PC420A Series Intrinsically-Safe 4-20 mA Loop-Powered Sensor

Wilcoxon’s 4-20 mA vibration sensors incorporate an accelerometer, data acquisition circuitry, and vibration transmitter in a rugged industrial housing. They provide 4-20 mA output signal proportional to the overall vibration level. The 4-20 mA output is commonly accepted by process control systems such as a PLC, DCS or SCADA system, for effective continuous vibration monitoring. If you already have a process control system that accepts 4-20 mA inputs - like a PLC or DCS network - you are already taking data points on pressure, temperature, or maybe flow. You can send vibration data to your PLC or DCS as well. By connecting into process control systems, you are able to perform simplified condition based maintenance on machinery without the investment and learning curve associated with traditional vibration monitoring systems. 

The PC420A sensors are classifed for usage in Class I Division 1/Zone 0/1 locations where ignitable concentrations of flammable gases, vapors or liquids are present continuously under normal operating conditions.
