Kind Code:
B1
Abstract:
A compensating arrangement acts on the mass and is connected to the input of the integral transfer unit of a gravimeter system. The measuring indicator is connected to the output of the integral transfer unit via the compensating arrangement and a low pass filter whereby a signal proportional to the position of the mass is transferred to the compensating arrangement in a manner which compensates for the measuring force in the sense of a negative feedback thereby suppressing the short period accelerating forces acting on the gravimeter system and preventing such accelerating forces from affecting the indication of the measuring indicator.
