With stainless steel force transducers, note that acids
and all materials which release ions will in general also
attack stainless steels and their welded seams. Should
there be any corrosion, this could cause the force trans­
ducer to fail. In this case, an appropriate means of pro­
tection must be provided.

Deposits

Dust, dirt and other foreign matter must not be allowed to
accumulate sufficiently to conduct any of the measuring
force around the transducer, thus invalidating the mea­
sured value. (Force shunt). Also remember to lay the
connection cable so that no force shunts are produced at
lower nominal (rated) forces (<1 kn). It is important here
for the cable to be fixed to the same component as the
lower part of the C2.

Effect of ambient pressure

The force transducer's response to changes in air pres­
sure is negligible. Please note that the force transducer
can be used at gage pressures up to 5 bar.
The following table shows the effect of air pressure on
the zero signal, subject to the nominal (rated) force being
used.
