The high-performance PXI platform is recommended for measuring proximity with Eddy current probes. PXI modules for proximity sensors have input voltages up to ±42 V with simultaneously sampled inputs at up to 204.8 kS/s. Modules include software and hardware needed to make precision measurements with transducers that have very large dynamic ranges, such as sound, vibration, and proximity sensors.

NI CompactDAQ is the best solution for portable and low-cost proximity measurements. The NI 9229 module for proximity measurements provides ±60 V input range, a dynamic range of 128 dB, antialias filtering, channel-to-channel isolation, 50 kS/s/ch simultaneously sampled. This module, designed to be high-speed and accurate, is also an effective general-purpose analog module because of its resolution, sample rate, and input range.
