RE: Vibration Transducers
check out a few accelerometer vendors/manufacturer's such as Entek, Vibrametrics, PCB, Columbia Research, Wilcoxon, etc.

RE: Vibration Transducers
If it is a maximum acceleration criteria then use an accelerometer (very common now).
If it is maximum velocity then use a velocity probe (they are getting rare these days. It is necessary to integrate the acceleration signal to get velocity. Errors are introduced when the signal is complex.
If it is displacement, a LVDT (linear variable displacement transducer or laser) can be used to directly measure displacement. Displacement from an acceleration signal requires double integration of acceleration signal, which can result in significant errors when there is a complex signal and particularly if you are measuring a low frequency signal.
