Product Overview
The Wilcoxon PC420A-DA series are dual output, loop-powered acceleration sensors designed for continuous 24/7 monitoring of overall machine vibration. These sensors integrate easily into existing PLC, DCS, or SCADA systems, providing dynamic signal output for in-depth analysis and trending. They alert users to changing machine conditions, aiding in maintenance prioritization. Available with choice of peak equivalent, true RMS, or true peak output, the 4-20 mA output is proportional to acceleration vibration, while the dynamic output signal is derived from an internal buffered amplifier. Manufactured in an approved ISO 9001 facility.
