    Abstract: A gas detection system utilizing an ionic gas detector having an extended range of sensitivity adjustment obtained by signal and sample attenuation. Signal attenuation adjustment is obtained by use of a voltage divider in the detector output circuit. Sample attenuation is obtained by adjusting the ratio of sample and diluent gases with control valves and calibrated orifices. Both adjustments are made with a single sensitivity controller.

    Abstract translation: 一种利用离子气体检测器的气体检测系统,其具有通过信号和样品衰减获得的灵敏度调整范围的扩展。 通过在检测器输出电路中使用分压器来获得信号衰减调整。 样品衰减通过调节样品和稀释气体与控制阀和校准孔的比例来获得。 两个调整都是用一个灵敏度控制器进行的。
