ABSTRACT:
A toroidal accelerometer having a housing containing an electrolytic fluid at least partially immersing a plurality of electrodes disposed within said housing and an amplifier circuit coupled to the electrodes for providing an output signal indicative of the angle of tilt or rotation of the accelerometer about a reference axis. The accelerometer further includes a circuit connected across the amplifier to prevent polarization of the electrolytic fluid by detecting any d.c. voltage developed by the amplifier circuit and, in response thereto, coupling a compensating signal generated thereby to the amplifier until the d.c. voltage is substantially eliminated.
