FIELD: measuring equipment engineering.
SUBSTANCE: method includes use of constant voltage signal as information signal, which is scaled, inverted and than added to bearing voltage signal, value of which is determined during synchronous rotation, received total is amplified until it is useable for measurement, than sliding of asynchronous engine is measured on basis of measured value.
EFFECT: higher interference resistance, higher precision, shorter time delay, possible automated process.
