Abstract

A rotational sensor has a vibrating weight with two acceleration sensors mounted on it. The two acceleration sensors are designed to detect forces acting at a right angle to each other. The vibrating weight is set in vibration by means of driving devices, and rotation of the rotational sensor about two axes of rotation that are normal to each other is detected with the help of the acceleration sensors. The Coriolis forces in a plane are determined in this way.
