Wilcoxon Research, Gaithersburg, MD, a leading supplier of quality vibration sensors and sensor networks, has expanded its line of 4-20 mA loop powered vibration transmitters. Wilcoxon's Intelligent Transmitter (iT) Series allows customers to select from a full line of features at the time of order, including:

• acceleration, velocity or displacement measurements
• rms, peak, true peak and peak-to-peak detection
• a selectable full scale that can be specified in English or metric units

"The iT Series allows maintenance professionals to create a custom vibration monitoring center," says Tom Smith, Director of Sales & Marketing at Wilcoxon Research. "Each iT Transmitter is custom-built to user specifications, and we are also expanding our options for online monitoring and data trending."

The Intelligent Transmitter, a vibration transmitter, converts vibration sensor signals to proportional 4-20 mA output for use in existing PLC/DCS networks, and can operate at much lower or much higher frequencies than typical ISO-standard 4-20 mA sensors.

The iT Transmitter now measures displacement, in addition to acceleration and velocity, which have been available since it was released a year ago. Displacement measurements indicate overall movement. A displacement transmitter is ideal for applications that measure absolute position, such as shaft movement within a bearing race. Transmitters that measure velocity are most common for measuring overall machine health, and acceleration measurements are best for high frequency diagnostics. All three are now available with the iT Series.

Output of 4-20 mA data is offered in terms of r.m.s., peak, and now also in Wilcoxon's exclusive true peak and true peak-to-peak. True peak detection is ideal for measuring short duration vibration, when it is most important to capture and hold maximum absolute instantaneous impacts. True peak-to-peak detection is designed for use with displacement measurements, which captures and holds the maximum total vibration. Peak and r.m.s. detection are best for general machine health monitoring, when overall vibration is measured.

Customers have always been able to order the iT Transmitter with a full scale to fit their application. Now it can be ordered with a configuration appropriate for the many customers in the US and internationally that employ metric units. The iT Transmitter can be configured for full-scale selection in standard or metric units. Maintenance professionals can order the Intelligent Transmitter with a custom frequency band to meet specific requirements based upon their intended use. The programmed frequency band has a 2-pole high-pass filter and an 8-pole low-pass filter, operates at superior low-noise performance, and measures sensor BOV to monitor sensor performance. Combined, these features ensure the most accurate readings of machinery vibration.

The iT Series is an extensive line of 4-20 mA vibration monitoring units which make cost-effective online vibration monitoring easy. Customizable transmitter modules can connect to a PLC or DCS for vibration trending at a fraction of the cost of traditional systems. The series includes the iT Alarm with three programmable relays to monitor set point limits. Alone or in conjunction with a PLC or DCS, the iT Alarm provides immediate notification if a machine's vibrations exceed acceptable levels. The iT Communication Module greatly simplifies data acquisition and analysis by sending digital vibration data directly to your computer via an RS232 serial port. Using Wilcoxon's free VibeLink™ software, economical online monitoring is available from any desktop.

Wilcoxon's reputation for industry-leading quality and functionality is exemplified in the multitude of features on the iT Series. Additional features include:

• Wilcoxon products are convenient to use and easy to install in industrial environments
• The iT Series is among the narrowest transmitters available and its modular plugs simplify installation in confined spaces
• Multiple DIN-rail units automatically exchange data and power without external wiring
• Raw dynamic output is available on each transmitter via hard wire monitoring as well as a BNC connector for walk-around measuring
• Status indicators appear on the front, and custom-programmed requirements are displayed on the side of the transmitter
• All versions of the iT Transmitter are CE Certified

Wilcoxon offers DIN enclosures, power supplies, accessories and custom cables to compliment the iT Series Wilcoxon's Intelligent Transmitter is suited to Condition Based Monitoring in a variety of applications including: fans, motors, blowers, compressors, chillers, gearboxes, pumps, reciprocating compressors, cooling towers, mixers, gas/steam turbines and centrifuges.
