I have a charge-mode piezoelectric dynamic pressure sensor (datasheet link) that I want to read a signal from. If you look at the datasheet it says the sensor outputs are in a balanced and floating configuration, which I think means its output is a differential signal. Since it is a charge mode device, I will need to use a special charge amplifier to condition the signal to a low impedence voltage mode signal.
So I have two question related to this topic:
Is there any reason why I can't or shouldn't treat the output of this charge-mode sensor as a single-ended signal by tying the negative pin to ground? This would allow me to use a coaxial cable for the connection between the sensor and my charge amplifier. The charge amplifier that I currently have is only meant for RSE signals, so it's input connector is BNC.
Are there any benefits to using a differential signal over a balanced line rather than a single ended signal running over shielded coax?
This sensor will be operating right next to a DC generator, so it will be an electrically noisy environment.
