No maintenance of transmitter is necessary.
According to the application conditions and the measured process, a periodic check of the out-
put signal of the transmitter has to be done by skilled people (suggested period 36 months).
5.1 The following verifications are suggested by the manufacturer :
-
Leak check of the tightness of the transmitter and the process connections as often as
required.
-
Check and possible clean all wetted transmitter parts (see parts list) to make guarantee
the chemical resistance of the wetted parts. In the case of corrosion,
fi
nd out the reasons
of the corrosion and replace and adapt the concerned parts or replace the complete
transmitter with an adapted one. Please follow the replacement procedure of the mea-
suring cell described later.
-
Visual inspection of the no-wetted parts of the transmitter. Protect or replace the trans-
mitter if necessary.
