Structure and mode of operation
5.1
Transducer
The measuring body is a steel loaded member on which strain gages (SG) are
installed. The influence of a force deforms the measuring body
,
so there is
deformation in places where the strain gages are installed. The SG are
attached so that two are extended and two are shortened. The strain gages are
wired to form a Wheatstone bridge circuit. They change their ohmic resistance
in proportion to their change in length and so unbalance the Wheatstone
bridge. If there is an excitation voltage, the circuit produces an output signal
proportional to the change in resistance and thus also proportional to the
applied force. The strain gage arrangement is chosen to compensate, as much
as possible, for parasitic forces and moments (e.g. lateral forces and torques),
as well as the effects of temperature.
5.2
Strain gage covering agent
The force transducers have thin cover plates attached to the base to protect
the SGs. In combination with the integrated cable, the steel versions achieve
equipment protection level IP64. In order to retain the protective effect, these
plates must not be removed or damaged in any way.
