Antitheft warning apparatus for vehicles comprehending at least an operating central module MCF and a motion module MAS equipped with an electrolytic transducer, with a central electrode and two or more peripherical ones placed simmetrically respect to the central, and by an electronic circuit equipped with a rectifying and amplifying section SDA, a slope making section SFR and a comparing section SCO, being the peripherical electrodes supplied continuously by module MCF and being the output signal from the central electrode worked in section SDA, compared in section SCO with the output signal of section SFR, also operated by MCF, so that module MCF measures the time elapsed from the beginning of the slope to the moment in which said slope reaches the value of the output signal of the central electrode and compares it with the initial value of said time evaluated by module MCF in correspondence of the initial attitude of the vehicle, and can establish then if a change of attitude of the vehicle and therefore a warning state has occurred and operate therefore the warning, being the module MAS equipped with a container, which allow the operator to adjust the direction of the transducer so as at the beginning the electrolyte surface is orizontal and the peripherical electrodes directed according a wanted direction in relation to the type of vehicle. |
