Overview

Product overview

Key product information and technical features.

The PXIe-4331 integrates data acquisition and signal conditioning for dynamic strain, load and pressure measurements. Its eight differential analog input channels provide 24-bit resolution with a maximum sample rate of 102.4 kS/s.

The module supports full-, half- and quarter-bridge configurations, with input ranges of ±25 mV/V and ±100 mV/V. Per-channel filtering and independently programmable excitation provide integrated signal conditioning for bridge measurements.
