Description

Multicomponent force plate Type 9285BA consists of a base frame on which four piezoelectric 3-component force sensors under a high preload are mounted. A 600x400 mm triple-layer composite glass plate is mounted on these sensors. The very low crosstalk values of the sensors in conjunction with the spe- cial design principle ensure very good accuracy of the center of pressure. Type 9285BA has a built-in charge amplifier compat- ible with all of the common motion analysis systems. Application This force plate is designed for special gait and balance analysis applications. The glass plate allows simultaneous force meas- urement and photographic or cinematographic recording of the contact surface from below. Despite the wide measuring range (0 ... 10 kN), this force plate offers excellent accuracy and linearity across the entire spectrum of applications and guarantees overload protection up to 12 kN. A larger force plate with external dimensions of 900x600 mm is available on request.
