Abstract

CAPTADOR DE ACELERACIONES AXIALES, Y PRINCIPALMENTE DE DETECCION DE PICADO EN MOTOR DE COMBUSTION INTERNA. COMPRENDE UN ELEMENTO SENSIBLE PIEZOELECTRICO Y MEDIOS DE RECOGIDA DE LAS CARGAS QUE APARECEN A AMBOS LADOS DEL ELEMENTO PIEZOELECTRICO. ESTOS MEDIOS COMPRENDEN UNA CINTA AISLANTE FLEXIBLE (10), QUE PRESENTA SOBRE LA MISMA CARA DOS METALIZACIONES DISTINTAS, CADA UNA DE LAS CUALES COMPRENDE UNA PASTILLA (28, 29) DE CONTACTO CON EL ELEMENTO SENSIBLE PIEZOELECTRICO, ENLAZADA POR UN CONDUCTOR DE ENLACE (11, 12) A UNA ZONA DE METALIZACION (13, 14), CONSTITUIDA POR UNA PASTILLA O UN OJAL METALIZADO. APLICACION A LA DETECCION DEL PICADO O GOLPETEO EN LOS MOTORES DE COMBUSTION INTERNA.
