Automatic pseudokeyphasor generator
First Claim
1. In apparatus for analyzing the vibratory behavior of a rotating machine in response to signals representing vibrations occurring in the machine, which apparatus includes:
- a controllable signal generator connected to receive an input signal representing the rate of rotation of the machine and to produce an output signal representing a rate of rotation bearing a selected relation to the rate of rotation represented by the input signal, the generator being responsive to digital signals which set the value of the selected relation; and
a signal analyzing device connected to receive the signals representing vibrations and the output signal from the signal generator for processing the signals representing vibrations as a function of the machine rotation rate represented by the output signal from the signal generator, the improvement comprising;
digital signal supply means providing first digital signals representing the value of the selected relation; and
electrically controlled signal generating means connected between said digital signal supply means and said controllable signal generator for supplying to said controllable signal generator second digital signals which correspond to the first digital signals and which act to set the value of the selected relation

Abstract
A pseudokeyphasor signal control unit incorporated into apparatus for analyzing the vibratory behavior of a rotating machine in response to signals representing vibrations occuring in the machine, which apparatus includes: a controllable signal generator connected to receive an input signal representing the rate of rotation of the machine and to produce an output signal representing a rate of rotation bearing a selected relation to the rate of rotation represented by the input signal, the generator being responsive to digital signals which set the value of the selected relation; and a signal analyzing device connected to receive the signals representing vibrations and the output signal from the signal generator for processing the signals representing vibrations as a function of the machine rotation rate represented by the output signal from the signal generator. The unit is composed of a digital signal supply member providing first digital signals representing the value of the selected relation; and an electrically controlled signal supply member connected between the digital signal supply member and the controllable signal generator for supplying to the controllable signal generator second digital signals which correspond to the first digital signals and which act to set the value of the selected relation.
