Abstract
A method for manufacturing an electrolytic tilt sensor comprises: a) forming sensing electrodes on a generally planar surface of a dielectric substrate; b) forming a reference electrode on the surface; c) mounting a housing to the substrate so that the sensing electrodes and the reference electrode are contiguous to a volume defined between the housing and the substrate; d) forming a fluid tight seal between the housing and the substrate; e) injecting an electrolytic fluid into the volume; f) sealing the electrolytic fluid in the volume; and g) forming an electrical circuit on the substrate for generating an output signal representing the angle of the dielectric substrate with respect to a gravitational field, wherein the electrical circuit includes an oscillator mounted on the surface.
