| Zusammenfassung: | A wireless ultrasound non-destructive testing (NDT) sensor 404 which emits a pulse of ultrasound energy into a test object and receives an echo signal. The sensor comprises an ultrasound transducer 406 and an induction coil 408. The internal diameter of the induction coil is smaller than the outer diameter of the ultrasound transducer, which provides an improved inductive coupling between the sensor and a remote energising device. The sensor is arranged for the coil to be positioned in parallel with the ultrasound transducer. The induction coil and ultrasound transducer are positioned side by side in a non-overlapping arrangement, which inhibits interference in use. |
