Driving a piezoelectric ultrasound transducer/sensor

Hi, Daniele,

When you say "ultrasound transducer/sensor" do you mean like medical ultrasound or like sonar ultrasound?

-d2

The device is gonna be a not invasive transit time ultrasonic flowmeter, where the probes are clamped outside the pipe line.

Trasducer center frequency will be around 2.0 MHz.

What I need is something able to charge the piezoelectric membrane with square or sinusoidal pulses, hold the electric field on the membrane, discharge it to generate the ultrasonic signal.

Having a built-in amplifier to amplify the echoes it's a plus but not needed for the driving device.

Hope I've clarified my issue.

Regards,

Daniele

Daniele,

So, the signal you need to drive is at 2 MHz?

-d2

exactly.
