This line of sensors was developed specifically for ultrasonic inspection of hollow axles. They exist in different configurations, for different diameters. Thanks to the surface slots, the coupling fluid remains on the sensor, ensuring proper coupling, without having to use special adduction systems. The head, is equipped with two connectors on the ends to allow reversing the output of the ultrasonic beam. Scope of supply includes: – Single-crystal borosonde head with double connector for IN/OUT beam orientation; – L=1300mm decomposable connecting rod with overhead joint and quick connection borosonde head; – Magnetic centering bezel; – Connecting cable with 90° coaxial connector; – EN-12668-2 transducer certificate. Head Configuration: – Borosonde diameters: 30, 45, 56, 65, 85, 90 mm; – Diameter tolerances: 3 to 6 mm according to the nominal diameter; – Dim. Crystals: 8×9 ,14×14, 14×20, 20×22 mm (depending on borosonde diameter); – Frequency: 2 to 5 MHz; – Angles: 35° to 70°, (or 70° secant);
