cPAT
In Process Color Measurement. Control In Real-time
cPAT aims to enhance the efficiency and quality of manufacturing and minimize costs through the implementation of best practices and tools for automation. It streamlines the production color quality control process by shifting from manual, time-based measurements to real-time monitoring, automated color control and defect containment.
Online, real-time color measurement and monitoring
Touch screen PLC with easy to set up and operator friendly color-control software
Automated closed-loop color control
Outputs for downstream defect containment
Historic data logging and storage for retrieval via USB or remotely on a network by FTP
Process variables charted in real-time with 100 scans of data storage for on screen viewing
Calibration reminders automatically displayed based on number of scans and time since last calibration
