Description
The National Instruments NI-9250 C Series Sound and Vibration Input Module, part number 783827-01, is a sophisticated device designed for a wide range of applications requiring high-quality sound and vibration data acquisition. This module falls under the category of C Series Analog Input devices and is specifically designed to cater to both IEPE and non-IEPE sensors, including microphones, accelerometers, and Smart TEDS sensors, making it a versatile choice for various measurement needs.
The NI-9250 features a 2-Channel, ±5 V Range, allowing for the capture of detailed and accurate data across two distinct channels simultaneously. This capability is particularly important for applications that require synchronized data acquisition from multiple sources. With a maximum sample rate of 102.4 kS/s/ch, the module ensures that high-frequency signals are accurately captured without missing critical information.
One of the key features of the NI-9250 is its IEPE signal conditioning, coupled with software-selectable AC/DC coupling, which significantly enhances its compatibility with a wide range of sensor types. This feature ensures that users can seamlessly switch between different sensor types without the need for additional hardware, making it a cost-effective solution for diverse measurement tasks.
Furthermore, the module comes equipped with integrated anti-aliasing filters that are adjustable to the sample rate. This feature is critical for ensuring that the signal integrity is maintained by minimizing the effects of aliasing, thereby ensuring that the data acquired is accurate and reliable. BNC connectors are provided for IEPE signal excitation source and TEDS input path, offering easy and secure connections for data acquisition setups.
The NI-9250 also features a software-selectable IEPE excitation source enable/disable option, allowing users to easily configure the module based on the requirements of the connected sensors. The module’s 24-bit, Delta-Sigma ADC with analog pre-filtering ensures high-resolution data acquisition, capturing the nuances of the measured signals with high fidelity. Additionally, the module is designed with overvoltage protection of ±30 V maximum on one channel at a time, safeguarding the device against unexpected voltage
