8 Service information
Maintenance
Soiling of the sensor element may lead to a wrong measuring result. The
sensor tip must be checked regularly for soiling and must be cleaned
when required.
Cleaning of the sensor tip
The sensor tip can be cleaned to remove dust or soiling by moving it
carefully in warm water containing a washing-up liquid. If necessary a
soft brush can be used additionally.
Do not use strong cleaners, solvents, brush or other hard ob-
jects.
Before putting it again into operation, wait until the sensor tip is com-
pletely dry.
Transport / shipment of the sensor
Before transport or shipment of the sensor, the delivered protective cap
must be placed onto the sensor tip. Avoid soiling or mechanical stress.
Recalibration
If the customer has made no other provisions, we recommend repeating
the calibration at a 12-month interval. To do so, the sensor must be sent
in to the manufacturer.
Spare parts or repair
No spare parts are available, since a repair is only possible at the manu-
facturer's facilities. In case of defects the sensors must be sent in to the
producer for repair.
If the sensor is used in systems important for operation, we recommend
you to keep a replacement sensor in stock.
Test certificates and material certificates
Every new sensor is accompanied by a certificate of compliance accord-
ing to EN10204-2.1. Material certificates are not available.
Upon request, we shall prepare, at a charge, a factory calibration certifi-
cate, traceable to national standards.
