2. Safety
2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate pressure transmitter has
been selected in terms of measuring range, design and specic measuring conditions.
Non-observance can result in serious injury and/or damage to equipment.
WARNING!
■
Open the connections only after the system has been depressurised.
■
Observe the working conditions in accordance with chapter 3 “Specications”.
■
Always operate the pressure transmitter within the overpressure limit.
Further important safety instructions can be found in the individual chapters of these operating
instructions.
2.1 Intended use
The pressure transmitter is used to convert pressure into an electrical signal indoors and outdoors.
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 pressure transmitter outside of its technical 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 knowledge 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 standard regulations, the appropriate existing codes or
regulations must also be followed.
WARNING!
Residual media in the dismounted pressure transmitter 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.

RoHS directive
1) The existence of strong electromagnetic elds in a frequency range of < 2.7 GHz can result in increased measuring errors up to 1 %. Do not install the instruments in
the vicinity of strong electromagnetic sources of interference (e.g. transmitting devices, radio equipment), or use sheath current lters where applicable.
For special model numbers, e.g. S-11000, please note the specications stated on the delivery note.
For further specications see WIKA data sheet PE 81.02 and the order documentation.
4. Design and function
4.1 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
transmitter is amplied and standardised. The output signal is proportional to the measured pressure.
4.2 Scope of delivery
Cross-check the scope of delivery with the 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:
■
Storage temperature: see chapter 3 “Specications”
■
Humidity: 45 ... 75 % relative humidity
Avoid exposure to the following factors:
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Potentially explosive environments, ammable atmospheres
Store the pressure transmitter in its original packaging in a location that fulls the conditions listed above. If the original
packaging is not available, pack and store the instrument as described below:
1. Place the protection cap on the process connection
2. Place the instrument, along with shock-absorbent material, in the packaging.
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.
■
Leaking uid is indicative of damage.
■
Check the diaphragm of the process connection for any damage.
■
Only use the pressure transmitter if it is in perfect condition with respect to safety.

6.1 Mechanical mounting
■
Remove the protection cap not until shortly before installation.
■
Ensure that the diaphragm of the process connection is not damaged during
installation.
■
The sealing faces at the pressure transmitter and the measuring point always
have to be clean.
■
Only ever screw in, or unscrew, the instrument using the spanner ats. Never
use the case or the cooling element as a working surface.
■
The correct torque depends on the dimensions of the process connection and
the gasket used (form/material).
■
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.
■
Attach the connector and screw it in hand-tight. The assembly of the angular
connector is described in chapter 6.2 “Electrical mounting”.
Sealing
Correct sealing of the process
connections with parallel threads at
the sealing face
 must be made
using suitable at gaskets, sealing
rings or WIKA prole sealings. The
sealing of tapered threads (e.g.
NPT threads) is made by providing
the thread with additional sealing
material such as, for example, PTFE
tape (EN 837-2).
For further information on seals see WIKA data sheet AC 09.08 or under www.wika.com.

■
The instrument must be earthed via the process connection.
■
For instruments with voltage output, use shielded cable, and, if the cables are longer than 30 m or they leave the
building, earth the shield at least at one end of the cable.
■
In North America, use the instrument in line with "class 2 circuits" or "class 2 power units" in accordance with CEC
(Canadian Electrical Code) or NEC (National Electrical Code).
■
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 a tight seal.
■
For cable outlets, make sure that no moisture enters at the cable end.
