PC420V-EX Series

Explosion-proof, velocity loop powered sensor

Wilcoxon’s 4-20 mA vibration sensors incorporate a velocity transducer, data acquisition circuitry, and vibration transmitter in a rugged industrial housing. The explosion-proof sensor provides a 4-20 mA output signal proportional to the overall velocity level. The 4-20 mA output is commonly accepted by process control systems including PLC, DCS or SCADA for cost-effective continuous vibration monitoring. Simplified condition based maintenance can be performed on machinery without the investment and learning curve associated with traditional vibration monitoring systems.
The velocity-output sensor is most suitable for rotating machinery which runs in the 600-3600 RPM (10-60 Hz) range due to its increased sensitivity to low frequency vibration. 4-20 mA sensors are specified by their full scale values, where a “-10” sensor is designed with a full scale range of 1.0 ips (inch per second) equivalent to 20 mA. By trending overall velocity, changes can be monitored and when a predetermined increase is reached, an informed decision to shut down machinery can be made.
