This circuit was originally designed
to measure the volume of fluid inside a medical
syringe. As designed
, it produces a zero to 5 volt output, corresponding
to a capacitance change of about 10 picofarads. With a digital voltmeter, at
its output, it can resolve a capacitance change of 0.002 picofarads or 2
femtofarads. |
