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.

Some of the most common processes to benefit from the iT series are pharmaceutical, food and beverage, brewing, water and waste water, petrochemical, pulp and paper, and power generation facilities. The iT series is effective for 4-20 mA vibration monitoring of pumps, motors, fans, cooling towers, compressors, and gear boxes. Applying predictive maintenance techniques to these operations and machines can result in significant maintenance expense reductions. Moreover, trending of the overall vibration level does not require any sophisticated analysis skills. Observing a sustained increase in overall vibration usually provides enough evidence to warrant a more detailed inspection of the machine.

Features:

  • Slim 17.5 mm case
  • Reverse wiring protection
  • ESD protection
  • Front panel BNC for dynamic signal output
  • Communicates with other iT series modules through integrated communication bus
  • Dynamic signal available for portable data collectors or hard-wired online systems (terminals)
  • Units can be daisy chained, providing multiple 4-20 mA output from a single sensor
The above description encapsulates the entire product series. Specifications for individual configurations may vary depending on the selection chosen.
