Structure and mode of operation

S2M
4.1

Measuring body

The measuring body is an aluminum bending beam on
which strain gauges (SG) are installed. The SG are
arranged so that two are stretched and the other two
compressed when a force acts on the transducer.

Strain gauge covering agent

To protect the SG, the S2M force transducers are potted
with a plastic material at an appropriate place. This pro­
cedure offers the SG high protection against environ­
mental influences. To retain the protective capacity and
ensure permanent functionality, the force transducer pot­
ting material must not become damaged.

Disturbance variables

Torsion, bending and lateral loads are disturbance vari­
ables and therefore to be avoided.
