Title
(EN) ELECTRIC SIGNAL EMITTER WITH HALL EFFECT GENERATOR
(FR) TRANSMETTEUR ELECTRIQUE DE SIGNAUX AVEC GENERATEUR A EFFET HALL
Abstract
(EN)
Electric signal emitter with Hall generator (18), intended to provide control signals. The signal emitter further comprises an amplifier circuit (21) and a load resistance (29) connected to the output. The Hall effect generator (18), the amplifier circuit (21) and the load resistance (29) are connected to a supply voltage by means of a supply and signal circuit (22) with an ammeter resistance (23). Parallel to the ammeter resistance (23) there is provided a threshold value circuit (26) which is inverted by a voltage drop at the ammeter resistance (23) when the load resistance (29) is energized. The signal emitter may be used as a rotation speed indicator, as a dead point indicator or amongst other things as an ignition marking indicator for internal combustion engines.

Transmetteur éléctrique de signaux avec générateur à effet Hall (18), servant à produire des signaux de commande. Le transmetteur de signaux comporte en outre un circuit amplificateur (21) et une résistance de charge (29) raccordée vers la sortie. Le générateur à effet Hall (18), le circuit amplificateur (21) et la résistance de charge (29) sont raccordés à une tension d'alimentation par une ligne d'alimentation et de signaux (22) avec une résistance d'ampèremètre (23). Parallèlement à la résistance d'ampèremètre (23) se trouve un circuit de valeur seuil (26) qui est inversé par la chute de tension à la résistance d'ampèremètre (23) lorsque la résistance de charge (29) est mise sous tension. Le transmetteur de signaux peut être utilisé comme indicateur de la vitesse de rotation, indicateur de point mort ou, entre autres, comme indicateur de repère d'allumage pour des moteurs à combustion interne.
