ABSTRACT:
A sensor for measuring angular displacement of a small body comprising a sealed housing containing a differential transformer having at least two primary coils, one primary and two secondary coils, or two primary and two secondary coils, said coils being partially submerged in a ferromagnetic fluid. Upon application of an AC current to at least the primary coils of the differential transformer, the voltage across the circuit defined by the two primary or the two secondary coils is indicative of the angle of tilt of the sensor and the body to which it is attached.
