DEVICE FOR CONTROLLING AN EXCITATION SIGNAL FROM A RESONANT MECHANICAL OSCILLATING ELEMENT, MEASURING DEVICE, METHOD OF CONTROLLING THE EXCITATION SIGNAL, METHOD OF TAKING MEASUREMENTS, COMPUTER PROGRAM AND STORAGE DEVICE

摘要

The invention relates to a device for controlling an excitation signal from a resonant mechanical oscillating element (3) which is excited by said excitation signal (F). The inventive control device also comprises means for determining a phase difference (?) between a signal that is representative of the oscillation (Z) of the oscillating element and a feedback component (F2) and means for generating the feedback component (F2) which are configured such that the amplitude (GA) of said feedback component (F2) is a function of the aforementioned phase difference (?). The invention also relates to a measuring device, a method of controlling the excitation signal, a method of taking measurements, a computer program and a storage device.
