The PXIe-4480 supports the use of charge mode piezoelectric sensors without the need of any additional circuitry. For more information about the connection diagram you can reference the PXIe-4480/4481 User Manual
on page 18.
- To confirm that your charge sensor is compatible with the PXIe-4480:
You need to determine the full charge range of the sensor: Full Charge Range = Sensitivity * Sensor's Range
We have a charge sensor with +/- 15 pC/µε of sensitivity and +/- 1500 µε of range. The Full Charge Range will be:
Full Charge Range = +/- 15 pC/µε * +/- 1500 µε = +/- 22500 pC
This sensor will exceed the signal range of the PXIe-4480 (which is 20000 pC), so it will not work unless your expected measurements won't use the full range of the sensor and they are still within the module's range.
