NATIONAL Instruments has announced the NI PXIe-449x high-channel-count dynamic signal acquisition modules.
The NI PXIe-449x modules provide AC/DC coupling both for sensor measurements with a microphone or accelerometer and voltage measurements from a tachometer or device under test.
According to National Instruments, engineers can use a single device for all their sound and vibration acquisition needs. It is scalable, and when used with LabVIEW, the module allows users to customise their applications and perform real-time monitoring.
The NI PXIe-449x modules feature a choice of 8 or 16 channels with 24-bit analogue-to-digital converters (ADCs) per channel and 113 dB dynamic range. This dynamic range is said to minimise the noise floor, making it easy to detect even the smallest vibration and acoustic signals.
National Instruments claims the use of the NI PXIe-449x modules allows engineers to easily synchronise physical measurements of any type and correlate real-time events.
The modules sync with the NI SC Express family of data acquisition modules, which provide signal conditioning and connectivity ideal for temperature, strain and high-voltage acquisition.
