Series Z6... load cells are hermetically encapsulated and are therefore not at all sensitive
to the influence of moisture and humidity. The transducers achieve protection class IP68
(test conditions: 100 hours under 1 m water column) as per DIN EN60529. Nevertheless,
the load cells must be protected against constant humidity and moisture.
Protection against corrosion
The load cell must be protected against chemicals that could attack the transducer body
steel, or the cable.
Notice
Acids and all substances that release ions also attack stainless steels and their welded
seams.
Should there be any corrosion, this could cause the transducer to fail. If this is the case,
you must provide appropriate means of protection.
Explosion protection version option
The ambient temperature range specified on the transducer must not be exceeded.
Deposits
Dust, dirt and other foreign matter must not be allowed to accumulate sufficiently to
divert some of the measuring force onto the housing, thus invalidating the measured
value (force shunt).
