<p>A method of and apparatus for scale factor compensation for piezo-electric rate sensors (8). Means (32) being provided for maintaining the magnitude of vibration at the primary pick-off point (Pp) substantially constant so as to enable one of the variables of a vibrating structure ( beta ) - the piezo-electric change coefficient to be determined and thereby enable the scale factor of the sensor (8) to be determined in order to enable correction of the sensor output to be made by a scale factor control unit (46) in order to ensure that the output therefrom more accurately reflects the true timing rate of the sensor. This enables such sensors to be employed in applications requiring a higher degree of accuracy than they were previously able to provide. <IMAGE></p> |
