Overview

Product overview

Key product information and technical features.

The NI-9235 measures strain from 120 Ω quarter-bridge sensors using eight simultaneously sampled inputs. Simultaneous acquisition supports comparisons between channels at the same instant during dynamic strain measurements.

The enclosed C Series module uses spring-terminal connections and provides built-in voltage excitation for quarter-bridge sensors. Its specified input range is -29.4 to 29.4 mV/V.

  • Eight analog input channels with simultaneous sampling.
  • Maximum acquisition rate of 10 kS/s per channel.
  • Quarter-bridge inputs for 120 Ω strain gauges.
  • Input range of -29.4 to 29.4 mV/V.
  • Spring-terminal front connections and enclosed construction.
  • Specified operating temperature range of -40 °C to 70 °C.
