Kistler 9287C Series - Force Plate Model Versions; Force Plate Application Examples; Force Plate Functional Principle

General Description of the Instrument
3.2 Two Different Versions
The force plate 9287C... is available in two versions:
 Type 9287C with external 8 channel amplifier
(e.g. Type 9865…)
 Type 9287CA with built-in charge amplifier
3.3 Application Examples
 The force plate is particularly suitable to measure fast
actions and impact in sports but it can also be used for
a wide range of other applications
 Biomechanical investigations, e.g. recording the forces
exerted by the human foot when standing, walking or
running (gait analysis)
 Orthopaedic examinations
 Determining progress in rehabilitation, e.g. with pros-
thesis, after fractures etc.
 Analysis of high dynamic sports activities to optimize
training and for competition analysis (e.g. starting and
takeoff behaviour, performance measurement etc.)
 Coefficients of friction can be determined dynamically
and statically with the BioWare software system
3.4 Functional Principle
The force to be measured is introduced via a top plate and
distributed between four 3-component force sensors ar-
ranged between mounting base and top plate. Each of the
sensors has three pairs of quartz plates, one sensitive to
pressure in the z-direction and the other two to shear in
the x- and y-directions respectively. The measurement is
virtually without displacement. In these four force sensors
the force introduced is resolved into three components.
