NI SC Express High-Performance Strain Measurement System for PXI Platform

Configure Page for: Print PDF Rich Text
  • Up to 40 strain channels in a 5-slot PXI chassis
  • Up to 0.02% accuracy; 24-bit ADC per channel; antialias and digital filtering
  • 102.4 kS/s/ch sample rate with NI PXIe-4331, 25 kS/s/ch sample rate with NI PXIe-4330
  • Software-selectable excitation voltage per channel (0.625 to 10 V)
  • Built-in programmable quarter-, half-, and full-bridge completion, and shunt calibration per channel


The NI SC Express High-Performance Strain Measurement System on the PXI platform consists of an 8-channel bridge input module with 25 kS/s/ch (NI PXIe-4330) or 102.4 kS/s/ch (NI PXIe-4331) sample rates, a front-mounting terminal block (NI TB-4330), and a 5-slot chassis with an integrated controller (NI PXIe-1073). You can choose one to five bridge input modules for up to 40 channels in the PXI system.

Specifically designed for bridge-based measurements, each PXI Express module features integrated signal conditioning that provides direct connectivity to your strain gages and other bridge-based sensors. The NI PXIe-4330 and PXIe-4331 modules provide remote sensing, internal bridge completion, and shunt calibration configurations per channel. Additionally, the 24 bits of resolution, along with antialias and digital filtering options per channel, offer superior strain accuracy.

This system is compatible with Microsoft Windows OSs and uses easy and powerful NI-DAQmx driver software. A free copy of NI LabVIEW SignalExpress LE for Windows is included so you can quickly acquire, analyze, and present data without programming.

In addition to LabVIEW SignalExpress, SC Express modules are compatible with LabVIEW, NI LabWindows™/CVI, and NI Measurement Studio. SC Express modules are also compatible with ANSI C/C++, C#, Visual Studio .NET, and Visual Basic 6.0.
