5、本实验是把气压的压力变化通过扩散硅压力传感器转化为电压的变化,微弱的电压信号经差动放大器放大后,用毫伏表观察电压的变化,并进行数据分析处理和人体血压的测量。 In this experiment, the pressure change of air pressure is transformed into the change of voltage through the diffusion silicon pressure sensor. After the weak voltage signal is amplified by the differential amplifier, the change of voltage is observed with a millivoltmeter, which will be used for data processing and blood pressure measurement.
