Product Overview
The Wilcoxon PCC420V series sensors are loop-powered velocity sensors designed to provide a 4-20 mA output proportional to velocity vibration. This enables continuous trending of overall machine vibration, alerting users to changing machine conditions and guiding maintenance prioritization. Available in true RMS or calculated peak output options, these sensors offer compact housing for applications with height restrictions and are easily integrated into existing process control systems. They are manufactured in an approved ISO 9001 facility.
