signal conditioning for piezoelectric transducer

I have to measure the pressure in engine cylinder with a piezoelectric transducer produced by Kisler inc. The signal of transducer will be transformed into 0-5v voltage signal with a charge amplifer.Then, do I still need a signal conditioning card for such voltage acquisition?

sandisland,

Whether you need signal conditioning can depend on many factors. Many situations involve needing excitation for a sensor or to amplify a voltage. If your voltage is already in the range of 0-5v then extra amplification will not provide much benefit. Signal conditioning can also provide filtering or Frequency to voltage conversions for you. The need for signal conditioning will depend on the signal and the measurements you intend to take form the data.

Hope this helps.
