    • The invention relates to measuring devices used in measuring angular velocity, and, more precisely, to vibrating micromechanical sensors of angular velocity. In the solution for a sensor of angular velocity according to the invention, a mass is suspended by means of spring structures having non-orthogonal primary and secondary axes such, that a test activation in phase with the primary motion is induced in a detection resonator, and the angular velocity to be measured is, by means of a phase detector, detected from the phase difference between the primary motion and the secondary motion. The structure of the sensor of angular velocity according to the invention enables reliable measuring with good performance, particularly in small vibrating micromechanical solutions for a sensor of angular velocity.
    • 本发明涉及用于测量角速度的测量装置,更确切地说,涉及角速度的振动微机械传感器。 在根据本发明的用于角速度传感器的解决方案中,通过具有非正交主轴和次轴的弹簧结构悬挂质量,使得在检测谐振器中感应与主运动相位的测试激活, 并且要测量的角速度通过相位检测器从主运动和次运动之间的相位差中检测出。 根据本发明的角速度传感器的结构能够以良好的性能进行可靠的测量,特别是在角速度传感器的小型振动微机械解决方案中。
