Product Description

The NI 9234 is a high-performance 4-channel sound and vibration input module engineered for precise dynamic signal acquisition in demanding industrial and research environments. Designed for NI CompactDAQ (cDAQ) and CompactRIO (cRIO) systems, the NI 9234 offers 24-bit resolution, IEPE/ICP sensor compatibility, and an impressive sampling rate for accurate measurements of vibration, noise, and acoustic signals.

With built-in IEPE excitation, the NI 9234 supports accelerometers, microphones, and other dynamic sensors commonly used in vibration testing, NVH studies, and machinery diagnostics. Its wide bandwidth and low noise floor make it ideal for structural analysis, rotating machinery testing, predictive maintenance, and environmental noise studies.

The NI 9234 provides a robust, reliable platform for engineers performing dynamic data acquisition, modal analysis, sound measurement, and industrial condition monitoring.
