"I don't seem to be getting anything" isn't nearly enough information. Do you have the +200V DC bias? Have you measured it? What level are you reading the input from the transducer? It only puts out a few millivolts of signal, basically you have to run the output through a capacitor, resistor and a clip-limiter (diodes to Vcc and ground) so that you don't blow out your opamp, then into an opamp with some gain (try 100x) before you would have much of a signal to look at on a scope.
