ＤＦＴ－１型肺通气量仪是一种电子自动化程度较高、接收灵敏度较强的自动化检测仪器。适用于体检及肺功能的检测。故障现象肺通气仪探头失灵分析检修由于该探头灵敏度较高，很小的气流就可以使转片旋转，其旋转的小孔使光电二极管分别为截止和导通。产生的信号经放大器放...
The DFT-1 Pulmonary Ventilator is an automated detection instrument with a high degree of electronic automation and strong reception sensitivity. Applicable to physical examination and lung function testing. Fault Phenomenon Failure of the lung ventilation probe Due to the high sensitivity of the probe, a small amount of air flow can rotate the rotor, and its rotating holes make the photodiodes turn off and on, respectively. The signal generated by the amplifier is placed...
