Loop powered dual output acceleration sensor Amphenol PC420AP-20-DA with dynamic vibration signal output
Product Overview
The Wilcoxon PC420A-DA series represents dual output, loop-powered acceleration sensors designed for dynamic vibration monitoring. These sensors provide a 4-20 mA output proportional to acceleration vibration, enabling continuous trending and early detection of changing machine conditions for proactive maintenance. The dynamic signal output, derived from an internal buffered amplifier, allows for in-depth analysis and easy integration into existing process control systems like PLCs, DCS, or SCADA. Users can select 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 suitable for 24/7 monitoring of overall machine vibration.
