Structure and Principle of Operation

The CLP force washer is based on the piezoelectric principle.
Compressive forces are transmitted via the upper and lower force application
surfaces to measuring elements that are sensitive to force. These separate
the electrical charges in proportion to the applied force. A charge amplifier can
then convert these electrical charges to an analog voltage signal.

The piezoelectric principle of measurement requires only minimum
displacement. The transducer therefore features unusually high stiffness. Due
to the resulting high resonance frequencies, piezoelectric force transducers
are ideally suited for dynamic applications.
The force washer is hermetically welded and the coaxial cable is permanently
connected with the sensor. Compressive force generates a negative electrical
charge.
