Abstract

Una tarjeta de circuito de detección de nivel que caracteriza al menos un procesador y al menos una memoria que incluye un código de programa de computadora, en donde al menos una memoria y un código de programa de computadora son configurados, al menos con el procesador, para provocar que el aparato al menos: responda a una señal que contiene información relacionada con la conductividad eléctrica de material provocando un estímulo a una placa de detección que corresponde con una placa positiva de un capacitar directamente conectado con una entrada de un comparador que forma parte de un oscilador de frecuencia variable; y determine la respuesta proporcional que contiene la información acerca del material que provoca el estímulo a la placa de detección en función, al menos en forma parcial, de la señal recibida. El circuito de detección de nivel podría ser utilizado como un medio para encender o apagar la bomba en función del nivel detectado de fluido.
