Claim 5:
6. A method of producing an ultrasound sensor for non-destructive testing of a test object, comprising:
providing an ultrasound transducer;
providing a first induction coil having a first outer diameter;
providing a second induction coil having an outer diameter which is greater than the first outer diameter;
electrically coupling the first induction coil to the ultrasound transducer; and
electrically coupling the second induction coil to the ultrasound transducer in parallel with the first induction coil,
wherein the first induction coil provides a first inductance, the second induction coil provides a second inductance and the first inductance is less than or equal to the second inductance, and the first induction coil and the second induction coil are arranged to electrically energise the transducer when the first induction coil and the second induction coil are inductively coupled to receive power from a remote source, and the transducer, the first induction coil and the second induction coil are mounted in a substantially coaxial and coplanar arrangement.
