Naaah. Dig up a retired PC, like an old Win98 box. You now have all the hardware, and most of the software, to record the transducer output at more than adequate sample rates. Two channels, 16-bit resolution per channel, ~44,000 samples/second.
I'm happy to be corrected but....
I'm not aware of you having recorded actual pressure readings from a pressure transducer. Your own page indicates the piezo-electric transducers you use indicate pressure rate of change (1st derrivative of pressure), but that's a far cry from pressure.
