Abstract

Dispositivo electrónico de vigilancia de funcionamiento de servogato hidráulico, que comprende un circuito de simulación, que recibe la señal de mando del servogato y que suministra una señal de referencia, que representa el desplazamiento teórico del vástago del gato que corresponde al desplazamiento mandado y a las característica del servogato utilizado, un detector de error que recibe la señal de referencia, así como una señal que representa el desplazamiento real del vástago del gato y que suministra una señal de alarma cuando la diferencia entre las dos señales recibidas no está comprendida entre límites admisibles, caracterizado por el hecho de que el circuito de simulación lleva varios elementos, formados por amplificadores operacionales de funciones de transferencia, respectivamente análogos a los del sustractor y del gato subordinado en posición, estando asimilada la función de transferencia de primer orden.
