National Instruments introduced the PXIe-4331, a PXI Express data acquisition module for high-speed bridge-based measurements.
According to National Instruments, the data acquisition module increases accuracy and bandwidth for high-channel-count strain, load and pressure measurement systems.
The NI PXIe-4331 has built-in signal conditioning, and is a simultaneous high-speed bridge input module that provides signal conditioning for dynamic measurements from strain, pressure, torque and load sensors.
The module increases the speed of bridge-based measurements and, with PXI Express, provides 250MB/s of dedicated bandwidth per device to give engineers the freedom to increase channel count without compromising sampling rates or data throughput.
The NI PXIe-4331 features eight channels with 24-bit analogue-to-digital converters (ADCs) per channel and 102.4kS/s per channel sampling rate. It also offers antialiasing and digital filters per channel.
The NI PXIe-4331 also provides remote sensing, internal bridge completion and shunt calibration options per channel. The 8-channel bridge input module can scale to a 136-channel system in a single chassis and thousands of channels when synchronizing across multiple chassis.
The simultaneous sampling, high sample rate and channel synchronization features make the module suited for structural test applications such as fatigue and impact test, design validation and other dynamic tests.
