Functional Principle
The force to be measured is introduced via a top plate and
distributed on the 3-component force sensors arranged
between top and base plates.
The force sensor contains three pairs of quartz plates, of
which one is sensitive to pressure in the z direction and the
two others to shear forces in the x and y directions. Mea-
surement takes place practically without displacement.
The force introduced is resolved into three orthogonal
components.

Positive or negative charges occur at the connections
depending on the direction of the force. Negative charges
produce positive voltages at the output of the charge am-
plifier and vice versa.
