CORROSION PROTECTION AND MAINTENANCE

Protect load cells against chemicals that could attack the cable or the steel of the hous­
ing.
Notice
Acids and all substances that release ions also attack stainless steels and their weld
seams.
The resulting corrosion could cause the transducer to fail. If this is the case, you must pro­
vide appropriate means of protection.
The transducer is basically maintenance free.
Dust, dirt and other foreign matter must not be allowed to accumulate sufficiently to di­
vert some of the measuring force onto the housing, thus distorting the measured value
(force shunt).
Do not use hard or pointed objects to clean the transducer. The transducer achieves an IP
rating of IP68 (test conditions: 100 hours under 1 m water column) or, optionally, IP69K
(water at high pressure, steam cleaning), as per DIN EN 60529. The transducer is there­
fore suitable for wet cleaning. Despite this, the transducer should be protected against
the long-term effects of moisture.
