Abstract
СПОСОБ ИЗМЕРЕНИЯ И АНАЛИЗА ГАЗОВОЗДУШНЫХ СМЕСЕЙ, при котором газовоздушный поток, содержащий пробный газ, пропускают через рабочую камеру, через которую проходит промодулированное излучение, и по CffTL Рмнрт.ст. сигналу приемника излучени фиксируют концентрацию пробного газа, отличающийс тем, что, с целью повышени производительности и точности, в рабочей камере калиброванного объема создают посто нное разрежение, например 20Р Мм рт.ст. подают анализируемый газовоздушный поток до достижени заданной концентрации пробного газа, равного концентрации пробного газа в провер емом объекте, измер ют врем создани концентрации пробного газа в рабочей камере и давление в момент достижени в рабочей камере этой концентрации измерительно-алогическим комп (Л лексом и по его сигналу фиксируют величину утечки в единицах газовоздушного потока.METHOD OF MEASURING AND ANALYSIS OF GAS-AIR MIXTURES, in which the gas-air flow containing the test gas is passed through the working chamber, through which modulated radiation passes, and according to CffTL Рмнрт.ст. The signal of the radiation receiver records the concentration of the sample gas, characterized in that, in order to increase productivity and accuracy, a constant vacuum is created in the working chamber of a calibrated volume, for example, 20 Mmm Hg. The analyzed gas-air flow is supplied until a predetermined concentration of the test gas is reached, equal to the concentration of the test gas in the object under test, the time at which the concentration of the test gas in the working chamber is created and the pressure at the time the concentration-measuring complex in the working chamber ( The signal is recorded for leakage in units of gas-air flow.
