 bar to P3/
3000 bar type series, they are made of 1.4542 stainless steel.
