Abstract

1530358 Proximity detectors SOC ANON POUR L'EQUIPMENT ELECTRIQUE DES VEHICULES SEV MARCHAL 8 Dec 1976 [8 Dec 1975] 51263/76 Heading G1N A proximity detector comprises a Colpitts oscillator the coil 1 of which in use is mounted adjacent a toothed movable member e.g. a rotor 2. The transistor 5 of the oscillator has its emitter connected to its base through a diode 15 in series with a resistor 16 and a capacitor 17 is mounted in parellel with the "diode-resistor" connection. A diode 10 is provided for temperature compensation.
