Main Features and Advantages
Ultra – High – Resolution Data Acquisition
The NI PCI-4462 stands out with its 24 – bit analog input resolution, which offers an exceptionally high level of accuracy in data conversion. This high resolution allows the card to capture even the most minute details of dynamic signals, making it ideal for applications where precision is of utmost importance. Whether it’s measuring the subtle vibrations of high – precision machinery or the faint acoustic signals in noise – sensitive environments, the PCI-4462 ensures that no information is lost, providing users with highly detailed and reliable data for analysis.
High – Speed Sampling and Wide Frequency Response
With a sampling rate of up to 102.4 kS/s per channel and a frequency response ranging from 0 to 44.1 kHz, the NI PCI-4462 can effectively capture a wide variety of dynamic signals. It can keep up with rapidly changing signals, ensuring that transient events and high – frequency components are accurately recorded. This makes it suitable for applications such as vibration analysis of rotating machinery, where high – speed and wide – frequency – range signal acquisition is necessary to detect potential faults and monitor equipment health.
Built – in Anti – aliasing Filter
The card is equipped with a built – in 8th – order Butterworth anti – aliasing filter, which significantly improves the quality of the acquired data. This filter prevents aliasing, a phenomenon that can distort the signal during sampling, ensuring that the captured data accurately represents the original signal. By eliminating aliasing errors, the PCI-4462 provides more reliable and accurate results, reducing the need for additional post – processing to correct signal distortion.
Versatile I/O and Compatibility
In addition to its excellent analog input capabilities, the NI PCI-4462 also features 8 digital I/O lines, providing additional flexibility for system integration. It is fully compatible with NI – DAQmx driver software, which offers an intuitive programming interface for various programming languages, including LabVIEW, C, C++, and Python. This compatibility allows developers to easily customize data acquisition and analysis applications according to their specific requirements, making the PCI-4462 a highly adaptable solution for different projects.
