In a gravimeter, the gravity-responsive mass-and-spring system which responds to changes in gravity exhibits a dependence of its response upon changes in temperature. For compensating such temperature dependence, an electrically controllable force transmitter, preferably of the electromagnetic type, is connected with the mass of the gravimeter system to impose a corrective force thereupon. The force transmitter is controlled by an electric device which comprises temperature sensor means mounted in the housing which accommodates the gravimeter system. The sensor means operate to vary the corrective force in the sense required for minimizing or obviating the temperature dependence of the response characteristic.
