Abstract

Aparato de control y medidas eléctricas, caracterizado porque comprende un generador de señales que proporciona una primera señal eléctrica a una frecuencia primera en respuesta a los cambios experimentales en dicha primera caracteristica, caracterizado por un modulador para modular la referida primera señal eléctrica a una segunda frecuencia, un circuito para comparar dicha primera señal eléctrica modulada con una señal eléctrica de referencia a dicha primera frecuencia y un mecanismo regulador que corresponde al componente modulador de la citada primera señal eléctrica modulada para regular dicha señal eléctrica de referencia con el fin de proporcionar una sensibilidad prácticamente mínima en la salida de dicho circuito de comparación a las variaciones en el elemento de la primera frecuencia de al referida primera señal eléctrica modulada que resulta de los cambios en una segunda caracteristica del citado objeto con lo que proporciona una salida que se determina por la primera caracteristica referida y que es prácticamente independiente de los cambios en dicha segunda caracteristica.
