National Instruments PCI-4474 Sound and Vibration Device

The National Instruments PCI‑4474 (Part numbers: 778729-01 and 778778-01) Sound and Vibration Device has four simultaneously sampled differential analog inputs with 24-bit determination ADCs that are inspected at a programmable rate. The high determination gives the essential precision to make the NI PCI‑4474 device appropriate for sound and vibration examination applications. Remarkable estimations can be accomplished with a NI PCI‑4474. For instance, when examining at 51.2 kS/s and utilizing a 16 k FFT, a dynamic range more prominent than 110 dB can be accomplished. Utilizing cutting edge delta-sigma adjusting ADCs, the NI PCI 4474 Sound and Vibration Device accomplishes low noise and low contortion. Since these ADCs utilize a 1-bit quantifier oversampled at a different of the predefined inspecting rate, they create exceptional linearity. To a great degree level, direct stage, lowpass computerized channels shape the quantization noise from the band of interest. Utilizing the delta-sigma balancing ADCs, the PCI‑4474 is safe to the DNL twisting related with customary information securing gadgets.

The user can also apply arranged examination to dynamic signals produced by a powered system that will offer rotating or rejoining parts, including: turbines, blowers, pumps, and motors. With the additional ability for online processing, the user can effortlessly make adaptable applications for condition-based checking and prescient support. The National Instruments PCI 4474 Sound and Vibration Device also has software-selectable AC/DC coupling, no analog output channels, 3.4 Hz High Pass Filter Cutoff Frequency, and SMB front connectors.
