National Instruments introduces the PXIe-4492 module, designed for sound and vibration applications

National Instruments (NI) today announced the launch of the PXIe-4492, a high-precision Data acquisition (DAQ) module designed for sound and vibration applications. The module integrates eight synchronous sampling analog input channels in a single PXI Express module, providing an adaptable channel arrangement that meets the needs of most single-frame noise, vibration, and roughness (NVH) tests.

The PXIe-4492 module features high performance with a sample rate of 204.8 kS/s, dynamic range of 113 dB, two gain Settings, and AC/DC coupling capability of 0.5 Hz. It supports 24-bit analog input and IEPE constant current signal conditioning, making it ideal for precise measurements with microphones, accelerometers, and other sensors with a large dynamic range. In addition, the module includes a built-in anti-aliasing filter that automatically adjusts to the sampling rate, six software-selectable input gain ranges, and TEDS smart sensor support to help ensure proper safety configuration.

The introduction of the PXIe-4492 module is expected to play an important role in improving the efficiency and accuracy of sound and vibration testing. It is not only suitable for noise, vibration and acoustic roughness (NVH) analysis, but also for applications such as large microphone arrays and dynamic structure testing. The module’s high performance and reliability make it ideal for audio test and measurement, noise and vibration diagnostics, machine condition monitoring, automotive testing and more.
