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 input channels 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. The device has a maximum sampling rate of 102.4 kS/s. 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. The device has a recommended warm-up time of 15 minutes and is self-calibrated on software command. External calibration also is advised to be carried out at least once a year. The PCI-4474 is run using the NI-DAQmx driver software which is compatible with software packages like LabVIEW, LabWindow/CVI, or Measurement Studio. 

The AC/DC coupled device weighs 6.5 oz., and measures 6.9 x 4.2 in. in physical dimensions. It has a recommended operating temperature range of 0 to 50 °C, a storage temperature range of –20 to 70 °C, an operating random vibration of 5 to 500 Hz (0.3 grms), and a non-operating random vibration of 5 to 500 Hz (2.4 grms).

The PCI-4474 is available to be calibrated. While the recommended calibration period for individual parts varies, most parts should be calibrated either annually or every two years to ensure accuracy. If you need the PCI-4474 calibrated, Apex Waves provides options. We offer high-quality NIST accredited calibrations through a 3rd party, with an average turnaround time of 1 to 2 weeks. When you order the PCI-4474 with us, you can request basic (unaccredited) in-house calibration that will calibrate the part to the manufacturer specifications prior to being shipped.
