振动式气体密度测定仪由于具有高使用率而获得了广泛的应用。这些仪器的线路图是一自振系统,其敏感元件是一实现振荡回路作用的机械振子。与振子振动速度的振幅成比例的初始转换器
Vibrating gas densitometers are widely used due to their high utilization. The circuit diagram of these instruments is a natural vibration system, the sensor is a mechanical oscillator to achieve the role of the oscillation circuit. The initial converter is proportional to the amplitude of the vibration speed of the vibrator
