The bending bar in SE 110.58 can be mounted vertically (standing or hanging) or horizontally into the frame SE 112. By varying the free clamping length or moving additional weights, the natural frequency of the bar is changed. The bar is deflected manually to start damped vibrations. A non-contact position sensor measures the corresponding amplitudes. The additionally required sensor supply module TM 151 processes the signal for its display on an oscilloscope (not supplied).
