Abstract:
A method for manufacturing an electrolytic tilt sensor, comprising the steps of:forming first and second sensing electrodes on a generally planar surface of a dielectric substrate; forming a reference electrode on said generally planar surface; wherein said first and second sensing electrodes are each shaped as a semi-circular arch and concentrically opposed about said reference electrode; mounting a housing to said dielectric substrate so that said first and second sensing electrodes and said reference electrode are contiguous to a volume defined between said housing and said dielectric substrate; forming a fluid tight seal between said housing and said dielectric substrate; injecting an electrolytic fluid into said volume; sealing said electrolytic fluid in said volume; and forming an electrical circuit on said dielectric substrate for generating an output signal representing an angular position of said dielectric substrate with respect to a gravitational field, wherein said electrical circuit includes an oscillator mounted on said planar surface.
