Abstract

DIPOSITIVO DE SEGURIDAD, EN EL CONTROL DE MAQUINAS-HERRAMIENTA, POR MEDIO DE SEÑALES ELECTRICAS, QUE PRESENTA UN DETECTOR DE CERO CAPAZ DE CORTAR EL SUMINISTRO DE CORRIENTE. SE PREVE UNA UNIDAD DE CONTROL ALEJADA DE LA MQUINA, QUE TRANSFIERE ORDENES A TRAVES DE UN CALBLE A UNA UNIDAD RECEPTORA (H), QUE CONTROLA A UNOS CONVERTIDORES CONECTADOS A UNA PLURALIDAD DE SENSORES DE LAS VALVULAS SELECTORAS LA SALIDA DEL RECEPTOR (H) ESTA CONECTADA A CONVERTIDORES DE SEÑAL (L), AMPLIFICADORES (M) Y A UN DETECTOR DE CERO (P) QUE COMPRENDE UNA PUERTA (34), UN CIRCUITO DE RETARDO DE TIEMPO (35) Y UN CIRCUITO DE COMPARACION (36). EL DETECTOR DE CERO (P) ES CAPAZ DE CORTAR EL SUMINISTRO DE CORRIENTE AL AMPLIFICADOR (M), AUNQUE NO SE DETECTE SEÑAL A LA SALIDA DEL RECEPTOR (H). DE APLICACION EN MAQUINAS ELECTROHIDRAULICAS Y ELECTRONEUMATICAS.
