Product Overview
The Wilcoxon Sensing Technologies PCC420A series are loop-powered sensors designed to provide a 4-20 mA output proportional to vibration, enabling continuous trending of overall machine vibration. This data assists in alerting users to changing machine conditions and prioritizing maintenance needs. The sensors offer a choice between True RMS or calculated peak acceleration output, allowing for selection based on specific requirements. Their compact housing is suitable for applications with height restrictions, and they can be easily integrated into existing process control systems. Manufactured in an approved ISO 9001 facility, these sensors are designed for reliability and performance in industrial environments.
