Abstract
Изобретение относитс к измерительной технике. Цель изобретени - повышение точности измерени и расширение номенклатуры измер емых изделий путем изменени цены делени измерител устройства. Измер емый предмет проходит перпендикул рно плоскости осей оптических пар, расположенных на П-образной раме 1. При этом происходит перекрытие светового потока некоторого количества излучателей 2, а следовательно, на выходе такого же количества фотоприемников 3 формируетс сигнал "о". В результате на выходе аналогового мультиплексора 10 согласно коду опроса, сформированного счетчиком 8, формируетс сигнал, который поступит на индикатор 12 /цифроаналоговый преобразователь/, на выходе которого формируетс сигнал, пропорциональный размеру предмета, который затем поступает на усилитель 5, выход которого вл етс выходом устройства. Если габариты измер емого предмета малы или не устраивает точность измерени , то П-образную раму 1 наклон ют на угол α. Величина этого угла α преобразуетс в напр жение преобразователем 4 угол - напр жение, который вырабатывает необходимое напр жени дл управлени коэффициентом усилени усилител 5, тем самым мен цену делени измерител устройства. 3 ил.This invention relates to a measurement technique. The purpose of the invention is to improve the accuracy of measurement and the expansion of the range of measured products by changing the dividing price of the meter device. The measured object passes perpendicular to the plane of the axes of the optical pairs located on the U-shaped frame 1. At the same time, a luminous flux of a certain number of emitters 2 is overlapped, and therefore, an "o" signal is generated at the output of the same number of photodetectors 3. As a result, the output of the analog multiplexer 10 according to the interrogation code formed by the counter 8 generates a signal that goes to the indicator 12 / digital-to-analog converter /, the output of which produces a signal proportional to the size of the object, which then goes to the amplifier 5, the output of which is output devices. If the dimensions of the object to be measured are small or not satisfied with the measurement accuracy, then the U-shaped frame 1 is inclined by an angle α. The magnitude of this angle α is converted to voltage by converter 4 angle - voltage that produces the necessary voltage to control the gain of amplifier 5, thereby changing the dividing price of the meter device. 3 il.
