Force

Multicomponent Force Plate

Portable – for Applications in Biomechanics, Fz 0 ... 10 kN

Type 9286B...

Portable multicomponent force plate with aluminum top plate

for measuring ground reaction forces, moments and the center

of pressure in biomechanics.

• Excellent accuracy of center of pressure (COP)

• Very wide measuring range

• Easy mounting

• Flexible, mobile application

• Threshold Fz <250 mN

Description

Rather than conventional frame mounted force plates, the

multicomponent force plate Type 9286B... can simply be used

on any flat surface. This drastically cuts installation costs. The

plate's low overall height of just 35 mm and weight of under

18 kg allows flexible, portable use.

The piezoelectric 3-component force sensors have very low

crosstalk values and in conjunction with the special design

principle ensure excellent accuracy of the center of pressure.

Application

This force plate is designed specifically for use in gait and bal-

ance analyses. The Type 9286BA has a built-in charge amplifier

compatible with all of the common motion analysis systems.

Despite the very wide measuring range (0 ... 10 kN), this force

plate offers excellent accuracy and linearity over the entire

spectrum of applications (4 measuring ranges) and guarantees

overload protection up to 12 kN.
