Abstract

Sistema antifraude para detectar la aplicación de campos magnéticos no deseados a dispositivos sensibles. Previsto para detectar la aplicación de campos intensos, como los producidos por imanes, a dispositivos que puedan ser perturbados por dichos campos, como por ejemplo los contadores de agua, y concretamente para detectar un posible fraude mediante la aplicación de campos magnéticos en un dispositivo sensible (3), que puede corresponder a un contador de agua. El sistema comprende una etiqueta formada por un material magnéticamente duro (1) y un material magnéticamente blando (2), que se adhiere al propio dispositivo sensible (3), en combinación con un sistema de bobinas de excitación (5, 5') situadas sobre un soporte (4) de material no magnético, y unas bobinas de detección (6, 6') situadas bajo el aludido soporte (4), de manera que en combinación con la electrónica adecuada, permiten leer la etiqueta (1, 2) y determinar si se ha acercado un imán al dispositivo sensible (3).
