(EN) ULTRASONIC INSPECTION DEVICE WITH SOLID COUPLING ELEMENT
(FR) DISPOSITIF D'INSPECTION À ULTRASONS AVEC ÉLÉMENT DE COUPLAGE SOLIDE
Abstract
(EN)
An inspection device (300) has an ultrasonic transducer (304) encased in a couplant block (302) mounted in a housing (328). The housing (328) has a pair of encoders (340, 342) mounted thereto. The transducer (304) is mounted to scan perpendicular to the contact surface (306) of the block (302). A coupling block with a PTFE layer on the contact surface is also provided.

La présente invention concerne un dispositif d’inspection (300) qui a un transducteur à ultrasons (304) intégré dans un bloc de couplage (302) monté dans un boîtier (328). Le boîtier (328) a une paire d’encodeurs (340, 342) montés sur celui-ci. Le transducteur (304) est monté pour balayer perpendiculairement à la surface de contact (306) du bloc (302). Un bloc de couplage avec une couche en PTFE sur la surface de contact est également fourni.
