ВЕЛИЧИН 5 периода колебаний в измерительный сигнал, где формируетс  сигнал, например , в виде импульсной последовательности , число импульсов которой пропорционально периоду сигнала струнного преобразовател . Измерительный сигнал с выходой преобразова телей 4 и 5 поступает в блок, б делени , где производитс  вычисление отношени  периодов колебаний с выходов струнного преобразовател . Использование в данном устройстве обработки выходного сигнала в режиме отношени  периодов позвол ет существенно снизить динамическую, ошибку измерени  за счет сокращений времени измерени . Формула изобретени  Устройство дл  измерени  механических величин, содержащее симметричный дифференциальный струнный преобразователь и два усилител , подключенные входгми к выходам струнного преобразовател , отличающеес  тем, что, с целью повышени  динамической точности измерени , оно снабжено двум  преобразовател ми периода колебани  в измерительный сигнал, ходы которых подключены соответственно к выходам первого и второго усилителей , и блоком делени , входы которого подключены к выходам преобразователей периода колебаний в измеритель ный сигнал-.

VALUE 5 of the oscillation period in the measurement signal, where the signal is formed, for example, in the form of a pulse sequence, the number of pulses of which is proportional to the signal period of the string converter. The measurement signal from the output of converters 4 and 5 enters the block, b division, where the calculation of the ratio of the oscillation periods from the outputs of the string converter is performed. The use in this device of processing the output signal in the period ratio mode makes it possible to significantly reduce the dynamic, measurement error due to the reduction in the measurement time. An apparatus for measuring mechanical quantities, comprising a symmetric differential string converter and two amplifiers connected in input to the outputs of a string converter, characterized in that, in order to increase the dynamic accuracy of the measurement, it is equipped with two transducers of the oscillation period into the measuring signal, the strokes of which are connected respectively to the outputs of the first and second amplifiers, and the division unit, the inputs of which are connected to the outputs of the transducers of the oscillation period in measuring signal-.
