Abstract
The sensor comprises a body formed by first and second elements of which at least one has a cavity, the elements being sealed together to form a chamber. The chamber contains an electrically-conductive liquid which fills it almost completely so as to form a bubble. At least one main electrode and at least one pair of auxiliary electrodes extend into the chamber through the body and are accessible on the exterior thereof, so that any variation in the inclination of the body relative to at least one predetermined direction causes a movement of the bubble and a corresponding variation in the electrical resistance measurable between each auxiliary electrode and the main electrode. The electrodes are constituted by strips of electrically-conductive material deposited by screen printing on at least one of the said elements by thick film deposition method.
