Frequency response of pressure transducer for dynamic measurement

Good Afternoon,

I am working on a project that involves working with pressure transducers for dynamic pressure measurment of air. The pressure transducers in question have a range of 25psi which produces an output of 100mV (at 25psi).

What I would like to know (for the moment) is how to calculate / determine the frequency response of the transducer so that I may be able to connect the transducers output to a suitable amplifier.

The information I have to hand includes the following:
  • Pressure Range = 25psi
  • Full Scale Output = 100mV
  • Input & Ouput impedance = 1000Ω
  • Resolution = ∞
  • Natural Frequency = 300khz
  • Sensing Principle = Fully active four arm wheatstone bridge isolated silicon on silicon
I have read on the internet that as a rule of thumb, the frequency response is approximately one third of the natural frequency, but I do not know how reliable or accurate this is.

I have contacted the manufacturer of the transducers but to date have had no response.

I look forward to, and welcome any assistance.

Regards,

Rob.
