Product Description
The PXIE-4330 is a high-performance PXI Express strain/bridge input module from National Instruments (NI). Here are some detailed product details about the PXIE-4330:
Functions and Applications:
The PXIE-4330 is designed for high-performance strain, load, force value and moment measurement.
It is capable of automatic, simultaneous measurements of quarter, half and full Bridges, and is particularly suitable for test applications requiring high channel count architectures, such as wind tunnels, bridge inspection and crash testing.
Technical specifications:
Accuracy: Up to 0.02%, providing high precision measurement.
Sampling rate: Up to 25kS/s (25,000 samples/second) per channel, supporting high-speed data acquisition.
Input channels: Typically has 8 analog input channels that can be scaled up to 136 channel systems in a single chassis and thousands of channels when synchronized across multiple chassis.
Input range: Multiple bridge resistors and voltage ranges are supported, such as -25 mV/V to 25 mV/V and -100 mV/V to 100 mV/V.
Bridge design: The proportional design makes the ADC chip reference to the excitation voltage, and no longer depends on the stability and accuracy of the excitation voltage.
Synchronization and calibration:
The PXIE-4330 supports simultaneous measurement of multiple modules and chassis, and can achieve inter-channel skew errors as low as 5ppb through the included driver software.
Each channel can be configured entirely via software for bridge measurement or direct voltage measurement.
Extensibility:
In addition to the strain/bridge input function, it can be used in combination with other NI modules, such as the NI PXIe-4353 thermocouple module, to meet a wider range of measurement needs.
Software support:
Support NI’s LabVIEW and other data acquisition and analysis software to facilitate data acquisition, processing and analysis.
Physical characteristics:
The PXI Express slot size is usually used, and the standard PXI Express chassis is supported.
The module design is compact and suitable for integration into various test systems.
