4. Transport, packaging and storage

4.1 Transport
Check the pressure sensor for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
4.2 Packaging and storage
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).
In order to protect the diaphragm, provide the process connection of the model D-21-9 with the supplied protection cap.
Permissible conditions at the place of storage:
Storage temperature: -40 ... +100 °C
■
Humidity: 45 ... 75 % relative humidity (no condensation)

5. Commissioning, operation

5.1 Mechanical mounting
Only use the pressure sensor if it is in perfect condition with respect to safety.
Prior to commissioning, the pressure sensor must be subjected to a visual inspection.
Leaking fluid is indicative of damage.
■
The diaphragm at the process connection of the model D-21-9 is a safety-relevant component and must not be
■
damaged.
Requirements for mounting point
The mounting point must meet the following conditions:
Sealing faces are clean and undamaged.
■
Sufficient space for a safe electrical installation.
■
For information on tapped holes and welding sockets, see Technical information IN 00.14 at www.wika.com.
