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

Means that important information about the product or its handling is being

given.

Meaning: CE mark

The CE mark enables the manufacturer to guarantee that the product complies

with the requirements of the relevant EC directives (the Declaration of

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.
