Part of its 600 series of dynamic signal analyzers, the IOtech USB-based 672u is a 20-channel vibration analyzer. The device is suitable for large channel-count applications including machine condition monitoring, rotating machine analysis, predictive maintenance, and modal analysis. The 672u's 20 input channels have direct-integrated electronic piezoelectric (IEPE) support. Each of the 20 analog inputs features a dedicated 24-bit delta sigma analog-to-digital converter for resolution and accuracy. The 600 series supports a variety of analog input types, including accelerometer, velometer, proximity probe, microphone, tachometer, or other voltage input. The 672u is compatible with IOtech’s eZ-series software for real-time vibration analysis.
