ABSTRACT:
The invention relates to a process and a device for the digital indication of the extent of unbalance of a part to be balanced in at least one plane when measuring its unbalance in balancing machines. An alternating voltage corresponding to the extent of unbalance is supplied to an integrator. A reference voltage is supplied to cancel out the output voltage of the integrator. While the integrator is being returned to zero, pulses are supplied to a counter which is thereby actuated to display the extent of the unbalance in digital form.
