Piezoelectric dynamometer
13 July 2016
The stationary, multicomponent dynamometer from Kistler Instruments has been designed to measure forces and moments in all three axes produced during high performance cutting processes with high accuracy and signal quality for the precise analysis of drilling, cutting and grinding at high removal rates.
The compact piezoelectric dynamometer has an extremely robust structural design combined with a wide measuring range from a few Newtons to 30kN in all three directions making the Type 9139AA suitable for demanding applications where both low and high cutting forces are developed.
The patented design has integrated temperature compensation which eliminates the effect of heat generated during the cutting process to minimise signal drift. This ensures that forces generated by processes that create large amounts of heat may be measured with great accuracy.
