Abstract
An electrolytic tilt sensor and a method of assembling the tilt sensor. The tilt sensor includes a metallic envelope comprising a metal container and a metal header welded to the enclosure, hermetically sealing the envelope. The envelope defines a chamber that contains an electrolytic solution and a plurality of electrodes. The electrodes extending through the header from outside of the envelope into the chamber. Each electrode is located in a separate aperture within the header and is insulated from the envelope by an insulator located between the electrode and the header. The method of assembling the tilt sensor includes the steps of placing the electrolytic solution into the container through an opening, engaging the header with the opening and welding the container and header to one another to hermetically seal the envelope.
