Tips regarding piezoelectric measurement technology

Piezoelectric force sensors offer advantages with regards to their use, above
all, in an industrial environment. These sensors are extraordinarily compact
and offer extremely high overload capacity when the measurement chain is
correctly laid out, evidencing negligible displacement. This results in high
rigidity and therefore excellent dynamic properties.
In order to ensure maximum measurement accuracy with high operating
safety, some information should be taken into account.

Functionality of piezoelectric sensors

A piezoelectric force sensor consists of a single crystal sensor elements and
components used for force application.
Working principle of a piezoelectric transducer
Forces acting on the crystal make charges move. The separation of the
charge centers of gravity is proportional to the applied force. The sum of the
shifted charges can be measured on the crystal surfaces.
