Product type
Force sensor type
A dynamometer is a force plate measuring forces and moments.
Multicomponent dynamometer
Preloaded sensor
Preloaded sensors are already calibrated and therefore ready-to-use. Non-preloaded sensors are smaller.

Metrological characteristics
Linearity
Linearity represents the maximum deviation/error between ideal and actual output signal characteristics in relation to the measurand in a specific measuring range. It is expressed in percentage of the range of measurement signal (Full Scale Output).

Trata-se de um dinamômetro de quatro componentes para medir um Mz binário e os três componentes ortogonais de uma força. O dinamômetro possui uma grande desvantagem e, consequentemente, uma frequência natural elevada. A sua elevada resolução permite medir as mais pequenas alterações dinâmicas em grandes forças e binárias.
