An accelerometer has two proof masses each constrained from movement by a beam resonant force transducer. The proof mass-force transducer systems are mounted with the sensitive axes of the proof masses aligned and the force transducers arranged so that their resonant frequencies f1 and f2 vary oppositely with a change in acceleration. The acceleration is determined in accordance with the relation a=A1f1-A2f3+A0 or a=A1f12-A2f22+A0 where a is the acceleration and A1, A2 and A0 are calibration coefficients.
