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 amplied 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 “Specications”
■
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 fulls 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. Commissioning, operation
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 prole
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.

6.2 Electrical mounting
■
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 accord-
ance 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.
