2.1 Intended use
The pressure transmitter 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 specications contained in these operating instructions must be
observed. Improper handling or operation of the instrument outside of its techni-
cal specications 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.
Always operate the pressure transmitter within the overpressure limit.
Further important safety instructions can be found in the individual chapters
of these operating instructions.
2.2 Personnelqualication
WARNING!
Riskofinjuryshouldqualicationbeinsucient!
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 qualications 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-specic 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.

2.3 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 standard 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 transmitter.
WARNING!
Residual media in the dismounted pressure transmitter can result in a risk to
persons, the environment and equipment.
Take sucient 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 prole.
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 pressureloaded 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
GB
an electrical signal. The output signal from the pressure transmitter is amplied and
standardised.
4.2 Scope of delivery
Cross-check scope of delivery with delivery note.
5. Transport, packaging and storage
5.1 Transport
Check the pressure transmitter for any damage that may have been caused during
transportation.
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 “Specications”
Store the pressure transmitter in its original packaging in a location that fulls the condi-
tions 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.

6. Commissioning, operation
CAUTION!
Prior to commissioning, the pressure transmitter must be subjected to a
visual inspection.
Only use the pressure transmitter if it is in perfect condition with respect to
safety.
6.1 Mechanical mounting
■
The sealing faces at the instrument have to be
undamaged and clean.
■
When screwing the instrument in, the force
required to do this must not be applied through
the case, but only through the spanner ats
provided for this purpose and using a suitable
tool.
For the installation point, the valid values for
tightening torque and maximum pressure
should be taken from the high-pressure pipe
supplier's documentation.

■
When screwing in, do not cross the threads.
■
For information on tapped holes and welding sockets, see Technical information
IN 00.14 at www.wika.com.
6.2 Electrical mounting
■
The instrument must be grounded via the process connection.
■
Use the pressure transmitter with shielded cable, and ground the shield on at least
one end of the lead, if the lines are longer than 30 m (3- or 4-wire) or leave the building.
■
Select a cable diameter that matches the cable gland of the plug. Make sure that
the cable gland of the mounted plug has a tight t and that the seals are present and
undamaged. Tighten the threaded connection and check that the seal is correctly
seated, in order to ensure the ingress protection.
■
For cable outlets, make sure that no moisture enters at the cable end.
■
Observe the specications in accordance with chapter 3 “Specications”.
