Abstract

Устройството намира приложение при контрола върху веществата с оптически методи, предимно за анализ на оптическата плътност на отработени газове от автомобили. То е с повишена точност и се състои от корпус (1), в който на една ос (4) са разположени източник на светлина (2), измервателна камера (5) и фотоприемник (7). Към фотоприемника (7) са включени последователно свързани усилвател (8), логаритмичен преобразувател (9) и регистриращо устройство (10). Източникът на светлина (2) и фотоприемникът (7) са разположени в близост до челната стена на съответния глух канал (12 и 13), изработен в корпуса (1). Каналите (12 и 13) са свързани с камерата (5), а напречното им сечение е поне 8 пъти по-малко от напречното сечение на камерата (5). Дълбочината l на каналите (12 и 13) е не по-малка от 8 техни радиуса. 2 претенции, 2 фигури
