Abstract
This application relates to a wireless sensor (10) suitable for non-destructive testing of a test object. The sensor comprises a transducer (12) and an electrically conductive transducer coil (16) configured to define an enclosure and being electrically coupled to the transducer to enable the transducer to be inductively operated by a remote device. The enclosure defined by the transducer coil has an internal width dimension that is wider than a corresponding width dimension of the transducer.
Claims18
A wireless sensor suitable for non-destructive testing of a test object, the sensor comprising:
- a transducer;
- and
- an electrically conductive planar transducer coil arranged in a generally parallel relationship to an upper surface of the transducer and transversely spaced apart therefrom in a range from zero to no more than five times a thickness of the transducer, the transducer coil configured to define an enclosure and being electrically coupled to the transducer to enable the transducer to be inductively operated by a remote device,
- wherein the enclosure defined by the transducer coil has an internal width dimension that is wider than a corresponding width dimension of the transducer and a center of the transducer coil is axially aligned with a center of the transducer.
