Abstract

In a vibratory angular rate sensor of the kind comprising a hollow cylinder (3) secured at one end to a base (5) and free at the other end and transducers (9) on the cylinder (3) for exciting and detecting radial vibrations in the cylinder wall, the transducers (9) are positioned near the end of the cylinder (3) secured to the base (5), and the base (5) rigidly fixes the adjacent end of the cylinder (3) thereby to maximise coupling of the transducers (9) to vibrations produced in the cylinder (3) in operation of the sensor. <IMAGE>
