Capacitive Sensors with Pre-calculable Capacitance
Abstract
The advantages of capacitance techniques formeasurement are well known and can be further enhanced
by application of the design methods based on possibility to
calculate their capacitance solely from electrode dimensions.
The analytical calculation of capacitance is limited only to
capacitors having cylindrical geometry of electrodes.
Nevertheless by conformal mapping the majority of
capacitive sensors can be designed. In this article besides the
basic theory an example of sensor for measurement the
angle of rotation is presented.
