| Abstract | Employing a portable on-site fabrication kit, high temperature integrated ultrasonic transducers (IUTs) made of bismuth titanate piezoelectric film, of thickness greater than 50 µm, have been caoted directly onto a modified CF700 turbojet engine outer casing, oil sump and supply lines and gaskets using sol-gel spray technology. Transducers top electrodes, electrical wires, conducting adhesive bond, connectors and cables have all been successfully tested for temperatures up to 500°C. The excellent ultrasonic performance of these IUTs is demonstrated in this paper and the potential applications for the non-intrusive real-time temperature and lubricant oil quality and metal debris monitoring have been identified and discussed. |
