ABSTRACT:
A proof mass for an accelerometer is electromagnetically constrained in three orthogonal directions. An array of filaments forms an elastic suspension for the proof mass to constrain it in the remaining degrees of freedom. The resulting instrument has the potential for low cost and high-accuracy operation over a wide temperature range without the use of temperature controls. An improved transition device provides a relatively simple, controllable and inexpensive means for temperature stabilizing the elastic suspension.
