National Instruments launches PXIe module for high-channel count dynamic signal acquisition

January 26, 2011 By Motion Control Tips Editor Leave a Comment

National Instruments (www.ni.com) has released its PXIe-449x devices, which provide AC/DC coupling for sensor measurements with voltage measurements from a tachometer or device under test and an accelerometer or microphone, to allow engineers the use of a single device for their vibration and sound acquisition needs.

The NI PXIe-449x modules provide 113 dB dynamic range and a choice of eight or 16 channels with 24-bit analog-to-digital converters (ADCs) for every channel. The broad dynamic range lessens the noise floor to easily detect even the slightest acoustic and vibration signals. The NI PXIe-449x modules also feature software-selectable gains, which aid engineers to configure gain on every channel for the best possible signal-to-noise ratio.

The NI PXIe-449x modules allow engineers to synchronize physical measurements of any kind and correlate real-time events. The modules seamlessly fit with the NI SC Express family of data acquisition modules, which deliver connectivity and signal conditioning ideal for strain, temperature and high-voltage acquisition. The PXI platform is ideal for design validation, structural test and other dynamic tests as it has the ability to combine modules.

NI PXIe-449x modules are also compatible with the NI Sound and Vibration Measurement Suite. It is an interactive software that allows quick analysis, acquisition and logging of vibration and acoustic measurements. The suite also features ready-to-run applications such as the NI LabVIEW analysis VIs. High-level and NI Sound and Vibration Assistant for performing non-destructive tests.
