Product Specification
| Description | Vibration Sensors RoHS | Mfr. Part # | PC420AR-20-DA |
| Model Number | PC420AR-20-DA |
The Wilcoxon PC420A-DA series offers 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 alerting users to changing conditions. The sensors feature a 4-20 mA output proportional to acceleration vibration and a dynamic signal output derived from an internal buffered amplifier, allowing for in-depth analysis. Users can select between peak equivalent, true RMS, or true peak output options to best suit their industrial requirements.
