6. Packaging

Has everything been supplied?
Check the scope of supply:
 Completely assembled transducer
Inspect the transducer for possible damage during transportation. Should there be

any obvious damage, inform the transport company and WIKA without delay.
The transducer is purified, evacuated and double-bagged for clean-room service

and should remain packaged until installation. A protective cap is used to protect the
face sealing beads from nicks or scratches. This plug should remain in place during
storage and handling, in order to prevent damage to the bead. Therefore remove the
inner ESD (Electro-Static Discharge) bag only at the place of installation.
 Keep the packaging, as it offers optimal protection during transportation (e.g. chan-
ging installation location, shipment for repair).
