The NI 9232 Measurement System measures three accelerometer, proximity probe, or tachometer channels at 102.4 kS/s per channel with 24-bit resolution and then sends the data to a host PC over USB, Ethernet, or 802.11 Wi-Fi.

Measurement Bundle Overview
The hardware for an NI CompactDAQ single measurement bundle consists of a USB, Ethernet, or 802.11 Wi-Fi chassis and one of the over 50 NI C Series measurement-specific modules. These small rugged bundles are ideal for portable or distributed measurements.

The chassis controls the timing for the module and handles communication with the PC over the USB, Ethernet, or 802.11 Wi-Fi bus. Additionally, all NI CompactDAQ chassis include four counter/timers that you can access through a digital I/O module like the NI 9401.

The NI 9232 is a 3-channel C Series dynamic signal acquisition module for making industrial measurements from integrated electronic piezoelectric (IEPE) and non-IEPE sensors with NI CompactDAQ or NI CompactRIO systems.

The NI 9232 delivers 99 dB of dynamic range and incorporates software-selectable AC/DC coupling and IEPE signal conditioning for accelerometers, tachometers, and proximity probes. The three input channels simultaneously digitize signals at rates up to 102.4 kHz per channel with built-in antialiasing filters that automatically adjust to your sampling rate.

Recommended Software
NI sound and vibration analysis software, such as the NI Sound and Vibration Measurement Suite and the NI Sound and Vibration Toolkit, provides signal processing functionality for performing audio measurements, fractional-octave analysis, frequency analysis, transient analysis, and order tracking. NI analysis software features NI Sound and Vibration Assistant interactive software for quickly acquiring, analyzing, and logging acoustic, noise, and vibration data. With a configuration-based, flexible measurement library and open-analysis capability, the Sound and Vibration Assistant is designed for quick data capture through a unique software-based measurement approach to create customized applications.
