The Proximity ProbeOverview
|
An early vibration transducer is the human finger! An earlier, and much more sensitive one is the lateral line organ of the fishes.
|
The vibration transducer is a device that produces an electric signal that is a replica, or analog, of the vibratory motion it is subjected to. A good transducer should not add any spurious components to the signal, and should produce signals uniformly over the frequency range of interest. |
Different types of transducers respond to different parameters of the vibration source, as shown in the following table:
