1. In a toroidal accelerometer including a housing, a plurality of electrode means disposed within said housing, electrolytic fluid means at least partially immersing each of said electrode means and amplifier means having an input coupled to the electrode means for providing at the output thereof a signal indicative of the tilt of the accelerometer about a reference axis, said plurality of electrode means including an electrode means totally immersed in said electrolytic fluid and coupled to the output of said amplifier means for temperature compensating said accelerometer;

  • apparatus for preventing polarization of the electrolytic fluid means without affecting the tilt signal comprising;

    circuit means having an input coupled to said amplifier means for detecting any d.c. voltage components developed in said amplifier means and, in response thereto, for coupling a compensating signal to an input of said amplifier means until the d.c. voltage is substantially eliminated.
