Wilcoxon Research, Germantown, MD, offers the iT230 Intelligent Transmitter signal conditioning module that lets you mount a velocity sensor to a machine's bearing case, and obtain machine vibration information in terms of displacement. The module converts vibration sensor signals to proportional 4–20 mA output for use in existing PLC/DCS networks; raw velocity vibration data are also available from a BNC connector on the front of the module. The device outputs 4–20 mA data in terms of rms, peak, true peak, and true peak-to-peak. F.S. displacements of 10 mils, 20 mils, 25 mils, and 100 mils are available; metric units are also available.
