Test & Measurement
New from National Instruments is the PXIe-4331, the latest in the SC Express family of high-performance data acquisition (DAQ) modules with built-in signal conditioning.
The device is a simultaneous high-speed bridge input module that provides signal conditioning for dynamic measurements from strain, pressure, torque and load sensors. The PXIe-4331 increases the speed of bridge-based measurements and, with PXI Express (PXIe), provides 250 MBps of dedicated bandwidth per device to give engineers the freedom to increase channel count without compromising sampling rates or data throughput.
The module features eight channels with 24-bit analog-to-digital converters (ADCs) per channel and 102,4 kSps per channel sampling rate. To improve accuracy and reject noise, the module offers antialiasing and digital filters per channel. Additionally, it includes an independent programmable 0,625 to 10 V excitation voltage on each channel for flexibility and fault protection. The 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 synchronising across multiple chassis. The simultaneous sampling, high sample rate and channel synchronisation features make the module well suited for structural test applications such as fatigue and impact test, design validation and other dynamic tests, which are common in industries such as automotive, aerospace, defence and renewable energy.
The PXIe-4331 includes NI-DAQmx driver software with support for multidevice tasks, making it possible for engineers to easily synchronise multiple modules. Engineers can combine the DAQ module with a variety of NI hardware including other SC Express modules, X Series DAQ devices, dynamic signal acquisition products and more than 1500 types of I/O available on the PXI platform. The PXIe-4331 also integrates with NI software including LabVIEW, the LabVIEW real-time module and DIAdem.
