3. General Description
SlimLine piezoelectric force sensors feature an extremely
compact design. The force to be measured is transferred to
the quartz sensor elements via the cover plate and base
plate of the tightly welded steel housing. The quartz ele-
ments produce an electric charge proportional to the me-
chanical load. A charge amplifier generates an electric volt-
age from this charge. These signals are displayed, recorded
or processed in the familiar way.
Thanks to the extremely high resolution of quartz it is pos-
sible to measure a change in force of the order of 1 N un-
der a preload of several tons.
The compact design and the relatively small dimensions al-
low flexible application and easy mounting.
Sensitivity (charge per unit force) is a constant of quartz as
a material. The associated threshold is virtually the same
for all SlimLine sensors of different sizes.
This has three unique advantages:

High level of overload protection, very small forces can
be measured with one sensor with a large measuring
range

High rigidity; a sensor with a larger measuring range
undergoes less deformation

Several sensors can be electrically connected in parallel
to a single charge amplifier. The output signal is then
the sum of all of acting forces
SlimLine quartz force links are supplied calibrated (in rela-
tion to the compression force range only). This ensures
they are easy to mount and immediately ready for meas-
urement.
