NI 9235 and 9236 quarter-bridge strain gage modules are designed for higher-channel-count, dynamic strain measurement systems based on NI CompactDAQ, CompactRIO, or other compatible C Series hardware. With eight simultaneous channels per module, you can make more measurements with a smaller, more channel-dense system. Simultaneous sampling is important for higher-speed acquisitions where it is necessary to compare results from different locations at a particular instant in time, such as impact tests.

For a bridge-based module with a higher sampling speed or the ability to implement full- and half-bridge as well as quarter-bridge measurements, try the NI 9237 C Series simultaneous bridge module.
