The vibration characteristics of a number of commercially prepared Ni-Co-Cr alloy magnetostrictive transducers have been measured. The behaviour of a single transducer coupled to a stainless steel probe, resonant at 13 kHz, has been examined under unloaded conditions and it is shown that the length of the transducer is not critical to within +_ 1 in of the length calculated to be resonant at 13 kHz. Further experiments with 3 transducers attached to the probe are described. The suitability of the existing method of mounting the system at the nodal point of the probe has been investigated and the results indicate that some improvement in probe output should be possible by the use of a flexible mounting at the nodal point of the probe. Further experiments carried out under load conditions show that it is difficult to know accurately the resonant frequency of the system as the response is quite flat.
