2. Safety

WARNING!

Before installation, commissioning and operation, ensure that the appropri-

ate pressure sensor has been selected in terms of measuring range, design

and specic measuring conditions.

The operator must ensure the compatibility of the uid with the material

used. Where the medium is hydrogen, contact the manufacturer.

The uid must not be contaminated with abrasive substances.

Non-observance can result in serious injury and/or damage to the equipment.

2. Safety

WARNING!

■

Open the connections only after the system has been depressurised.

■

Observe the working conditions in accordance with chapter 3 “Specica-

tions”.

■

Always operate the pressure sensor within the overpressure limit.

Further important safety instructions can be found in the individual chapters

of these operating instructions.

2.1 Intended use

The pressure sensor is used to convert pressure into an electrical signal.

The instrument has been designed and built solely for the intended use described here,

and may only be used accordingly.

The technical specications contained in these operating instructions must be

observed. Improper handling or operation of the instrument outside of its techni-

cal specications requires the instrument to be taken out of service immediately and

inspected by an authorised WIKA service engineer.

The manufacturer shall not be liable for claims of any type based on operation contrary

to the intended use.

2.2 Personnelqualication

WARNING!

Riskofinjuryshouldqualicationbeinsucient!

Improper handling can result in considerable injury and damage to equipment.

The activities described in these operating instructions may only be carried

out by skilled personnel who have the qualications described below.

Skilled personnel

Skilled personnel are understood to be personnel who, based on their technical training,

knowledge of measurement and control technology and on their experience and knowl-

edge of country-specic regulations, current standards and directives, are capable of

carrying out the work described and independently recognising potential hazards.

Special operating conditions require further appropriate knowledge, e.g. of aggressive

media.

2. Safety

2.3 Special hazards

WARNING!

For hazardous media such as oxygen, acetylene, ammable or toxic gases

or liquids, and refrigeration plants, compressors, etc., in addition to all stand-

ard regulations, the appropriate existing codes or regulations must also be

followed.

WARNING!

No plant conditions are permitted that could lead to the formation of atomic

hydrogen in the connection channel of the pressure sensor.

WARNING!

Residual media in the dismounted pressure sensor can result in a risk to

persons, the environment and equipment.

Take sucient precautionary measures.

Do not use this instrument in safety or emergency stop devices. Incorrect use

of the instrument can result in injury.

Should a failure occur, aggressive media with extremely high temperature and

under high pressure or vacuum may be present at the instrument.

Service life

On request, since the service life depends on the actual pressure prole.

Despite its excellent load cycle stability a permanent load cycle stability is only given

conditionally.This is due to the extreme loadings faced by the highly pressurised

materials.This applies particularly to dynamic applications. Accordingly, the pressure-

loaded parts of the HP-2 are considered as wear parts that are not covered by the

warranty.

4. Design and function / 5. Transport, packaging and ...

4. Design and function

4.1 Short description

The prevailing pressure is measured at the sensor element through the deformation of a

diaphragm. By supplying power, this deformation of the diaphragm is converted into an

electrical signal. The output signal from the pressure sensor is amplied and standard-

ised.

4.2 Scope of delivery

Cross-check scope of delivery with delivery note.

5. Transport, packaging and storage

5.1 Transport

Check the pressure sensor for any damage that may have been caused during transpor-

tation.

Obvious damage must be reported immediately.

5.2 Packaging

Do not remove packaging until just before mounting.

Keep the packaging as it will provide optimum protection during transport (e.g. change

in installation site, sending for repair).

5.3 Storage

Permissible conditions at the place of storage:

see chapter 3 “Specications”

Store the pressure sensor in its original packaging in a location that fulls the conditions

listed above.

WARNING!

Before storing the instrument (following operation), remove any residual

media.This is of particular importance if the medium is hazardous to health,

e.g. caustic, toxic, carcinogenic, radioactive, etc.
