Provides dynamic signal acquisition in rugged environments. FieldDAQ™ devices are dust- and water-resistant and offer TSN technology for simplified distribution.
The Sound and Vibration Input Device for FieldDAQ incorporates software-selectable AC/DC coupling, integrated electronic piezoelectric (IEPE) open/short detection, IEPE signal conditioning, and TEDS support. The input channels simultaneously measure signals, and each channel has built-in anti-aliasing filters that automatically adjust to your sample rate. The device is IP65/IP67 dust- and water-resistant, can operate in -40 °C to 85 °C environments, and can sustain 100 g shock and 10 g RMS vibration. Additionally, the device can be used for test cell and outdoor environments, and can be used stand-alone or as an extension of a CompactDAQ, CompactRIO, or PXI system. The Sound and Vibration Device includes the NI-DAQmx driver and configuration utility that simplify configuration and measurements. NI-DAQmx supports NI programming environments as well as Python, ANSI C, C#.NET, and MathWorks MATLAB® software.
