Abstract

Una disposición para uso en un medidor de servicios incluye un sensor y un circuito de procesamiento soportados por una base del medidor, y un elemento magnético transportado por la cubierta del medidor, en el cual la cubierta está montada de forma desmontable a la base. El sensor incluye al menos dos elementos magnetizables, tales como inductores, que se magnetizan en polaridades opuestas cuando el medidor está cerrado y operable. Los elementos magnetizables están posicionados muy cerca de forma que la cubierta es removida y el elemento magnético pasa los elementos para ocasionar que los elementos magnéticos asuman la misma polaridad. El circuito de procesamiento continuamente obtiene los elementos magnetizables para evaluar sus respectivas polaridades y está configurado para emitir una indicación de manipulación cuando las polaridades detectadas son las mismas.
