The invention concerns a temperature-compensated accelerator measurement using two vibrating resonators whereof the frequencies (f, f) are measured, then used for determining () the most probable temperature value (T) based on the sum f+fand on a pre-established correlation () between the temperature and the sum f+fand finally based on the determination () of the amount f&#x2212;fof the weighted temperature value, calculating () the temperature compensated value of the acceleration (&#x3b3;).

Method for temperature-compensated accelerometer measurement, with at least a device comprising two vibrating resonators

The inertial sensor comprises at least one vibrating element having one end connected to a support element and an opposite end connected to a test mass which is hinged to the support element by at least two link elements and which includes a cavity in which the vibrating element and a portion of the support element adjacent to the vibrating element are received. The link elements are housed in the cavity surrounding a portion of the support element to which the link elements are connected.
