Description

Изобретение относитс  к способам проверки приборов, примен емых дл  аналитического измерени  состава и концентрации газов. Известные способы проверки исправност пламенно-ионизационных приборов дл  газового анализа, заключающиес  в измерении контрольного сигнала, пропущенного через основные тракты прибора, и сравнении этого сигнала с уставкой, не обеспечивают непрерьшного автоматического процесса проверки. С целью устранени  указанного недостат ка, согласно предложенному способу проверки , в качестве контрольного сигнала используют ионизационный ток детекторов, а в качестве уставки принимают фоновый ток. На чертеже показана схема устройства, например газоанализатора, исправность которого может быть проверена предложенным способом. Газоанализатор содержит пламенно-ионизационную камеру (детектор) 1 и усилител I посто нного тока 2. В камере размешены коллекторный электрод 3 и пламенна  горелка 4, выполн юща  роль аторо1хэ элект рода . Каналы 5 и 6 служат дл  подвода к горелке 4 водорода и анализируемого газа, канал 7 - дл  подвода воздуха, поддерживаю}цего горение, канал 8 - дл  сброса продуктов горени . В камере 1 размещена спираль 9, предназначенна  дл  зажигани  водорода. Усилитель посто нного тока 2 содержит высокоомный измерительный резистор 1О, автогенераторный преобразователь 11 с параметрическим модул тором 12, измерительный демодул тор 13 с индикатором 14 и демодул тор 15 цепи сигна;шза1ши исправности, нагруженный на электромагнитное реле 16 с.,контактной группой 17. Потенциометр 18 йбдключен к клемме 19 и служит дл  установки порога возбуждени  усилител  2, Газоанализатор работает следующим образом .The invention relates to methods for testing instruments used for analytical measurement of the composition and concentration of gases. The known methods for checking the serviceability of flame ionization gas analysis instruments, which consist in measuring the control signal passed through the main paths of the instrument and comparing this signal with the setpoint, do not provide a continuous automatic verification process. In order to eliminate this drawback, according to the proposed verification method, the ionization current of the detectors is used as a control signal, and the background current is taken as the setting. The drawing shows a diagram of the device, such as a gas analyzer, the health of which can be checked by the proposed method. The gas analyzer contains a flame ionization chamber (detector) 1 and an amplifier I with a direct current 2. A collector electrode 3 and a flame burner 4, acting as an atorome of the elec- trode, are placed in the chamber. Channels 5 and 6 serve to supply hydrogen and the analyzed gas to the burner 4, channel 7 - to supply air, support its combustion, channel 8 - to discharge the combustion products. In the chamber 1 is placed the spiral 9, designed to ignite hydrogen. The DC amplifier 2 contains a high-resistance measuring resistor 1O, an auto-oscillator converter 11 with a parametric modulator 12, a measuring demodulator 13 with an indicator 14, and a demodulator 15 of the signal circuit; 18dcc is connected to terminal 19 and serves to set the excitation threshold of amplifier 2. The gas analyzer operates as follows.
