ABSTRACT:
The technique for replacing certain components in a linear accelerometer with an arrangement compatible with all of the other components making up the accelerometer is disclosed herein. The components that are replaced include a potentiometer and mechanical acceleration sensing means which cooperate with one another and which operate on a DC excitation voltage for producing an initial voltage dependent on both the acceleration sensed and the excitation voltage. The arrangement replacing these latter components include acceleration sensing means operating on the same DC excitation voltage for producing an initial voltage which is dependent on the acceleration but which is independent of the excitation voltage and means for adding a percentage of the excitation voltage to this latter voltage for providing a voltage which is dependent on both the acceleration sensed and the excitation voltage, thereby making the arrangement compatible with those components in the accelerometer which have not been replaced.
