Wireless and PXI Express Devices for Sound and Vibration
PrintThe NI WLS-9234 wireless dynamic signal acquisition (DSA) module offers 24-bit resolution, a 51.2 kS/s maximum sampling rate, software-selectable IEPE conditioning, and AC/DC coupling. With this new module, you can relay noise, vibration, and harshness (NVH); machine condition monitoring; and structural monitoring data wirelessly over the IEEE 802.11g standard. You also can stream waveform data in real time over Wi-Fi and replace the cost and clutter of cabling with a distributed measurement system. This module also supports direct Ethernet connection.
New sound and vibration DSA modules include the NI WLS-9234 and the NI PXIe-4498.
With the release of the NI WLS-9234 module comes two new PXI Express DSA modules, the NI PXIe-4496 and the NI PXIe-4498. These modules offer 24-bit resolution, 204.8 kS/s maximum sampling rates, and a 114 dB dynamic range. The PXI Express chassis architecture provides both a high-accuracy 10 MHz clock for synchronization and a much higher throughput when compared to PXI. With these modules, you can synchronously acquire data from 272 channels in a single PXI Express chassis at full rates. With the addition of redundant arrays of independent disks (RAID) to the measurement system, bandwidth and storage space are no longer a concern.
