Description
The NI 9250 with BNC – Sound and Vibration Input Module, part number 783827-01, falls under the category of C Series Analog Input modules designed to cater to a variety of sound and vibration analysis applications. This module is equipped with 2 channels that support a voltage range of ±5 V, making it versatile for different types of measurements.
It is compatible with both IEPE and Non-IEPE sensors, such as microphones and accelerometers, and also supports TEDS (Transducer Electronic Data Sheet) for easy sensor setup and configuration. The module features IEPE signal conditioning, allowing for direct connection of IEPE sensors. Users can select between AC or DC coupling through software, providing flexibility for various signal types.
The NI 9250 boasts a maximum sample rate of 102.4 kS/s per channel, ensuring high-resolution data capture. It is equipped with integrated anti-aliasing filters that automatically adjust based on the sample rate, which helps in preserving the integrity of measured signals.
This module is designed to be compatible with various software applications focused on condition monitoring, order tracking, and frequency analysis, enhancing its utility in a wide range of analysis tasks. Connectivity is facilitated through BNC connectors, offering a reliable and easy-to-use interface for connecting sensors.
Furthermore, the module provides a software-selectable IEPE excitation source, enabling or disabling sensor excitation as needed. The excitation current is also software-selectable for AC coupling, offering additional control over sensor operation. The onboard ADC is a 24-bit Delta-Sigma type with analog pre-filtering, ensuring accurate and precise data conversion. Lastly, it features overvoltage protection up to ±30 V (one channel at a time), safeguarding the module against unexpected voltage spikes.
