The NI 9237 (part number 779521-01) is a C Series module from National Instruments designed for high-accuracy bridge-based sensor measurements. It features four simultaneously sampled analog input channels, each capable of 24-bit resolution and a maximum sampling rate of 50 kS/s per channel. The module is optimized for strain, load, pressure, and torque measurements using full-bridge, half-bridge, and quarter-bridge sensors. It provides integrated excitation, shunt calibration, and support for remote sensing to ensure precise and stable measurements. The NI 9237 is compatible with CompactDAQ and CompactRIO systems, making it suitable for a wide range of structural test and monitoring applications.
