Structure and mode of operation

3.1 Measuring body

The measuring element is a stainless 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 U93 force transducers are welded at an appropriate
place with a thin metal plate. This procedure offers the SG a high protection
against environmental influences. In order to retain the protective effect, this
plate must not be damaged in any way; see section 5.2 on page 12.
