日本新宇宙电气公司最近研制成功一种利用不同气体其热导不同的原理制成的气体热传导式传感器,以及由传感器表面接触燃烧时所产生的温度变化而制的CO_2和CO检测回路,如图1和图2所示。这两种传感器的阻抗都很小,采用集 Japan’s new cosmic electric company recently developed a different use of different gas heat conduction of different principles made of gas heat conduction sensor, and by contact with the sensor surface combustion temperature changes produced CO_2 and CO detection circuit, as shown in Figure 1 and Figure 2. The impedance of these two sensors are small, using set
