ABSTRACT:
A digitizer for a gravity meter having a rotatable gradient readout dial and a null indicator, the digitizer comprising a shaft position sensor attached to the readout dial for providing a digital output signal representation of clockwise and counterclockwise rotation of the readout dial during nulling of said indicator, a microprocessor coupled to the shaft position sensor for receiving and storing the sensor digital output signal representation and means in the microprocessor for analyzing the stored digital output signals from the shaft position sensor and producing and storing a digitized output signal representing the gravity in the form of the average position of the readout dial on the gravity meter.
