Abstract
Изобретение относитс к контрольно-измерительной технике, в частности к оптическим способам контрол дисперсного состава взвешенных частиц, и может найти применение в химической промышленности дл определени степени очистки жидких и газообразных технологических сред. Целью изобретени вл етс повышение точности за счет увеличени отношени сигнал/шум. Сущность изобретени состоит в том, что одновременно регистрируют рассе нный и ослабленный частицей свет, и вычитают переменные составл ющие соответствующих сигналов от одних и тех же частиц в одни и те же моменты времени, причем о размерах частиц суд т по амплитуде разностных импульсов, а о концентрации частиц - по числу разностных импульсов. 1 ил.The invention relates to measuring instrumentation, in particular to optical methods for controlling the dispersed composition of suspended particles, and can be used in the chemical industry to determine the degree of purification of liquid and gaseous process media. The aim of the invention is to improve accuracy by increasing the signal-to-noise ratio. The essence of the invention is that the light scattered and attenuated by the particle is simultaneously recorded, and the variable components of the corresponding signals are subtracted from the same particles at the same time points, and the particle sizes are judged by the amplitude of the difference pulses, and particle concentrations — by the number of difference pulses. 1 il.

Устройство работает следуюш 1М образом .The device works in the following 1M way.
Анализируемую среду, прокачиваемую с посто нной скоростью через систему 3 прокачки, освещают при помощи источника 1 света и фокусирующего объектива 2. Свет, рассе нньй частицами , собираетс приемной системой 5 из ограниченного объема, размеры которого определ ют диафрагмой 11, и регистрируетс фотоприемником- 3. Прошедший через систему прок ачки световой поток собираетс приемной системой 4, при этом лучи, идущиеThe analyzed medium pumped at a constant speed through the pumping system 3 is illuminated with the help of a light source 1 and a focusing lens 2. The light scattered by particles is collected by a receiving system 5 of limited volume, the dimensions of which are determined by the diaphragm 11, and recorded by a photodetector. The luminous flux that has passed through the proc- essing system is collected by the receiving system 4, with the rays coming
