NI intros PXI Express Module

NEW DELHI, INDIA: National Instruments today announced the launch of NI PXIe-449x devices, the most flexible high-channel-count dynamic signal acquisition (DSA) modules.

The modules provide AC/DC coupling both for sensor measurements with a microphone or accelerometer and voltage measurements from a tachometer or device under test, making it possible for engineers to use a single device for all their sound and vibration acquisition needs, said a press release.

“We need scalable data acquisition hardware and software that yields accurate data efficiently,” said Michael James, vice president at Blue Ridge Research and Consulting.

He added that leveraging LabVIEW with the NI PXIe-449x DSA module would fulfill their needs by enabling them to customize their applications and perform real-time monitoring.

The NI PXIe-449x modules feature a choice of 8 or 16 channels with 24-bit analog-to-digital converters (ADCs) per channel and 113 dB dynamic range. The large dynamic range minimizes the noise floor, making it easy to detect even the smallest vibration and acoustic signals.

The modules also provide software-selectable gains that help engineers configure gain on each channel for the best signal-to-noise ratio possible.

With the NI PXIe-449x modules, engineers can easily synchronize physical measurements of any type and correlate real-time events. The modules sync effortlessly with the NI SC Express family of data acquisition modules, which provide signal conditioning and connectivity ideal for temperature, strain and high-voltage acquisition, the release said.

It is also compatible with the NI Sound and Vibration Measurement Suite, an interactive software for quickly acquiring, analyzing and logging acoustic and vibration measurements, the release added.
