title: Differential capacitance sensor as position detector for a magnetic suspension densimeter.
abstract: A differential capacitance sensor has been used in the servosystem of a magnetic suspension densimeter to detect the position of a magnetic buoy. This type of sensor has not previously been used in this application. Its design, performance, and advantages are described.
