Each strip is pref. of polarised polyvinylidenefluoride and 3.5mm wide with a circumferentially extending part at the outer end to form an L-shaped transducer. There may be a further strip extending circumferentially around the outer part of the instrument and of a length approximating a whole number of wavelengths of vibration propagating circumferentially in the outer part.
