Product Overview
The Wilcoxon PC420A-DA series offers dual output, loop-powered acceleration sensors designed for continuous machine vibration monitoring. These sensors provide a 4-20 mA output proportional to acceleration vibration, integrating seamlessly into existing PLC, DCS, or SCADA systems for 24/7 trending and early detection of changing machine conditions. The dynamic signal output, derived from an internal buffered amplifier, allows for in-depth analysis. Users can choose between peak equivalent, true RMS, or true peak output to best suit their industrial requirements. Manufactured in an approved ISO 9001 facility, these sensors are ideal for guiding maintenance prioritization and ensuring operational efficiency.
