Ultrasound sensors and 40MSPS ADC board

[Roland]

I am looking for a source of piezo sensors for a contact ultrasound sensor.
Or a couple of transducers to play with. Does anyone know of a source.

Also looking for an Eval board with a fast ADC 40MSPS or higher with some
RAM and an interface for < $100.

Hi Roland,

You did not specify what frequency you are interested in, but I recently
bought a couple of 40Khz sensors from mouser, in the US. Their product
number is 255-400SR12. Check out www.mouser.com

Also, Velleman makes 40Khz ultrasonic sensors. Their part number is MA40A5R,
and there is a small do it yourself electronics place here in the Northeast
US who sells them. I don't know of any others. I don't know about the Eval
board. Maybe someone else on this forum can help you with that.

hth,

Joe
