Abstract
A bridge-type capacitance transducer is disclosed. The transducer utilizes a coaxially mounted circular stator and circular rotor to form the capacitance bridge. An excitation voltage is applied to the bridge. The output voltage of the bridge is conditioned by synchronous detection so as to yield a signal proportional to the degree of rotation of the rotor.
