METHOD TO MEASURE TRANSVERSE VIBRATION AND ANGULAR VIBRATION, METHOD TO MEASURE TORSIONAL VIBRATION AND ROTORDYNAMIC MACHINE

摘要

FIELD: measurement equipment.SUBSTANCE: in approximate versions of realisation the surface of a rotary element is equipped with a reference phase mark and several additional marks. A contactless approach sensor detects passage of both the reference phase mark and additional marks as they pass via the detection zone. Both the reference phase signal and the reference vibration signal are generated, and these signals are used to calculate transverse and angular (and torsional, if necessary) vibration of rotary elements.EFFECT: improved measurement.19 cl, 7 dwg
