Has everything been supplied?
Check the scope of supply:
Completely assembled pressure transmitters; with flush version N-11 including pre-

assembled sealings and protection cap.
 Inspect the pressure transmitter for possible damage during transportation. Should
there be any obvious damage, inform the transport company and WIKA without delay.
 Keep the packaging, as it offers optimal protection during transportation (e.g. chan-
ging installation location, shipment for repair).
 Ensure that the pressure connection thread and the connection contacts will not be
damaged.
In order to protect the diaphragm, the pressure connection of the instrument N-11 is provided
with a special protection cap.
Remove this protection cap by hand only just before installing the pressure transmitter

in order to prevent any damage to the diaphragm or the thread.
Keep the protection cap of the pressure connection thread and the diaphragm for


It is necessary that before starting the pressure transmitter you test the diaphragm visually, as
this is a safety-relevant component.
Pay attention to any liquid leaking out, for this points to a diaphragm

damage.
Check the diaphragm visually for any damage (N-11).

Warning
 Use the pressure transmitter only if the diaphragm is undamaged.
 Use the pressure transmitter only if it is in a faultless condition as far as the
safety-relevant features are concerned.

Mechanical connection

max.
50 Nm
Sealing
Protect the diaphragm against any contact with abrasive substances and

pressure peaks and do not touch it with tools. If you damage the diaphragm,
no intrinsic safety can be guaranteed (ATEX)!
Warning
 Ensure that under hazardous ennvironment the pressure transmitter is
mounted in a shielded section and protect it against shocks.
 Observe the technical data for the use of the pressure transmitter in connec-
tion with aggressive / corrosive media and for the avoidance of mechanical
hazards.
