Abstract

PROCEDIMIENTO Y DISPOSITIVO DE TELETRANSMISION DE SEÑALES PARA LA DETECCION Y MEDIDA DEL CONTENIDO DE GAS COMBUSTIBLE EN UNA ATMOSFERA, SIENDO SUMINISTRADAS DICHAS SEÑALES POR UN CAPTADOR ALIMENTADO CON ENERGIA Y ENLAZADO A UNA LINEA DE TELETRANSMISION. EL PROCEDIMIENTO SE CARACTERIZA PORQUE LA ENERGIA NECESARIA PARA LA ALIMENTACION DEL CAPTADOR SE TRANSMITE POR LA LINEA EN FORMA DE CORRIENTE ALTERNA DE INTENSIDAD SENSIBLEMENTE CONSTANTE, CUMPLIENDO DICHA LINEA LA TRIPLE FUNCION DE SUMINISTRADO DE ENERGIA A DICHO CAPTADOR, DE TRANSMISION DE LAS SEÑALES DE INTERROGACION AL MENCIONADO CAPTADOR Y DE LA TRANSMISION DE LAS SEÑALES DE INFORMACION PROCEDENTES DE AQUEL CAPTADOR.
