Abstract
Изобретение относитс к измеритель ной технике. Цель изобретени - повышение точности за счет одновременного анализа нескольких спектральных составл ющих . Два идентичных измерительных канала 1, содержащих вибродатчик 2 и усилитель 3, след щий фильтр 4 и АЦП 5 воспринимают и преобразуют входные сигналы, которые затем поступают на блоки 10 измерени амплитуд совместно с преобразованными сигналами с задатчика б оборотов. После вычислени о блоке 11 вычислени частотных характеристик результат поступает в блок 13 пам ти. 5 ил.The invention relates to measuring technique. The purpose of the invention is to increase accuracy by simultaneously analyzing several spectral components. Two identical measuring channels 1, comprising a vibration sensor 2 and an amplifier 3, a servo filter 4, and an ADC 5, receive and convert input signals, which are then transmitted to the amplitude measuring units 10 together with the converted signals from the speed controller. After calculating about the frequency response calculating unit 11, the result enters the memory unit 13. 5 ill.
