Product Overview
The Wilcoxon PC420A-DA series offers dual output, loop-powered acceleration sensors with dynamic vibration output. These sensors are designed for 24/7 monitoring of overall machine vibration, enabling continuous trending and alerting users to changing machine conditions. They integrate easily into existing PLC, DCS, or SCADA systems. The PC420A-DA series provides a choice of peak equivalent, true RMS, or true peak output, allowing selection based on specific industrial requirements. The 4-20 mA output is proportional to acceleration vibration, and the dynamic output signal, derived from an internal buffered amplifier, requires 4-20 mA loop power. These sensors are manufactured in an approved ISO 9001 facility.
