High temperature flexural ultrasonic transducer for non-contact measurement applications.
IEEE ISAF 2016. Darmstadt, Germany (21.09.2016-25.09.2016)
Conference or Workshop Item, Bibliographie
Abstract
A prototype flexural ultrasound transducer capable of operating at high temperatures was designed for noncontact measurement applications. A doped bismuth titanate was used as the piezoelectric element; the construction of the transducer was designed using materials and bonding capable of operating at temperatures up to 500oC. The bismuth titanate was characterised by X-ray diffraction, differential thermal analysis and impedance analysis; the transducer response was measured using laser interferometry at room temperature. The resulting frequency spectrum showed clear resonance peaks, indicative of an operational flexural transducer.
