Description
The National Instruments PXIe-4340 is a high-precision Displacement Input Module with part number 785068-01 designed to work with a variety of sensors including AC LVDT, AC RVDT, Resolver, and Synchro. It boasts a robust sampling rate of up to 25.6 kS/s per channel across its four concurrently sampled channels, ensuring accurate and synchronized data acquisition.
The module is equipped with a 24-bit ADC resolution for high-resolution measurements and offers flexibility with independently selectable excitation frequency and voltage for each channel, allowing for a tailored setup for different sensor requirements. The built-in remote sensor system is designed to compensate for errors in excitation leads, which is particularly beneficial for long cable runs susceptible to resistance-induced inaccuracies.
Furthermore, the PXIe-4340 includes a self-calibration feature that adjusts radiometric gain and offset to account for any analog drift on the motherboard, ensuring reliable and stable performance over time. The module’s ability to synchronize multiple channels on the same board—with identical excitation frequency and amplitude—makes it an ideal solution for complex measurement systems requiring high synchronization accuracy.
