Title (EN) EDDY CURRENT ARRAY PROBE HAVING AN INSULTED TRANSCEIVER UNIT AND EDDY CURRENT EXAMINATION METHOD USING SAME
(FR) SONDE À RÉSEAU DE COURANTS DE FOUCAULT AYANT UNE UNITÉ D'ÉMISSION-RÉCEPTION ISOLÉE ET PROCÉDÉ D'EXAMEN PAR COURANTS DE FOUCAULT L'UTILISANT
(KO) 송수신부가 절연된 배열 와전류 탐촉자 및 이를 이용한 와전류 탐상 검사 방법
Abstract:
(EN) The present invention provides an eddy current array probe having an insulated transceiver unit and an eddy current examination method using the same. The eddy current array probe may comprise: a body; a plurality of magnetic excitation elements arranged in one row along the periphery of the body; and a plurality of magnetic field detecting elements arranged in the one row at positions spaced apart a pre-set interval from the magnetic excitation coil.
(FR) La présente invention concerne une sonde à réseau de courants de Foucault dotée d'une unité d'émission-réception isolée et un procédé d'examen par courants de Foucault l'utilisant. La sonde à réseau de courants de Foucault peut comprendre : un corps ; une pluralité d'éléments d'excitation magnétique disposés en une rangée le long de la périphérie du corps ; et une pluralité d'éléments de détection de champ magnétique agencés dans la rangée à des positions espacées d'un intervalle prédéfini de la bobine d'excitation magnétique.
(KO) 송수신부가 절연된 배열 와전류 탐촉자 및 이를 이용한 와전류 탐상 검사 방법을 제공한다. 배열 와전류 탐촉자는 몸체, 상기 몸체의 둘레를 따라 하나의 열로 배치되는 복수개의 자기여기용 소자 및 상기 하나의 열 상에서 상기 자기여기용 코일과 기 설정된 간격만큼 이격된 위치에 배치되는 복수개의 자장검출용 소자를 포함할 수 있다.
