Abstract

EN UN DISPOSITIVO DE MEDICION PARA REGISTRO LIBRE DE CONTACTO DEL CONTORNO INTERIOR DE PIEZAS DE CONSTRUCCION SE BOBINA EN UN SOPORTE (12) UNA BOBINA DE MEDICION (13) POR LA QUE PASA CORRIENTE ALTERNA DE ALTA FRECUENCIA. LA BOBINA DE MEDICION (13) SE RODEA DE UN MANGUITO PROTECTOR (15) CON VENTANAS LONGITUDINALES (24) DE LA MAYOR SUPERFICIE POSIBLE QUE SE FABRICA DE ACERO ENDURECIDO MUY RESISTENTE AL DESGASTE. CON MOTIVO DE LA ESPECIAL FORMACION DEL MANGUITO DE PROTECCION (15) LA DISMINUCION OCASIONADA POR LA CONDICION MATERIAL DEL MANGUITO ES MUY PEQUEÑA LA FORMACION DE CORRIENTE TURBULENTA EN EL CONTORNO INTERIOR. EL MANGUITO DE PROTECCION (15) TIENE UN PEQUEÑO CIERRE Y ES FACIL Y RAPIDAMENTE INTERCAMBIABLE.
