Structure and mode of operation

3.1 Measuring body

The measuring element is a steel loaded member to which strain gages (SG)
are applied. The SG are arranged so that two are stretched and the other two
compressed when a force acts on the transducer.

3.2 Strain gage covering

To protect the SG, the S9M force transducers are welded at an appropriate
place with a thin plate (Fig. 3.1). This procedure offers the SG a high protec­
tion against environmental influences. In order to retain the protective effect,
this plate must not be damaged in any way.
