Measuring body

The measuring element is a steel loaded member to which strain gauges
(SGs) are applied. The SGs are arranged so that two are extended and the
other two shortened when a force acts on the transducer.

Strain gauge covering

To protect the SG, the S9M force transducers are welded at an appropriate
place with a thin plate (Fig. 5.1). This procedure offers the SG a high level of
protection against environmental influences. In order to retain the protective
effect, this plate must not be damaged in any way.
