Can anyone help me with it? : Thanks, : lns ------------ End Original Message ------------ Hi, It depends on how you want to excite the parts and how you want to receive the vibrations. Also depends on the sample shape and dimensions. We market two transducer types, both of which operate by exciting the part with a swept sine wave and receiving the vibration with piezo transducers. One operates best as transmitter between 50 Hz and 30 KHz, and the other operates best as both transmitter and receiver between 10 KHz and 1 MHz. If you are using impact excitation and only interested in lower frequency vibrations, then Microphones (20 KHz upper limit) or accelerometers (upper limit 40 KHz) are suitable. Regards, Godfrey Hands.
