Abstract
An electrolytic toroidal tilt sensing device for electrical coupling to a measuring circuit, wherein the measuring circuit is responsive to the device and adapted to provide an output signal indicative of the tilting and direction of tilting associated with the device, includes: an electrolytic fluid; a housing body having a channel formed therein for containing the electrolytic fluid, the housing body serving as a common electrode when coupled to the measuring circuit; and a cover plate having two working electrodes with at least one electrode serving as a working electrode when coupled to an appropriate measuring circuit, the cover plate being to hermetically fitted in the channel of the housing body such that the cover plate and the housing body form a chamber wherein at least one electrode is at least partially immersed in the electrolytic fluid contained within the chamber. Accordingly, when coupled to the measuring circuit, the device and, in particular, the electrolytic fluid's relationship to the electrodes exhibits at least one electrical property (e.g., impedance, conductance, capacitance, on/off condition, etc.) and a change therein when the device is tilted, the measuring circuit measuring such at least one electrical property and change therein through connection to the working electrode and the common electrode of the device and generating the output signal in response thereto.
