Devices (1) are provided with sensor arrangements (2) comprising field generators (10) for generating magnetic fields and first/second/third field detectors (11,12,13) comprising first/second/third elements (R1-R4, S1-S4,T1-T4) for detecting first/second/third components of the magnetic fields in a plane and movable objects (14) for, in response to first/second/third accelerations of the movable objects (14) in first/second/third directions, changing the first/second/third components of the magnetic fields in the plane. The first (second, third) field detector (11,12,13) is more sensitive to the first (second, third) acceleration than to the other accelerations. Such devices (1) have a good sensitivity and a good linearity. The elements (R1-R4,S1-S4,T1-T4) form part of bridges. The first elements (R1-R4) surround the second and third elements (S1-S4,T1-T4), or vice versa. The first elements (R1-R4) may be in round or rectangular form and the second and third elements (S1-S4,T1-T4) may be in the form of sun beams leaving a sun.
