PROCESS AND DEVICE TO DIAGNOSE OBJECTS FUNCTIONING CYCLICALLY Russian patent published in 2001 - IPC

FIELD: measurement technology. SUBSTANCE: process is related to diagnostics of objects with repeating cycles of functioning, for instance, rotating objects. Process includes preliminary, main and finishing stages. Multiple averaging excludes random deviation from levels of amplitude in frequency zones creating basis of authenticity of diagnostics. Step-by-step comparison of next averaged levels of amplitude components of spectrum with renewed levels of current base signals in zones is foreseen. Process and device provide for proximate method with three gradations of diagnostics: surpassing of permissible normal and limitations, necessity of more thorough analysis of object and faultless functioning of device. EFFECT: reduced measurement time thanks to forced limitation of measurement process if there is no necessity for more accurate diagnostics. 7 cl, 1 dwg
