Structure and principle of operation
The CLP force washer is based on the piezoelectric principle.
Compressive forces are transmitted to measuring elements that are sensitive to
force via the upper and lower force application surfaces. 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 only requires minimal displace
ment, so the stiffness of the transducer is therefore exceptionally high. The re
sulting high resonance frequencies make piezoelectric force transducers pre
destined for dynamic applications.
The force washer is hermetically welded and the coaxial cable is permanently
connected to the sensor. Compressive force generates a negative electrical
charge.
