Product Overview
The Wilcoxon PC420A-DA series are dual output, loop-powered acceleration sensors designed for continuous 24/7 machine vibration monitoring. These sensors integrate seamlessly with existing PLC, DCS, or SCADA systems, providing overall machine vibration data for trending and proactive maintenance. Offering a choice of peak equivalent, true RMS, or true peak output, the PC420A-DA series allows users to select the sensor best suited for their industrial requirements. The 4-20 mA output is proportional to acceleration vibration, while the dynamic output signal, derived from an internal buffered amplifier, enables in-depth analysis of vibration data. Manufactured in an approved ISO 9001 facility, these sensors are built for demanding industrial environments.
