1.2 Special information
The U2A transducers are produced entirely from non-rusting materials. The
user must test for resistance to aggressive environmental conditions in each
individual case.
2 Mounting instructions
•
Handle the transducer carefully.
•
The transducer seating must be horizontal, even and, together with the
transducer mounting surface, it must be absolutely clean.
•
Dust, dirt and other particles are not to accumulate such that they affect the
load cell’s mobility and thus falsify the measured value. Use a cover plate to
protect the load cell from external mechanical influences.
•
Do not overload the transducers (e.g. by unevenly distributed loads; if
necessary, provide overload protection (e.g. supports).
•
Each transducer shoulb be shunted by a stranded copper cable (approx.
16 mm
2
) during or immediately after installation, in order to prevent any
welding or lightning currents flowing through the transducer.
