Title (EN) PULSE GENERATOR
(FR) GENERATEUR D'IMPULSIONS
Abstract:
(EN) When generating signal changes in connection with the determination of the amount of fuel dispensed from a fuel pump unit, a periodic analog signal having a first frequency is generated, which corresponds to a fuel volume flow in the pump unit. The amplitude of the analog signal is detected and then signal changes having a second frequency are emitted, which is dependent on and higher than the first frequency. In an apparatus, the analog signal is generated by a frequency generator (31). A pulse-generating device (40) comprising at least one analog sensor (41, 42) and at least one unit (45) for signal-processing is arranged to detect the analog signal and to generate signal changes having a second higher frequency.
(FR) La génération de modifications de signal à la détermination de la quantité de carburant distribué par une pompe à carburant a pour effet la génération d'un signal analogique périodique présentant une première fréquence et correspondant à un débit volumétrique de la pompe. L'amplitude du signal analogique est détectée, puis sont émises des modifications de signal présentant une deuxième fréquence dépendante de la première fréquence et supérieure à celle-ci. Dans un dispositif, le signal analogique est généré par un générateur de fréquence (31). Un générateur d'impulsions (40) composé d'au moins un capteur analogique (41, 42) et d'au moins une unité (45) de traitement de signaux, est conçu pour détecter le signal analogique et pour générer des modifications de signal présentant une deuxième fréquence supérieure.
