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

摘要

The invention concerns a temperature-compensated accelerator measurement using two vibrating resonators whereof the frequencies (f₁, f₂) are measured, then used for determining ( 18, 19 ) the most probable temperature value (T) based on the sum f₁+f₂ and on a pre-established correlation ( 14 ) between the temperature and the sum f₁+f₂ and finally based on the determination ( 20 ) of the amount f₁-f₂ of the weighted temperature value, calculating ( 21 ) the temperature compensated value of the acceleration (gamma).
