Description

The multicomponent force plate Type 9287C... consists of a 900x600 mm aluminum sandwich top plate of advanced, lightweight construction and four built-in piezoelectric 3-com- ponent force sensors. Thus it is extremely rigid overall, and al- lows measurements over a very wide useful frequency range. Thanks to the special properties of the piezoelectric sensors, the force plate is highly sensitive and can simultaneously meas- ure very dynamic phenomena involved in a wide range of applications. Application This force plate is designed specifically for use in basic research and sport. Its large size, wide measuring range and high rigidity allow it to be employed for a very wide spectrum of measur - ing tasks and application sectors. Despite the very generous measuring range of -10 ... 20 kN, it offers excellent accuracy and linearity and even under a large preload allows precise measurement of minute forces. In all these situations the force plate can be mounted in any position without affecting the measurement result in any way. The Type 9287CA has an built-in charge amplifier compatible with all of the common motion analysis systems.
