Abstract
A dual range accelerometer includes a mass 10 supported on a cantilevered beam 12, there being stops 70, 71 such that for low accelerations the beam acts as a cantilever and for high accelerations, one of the stops causes the beam to flex as a beam supported at both ends. Surface acoustic wave devices 17, 46 provide a signal having a frequency which is a function of strain in the beam 12, thereby to detect accelerations in two different ranges.
