Abstract
An electrolytic tilt sensor is disclosed which comprises a containment envelope having a metallic container and a header, the envelope defining a chamber and having at least one pair of apertures, an electrolytic solution partially filling the chamber, and at least one pair of electrodes, each electrode including an electrically active, transverse portion positioned within the chamber in a general horizontal alignment with one another defining a tilt axis, and a lead portion extending to the exterior of the envelope through the respective aperture. The tilt sensor may further include a sealing material disposed in each aperture of the providing a substantial fluid-tight seal about the respective electrode.

An electrolytic tilt sensor, comprising:
- a containment envelope including a header and a metallic container having a top portion and a side portion depending from the top portion, the envelope defining a chamber and having at least one pair of apertures formed there through;
- an electrolytic solution at least partially filling the chamber;
- and
- at least one pair of electrodes, each electrode including an electrically active, transverse portion positioned within the chamber in a general parallel relation with inner surface of the top portion of the metallic container, and a lead portion extending to the exterior of the envelope through a respective aperture of the at least one pair of apertures, said transverse portions of said pair of electrodes being in general alignment to define at least one tilt axis.
A method of producing a header assembly for use with an electrolytic tilt sensor, comprising the steps of:
- providing a plurality of electrodes with bent configurations, a header having a plurality of apertures for receiving the plurality of electrodes, and a mass of glass beads;
- placing the glass beads adjacent the bent portions of the plurality of electrodes and applying heat until the glass beads form a glass-to-metal seal;
- inserting each of the electrodes into a respective aperture of the plurality of apertures of the header;
- heating the header and electrodes to cause the beaded glass to melt to a glass-to-metal seal between the header and the plurality of glass beaded electrodes.
