A tamper alarm circuit for detecting a tampered condition of a utility meter is disclosed. The tamper alarm circuit has a transducer coupled to an amplification circuit which is coupled to a detection circuit, the detection circuit generating an alarm condition when the detection circuit determines that a voltage signal generated by the transducer and amplified by the amplification circuit has reached a predetermined threshold.
Cette invention se rapporte à un circuit d'alarme de falsification destiné à détecter un état de falsification d'un compteur d'énergie. Le circuit d'alarme de falsification est doté d'un transducteur couplé à un circuit d'amplification qui est couplé à un circuit de détection, le circuit de détection générant une condition d'alarme, lorsque le circuit de détection détermine qu'un signal de tension, généré par le transducteur et amplifié par le circuit d'amplification, a atteint un seuil prédéterminé.
