PCI-4462

The NI PCI-4462 is a high precision data acquisition board designed for sound and vibration applications. It features a 24-bit sigma-delta analog-to-digital converter (ADC) with a dynamic range of up to 118 dB and six different gain Settings for precise measurements of microphones, accelerometers and other converters with very high dynamic range.
With a 24-bit sigma-delta analog-to-digital converter (ADC), the PCI-4462 is ideal for applications such as noise emission testing and sound holography. With a dynamic range of 118dB and six different gain Settings, it can also be used in areas such as vibration analysis and machine condition monitoring.
The NI PCI-4462 is suitable for a variety of application scenarios, including but not limited to:
Sound testing: The PCI-4462 can be used for accurate measurement and analysis of sound signals, including applications such as audio spectrum, noise emission, and sound holography.
Vibration analysis: PCI-4462 can be used for the acquisition and analysis of vibration signals, including vibration testing, mechanical fault diagnosis, vibration control and other applications.
Machine condition monitoring: PCI-4462 can be used for real-time monitoring and predictive maintenance of machine conditions, including the monitoring of vibration, temperature, pressure and other parameters of machine components such as bearings, gears, and housings.
Audio processing: PCI-4462 can also be used for audio signal processing and editing, such as audio compression, equalization, noise reduction and other processing.
In short, the NI PCI-4462 is suitable for scenarios requiring high-precision data acquisition and processing, such as sound, vibration, machine condition monitoring and other fields.
