PC420AR-10-EX 4-20 mA-Vibrationsaufnehmer

Stromschleifengespeister Sensor mit Peak-, RMS- oder True-Peak-Erkennung für den explosionsgeschützen Bereich

About the PC420AR-10-EX

4-20 mA vibration sensors incorporate an accelerometer, 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 acceleration 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 acceleration-output sensor gives a signal with increased sensitivity to higher frequencies which can help indicate bearing wear and gear mesh conditions. 4-20 mA sensors are specified by their full scale values, where a “-10” sensor is designed with a full scale range of 10 g’s equivalent to 20 mA. By trending overall acceleration, changes can be monitored and when a predetermined increase is reached, an informed decision to shut down machinery can be made.
