Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA MEDIR VARIACIONES DE CAPACIDAD EN UNA VALLA DE DEFENSA.CONSISTE EN APLICAR MEDIANTE UN TRANSMISOR (S) UNA TENSION ALTERNA A UNO DE LOS ELECTRODOS (1S, 3S, 5S, 7S) MIENTRAS QUE LOS RESTANTES ELECTRODOS (2E, 4E, 6E), ESTAN PUATOS A TIERRA COMO ELECTRODOS DE RECEPCION. EN CADA CIRCUITO EXISTE UN DISPOSITIVO DE MEDICION (IM1 A IM7) CUYOS VALORES SE COMPENSAN CON FACTORES DE PERTURBACION.
