Abstract
Dispositivo medidor de nivel para líquidos, apto para detectar el descenso de dicho nivel por debajo de un nivel de umbral predeterminado, caracterizado por comprender: una sonda detectora (4) que lleva asociado un elemento calefactor eléctrico (5), activable selectivamente; dicha sonda (4) es ap.a para ser introducida, en el empleo, en dicho líquido (L), en tal disposición que el calor generado por el elemento calefactor (5) en el momento de su activación se disipe en el líquido (L) en grado diferenciado según cuál sea el nivel de dicho líquido (L), respectivamente encima o debajo de dicho nivel de umbral (L); un primer elemento sensor termoeléctrico (6) y un segundo elemento sensor termoeléctrico (7) para la detección de la temperatura del líquido (L), montados en dicha sonda (4) en tal disposición que dicho primer elemento sensor (6) sea capaz de detectar la temperatura alcanzada por el elemento calefactor (5) en el momento de su activación y un circuito eléctrico de mando y de elaboración (9), que comprende una unidad de alimentación (12, 13) para la activación de dicho elemento calefactor eléctrico (5), una unidad comparadora (14, 15), alimentada con señales producidas por dicho primer elemento (6) y dicho segundo elemento (7) sensor termoeléctrico y capaz de generar una señal (V1) indicadora de la diferencia entre la temperatura detectada por dicho primer elemento sensor (6) y la temperatura detectada por dicho segundo elemento sensor (7), de confrontar dicha señal de diferencia (V1) con una señal de referencia predeterminada (V T) y de producir una señal de alarma (V2) cuando dicha serial de diferencia (V1) llega al nivel de dicha señal de referencia (V T), y una unidad temporizadora (11), capaz de gobernar en secuencia el funcionamiento de dicha unidad de alimentación (12, 13) y de dicha unidad comparadora (14, 15).
