Abstract

A sensor for detecting a rotation rate of an object, including: a sensor element, which is designed to vibrate at an angle to the rotation axis of the rotation rate to be detected at an excitation frequency on a resetting element fastened in a spatially fixed manner to the object, such that the sensor element is deflected at a reaction frequency in a reaction direction at an angle to the rotation axis and at an angle to the vibration direction owing to the Coriolis force; and a measuring transducer, which is designed to detect the vibration in the reaction direction wherein the vibratable sensor element is formed in such a manner that a comparison of a temperature-dependent displacement of a frequency spacing between the excitation frequency and the reaction frequency and a temperature-dependent position of the sensor element on the object satisfies a predefined condition.
