Abstract
A method for actively calculating and monitoring the oil debris monitor phase angle includes sensing a noise from an in-line oil debris monitor sensor in an oil flow path, generating a polar plot of an I and Q channel data from only the noise. Linear regression of noise is then utilized from the I and Q channel data for calculating a slope of regression form the linear regression and converting the slope to a phase angle.
Claims19
A method for actively calculating and monitoring oil debris monitor phase angle in an oil system, comprising:
- sensing a noise from an in-line oil debris monitor sensor in an oil flow path of the oil system;
- generating a polar plot of an I and Q channel data from only the noise;
- identifying a multiple of noise peaks in the polar plot;
- determining a linear regression of the noise peaks;
- calculating a slope of regression from the linear regression;
- and
- converting the slope to a phase angle.
