The cDAQ-SV1100 product bundle combines the powerful NI-9231 Sound and Vibration Measurement Module with the versatile cDAQ‑9171 CompactDAQ-USB chassis. This solution provides a reliable and flexible platform for sound and vibration measurement applications, from audio test suites to machine condition monitoring.
NI-9231 Sound and Vibration Measurement Module
The NI-9231 is a high-performance module designed for high-channel density sound and vibration signal acquisition. It supports a wide range of sensors, including IEPE and non-IEPE sensors such as accelerometers, tachometers, and proximity probes. With a wide dynamic range, it is ideal for modern measurement microphones and accelerometers and enables simultaneous measurements. The module features a TEDS input path and a 2 mA IEPE excitation source that can be turned on and off to optimize sensor usage and simplify data acquisition system setup.
NI-9231 features:
- Up to 8 differential analog input channels
- Maximum sample rate of 51.2 kS/s per channel
- Analog input measurement range: -5 V to 5 V
- Front connector type: Coaxial Type N (8 connectors)
- No analog input isolation
- No conformal coating
- Enclosed
- Compatible with CompactDAQ and CompactRIO
CompactDAQ USB Chassis cDAQ‑9171
The cDAQ‑9171 is a rugged and portable CompactDAQ USB chassis that enables seamless integration of USB-enabled sensors and electrical measurements. It accommodates a variety of hot-swappable C-Series I/O modules and features four integrated 32-bit counter/timers for additional functionality. The chassis offers simple plug-and-play functionality and controls timing, synchronization, and data transfer between the modules and the host computer.
Additional features of the cDAQ‑9171:
- Continuous waveform measurements thanks to patented NI streaming technology
- Simple and fast measurements with the NI-DAQmx driver software and automatic code generation with the DAQ Assistant
- Bus-powered for high mobility
- Screw-on USB cable for additional security and strain relief
