Abstract

A piezo electric device for determining acceleration and angular velocity has at least three piezo-electric arms radially disposed on a rotatable shaft. As shown two dipoles 22 24 are mounted on a shaft 26. The arrangement overcomes disadvantages arising in the single dipole arrangement disclosed in U.S. Patent Specification 4197737. A demodulator circuit 28 is provided. <IMAGE>
