ELEKTRISCHER SIGNALGEBER MIT EINEM HALLGENERATOR

摘要

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.
