Virtual Instrumentation Case Study

Application

Boeing used LabVIEW and 70 PXI chassis to

collect over 400 channels of acoustic data

simultaneously in their research to decrease

noise during takeoff

NI Products

LabVIEW, PXI

"Using NI software and hardware, we were able to

create a high-end, low-cost system that could distribute the acquisition system across multiple chassis, tightly synchronize all channels, provide high channel count with full bandwidth on all channels simultaneously, and

allow virtually unlimited channel-count expansion “

Oil Wells Vibration Monitoring for Vietsovpetro

• Applications: Vietsovpetro wants to drill

more oil wells between existing wells to

maintain output level when some existing

wells are depleted This system is to

monitor the vibration during drilling to

alert operator if drilling shaft is about to

touch the existing wells System was

developed by NI partner AIC
