  • Patent number: 4109312
    Abstract: Analog signals representing the unbalance of a rotor in one or more planes extending perpendicularly and across the longitudinal rotational axis of said rotor, are first adapted prior to an analog to digital conversion. The adaptation takes place in response to at least one adaptation value, which is characteristic for the balancing, such as an attenuation, a sensitivity control, an rpm or measuring range selection and the like. The adapted signal is then combined with a reference signal having a frequency corresponding to the rpm of the rotor. The combined signal is subjected to an analog to digital conversion and then digitally displayed. The circuit arrangement for the performance of the signal adaptation, signal combination and signal display includes adaptation circuit means which are responsive to said adaptation value or values. The adaptation circuit means is connected to receive the unbalance information with the correct sign (+ or -).
