Description
The National Instruments NI-9237 is a high-performance Strain Bridge Input Module designed for precision measurement applications. This module is capable of interfacing with up to 4 channels, each supporting a sample rate of 50 kS/s per channel which ensures accurate and rapid data acquisition. The 24-bit ADC resolution enhances the quality of measurements, providing detailed and precise results.
The NI-9237 is equipped with various connectivity options including RJ-50 and DSUB connectors, making it versatile for different wiring configurations. Specific front connector types include D-Sub (for part numbers 780264-01 and 780264-02) and RJ-50 (for part number 779521-01), offering flexibility in connection types.
For environments requiring additional durability, the module version with part number 780264-02 is conformal coated, enhancing its resistance to harsh conditions. The module ensures safety and reliability with its 60 VDC, 1000 Vrms transient isolation, protecting both the module and connected devices from electrical transients.
Software compatibility is broad, supporting NI-DAQmx 8.1 or later, which includes integration with LabVIEW, LabWindows™/CVI™, and various programming languages such as Microsoft Visual C++, Microsoft Visual Basic 6.0, Microsoft .NET, and Borland C++. This wide range of supported software makes the NI-9237 a flexible solution for many data acquisition systems.
For optimal performance and reliability, a calibration period is recommended either annually or every two years. This ensures that the module maintains high accuracy and precision over time.
In summary, the National Instruments NI-9237 Strain Bridge Input Module is a versatile and high-performance solution for precise strain measurement applications. Its robust design, combined with high sample rates, advanced connectivity options, and broad software compatibility, make it an ideal choice for engineers and researchers looking for accurate and reliable data acquisition.
