The intelligent transmitter (iT) series from Wilcoxon is a complete family of 4-20 mA units providing signal conditioning for simplified online vibration monitoring. The iT series lowers the total cost of condition monitoring and predictive maintenance programs deployed by industrial, commercial and municipal facilities. 

Each transmitter is custom-designed for individual applications. High- and low-pass filters can also be selected by the user. iT transmitters support accelerometers and piezovelocity transducers and can be configured to output 4-20 mA signal proportional to acceleration, velocity or displacement. The 4-20 mA output can be sent directly to the facility’s existing PLC or DCS for cost-effective continuous vibration monitoring. 

iT vibration transmitter modules operate from a 24 Volt DC (nominal) power supply, accepting input directly from IEPE sensors and processing the signal to produce a 4-20 mA loop current proportional to the overall in-band vibration. The input dynamic vibration signal is buffered and presented as an output at the BNC connector and on one set of terminals.
