The NI-9231 is a high density channel sound and vibration measurement module suitable for measurements with Integrated Electronic Piezoelectric (IEPE) and non-IEPE sensors such as accelerometers, tachometers, and proximity sensors. It enables measurements with a large dynamic range for modern measurement microphones and accelerometers as well as simultaneous sampling. The NI-9231 has a TEDS input path and a 2 mA IEPE excitation source that can be turned on and off, eliminating the need for external sensors and simplifying the data acquisition system.
