摘要
The disclosure relates to a position- and/or vibration or accelerometer (1) for detection of low-frequency oscillation phenomena or deviations from imaginary stationary states. A singular inertia mass (12) is elastically and damped suspended in relation to a fixed body (6) so that its movement in relation to the fixed body, because of outer excitation thanks to its inertia relative to the fixed body, it may be considered as a local point mass with the point of gravity in any optional zero point in a coordinate system. Hereby, the movement of the mass (12) in one direction is standardised sensible in that, when the element because of its suspension is displaced from a position of rest and moves in a direction towards one induction element (7) and, to a corresponding degree away from another, opposing induction element, it gives rise to a phase shift and an induction change in the output signal from a differential measurement bridge which is supplied with a carrier frequency.
