Rapid and continuous product analysis is crucial for all paper, film and converting processes to ensure consistent high-quality products. Improper moisture control can lead to edge curl and lay flat issues. Coat weight and film thickness directly relate to end product quality. The Guardian-HD accurately measures moisture and coating thickness on-line, providing a zoned web profile across narrow or wide webs for 100% real-time inspection of converting lines.
REDUCE WASTE AND IMPROVE QUALITY
Reduce start-up times and waste by instantly identifying production inefficiencies for quick return on investment. Real-time data eliminates the need for time consuming lab testing and adjustment. Intuitive graphical displays provide critical production insight for rapid identification of out of specification product.
RELIABLE PERFORMANCE
The Guardian-HD Web Profiling Systems are designed for reliable operation in the challenging conditions found in paper and converting applications with a sealed industrial frame and powerful linear actuator. They provide a non-contact, non-destructive on-line measurement and are unaffected by relative humidity, changes in product temperature, ambient light and elevated temperatures. Unlike nuclear and X-ray systems, NIR does not require costly regulation compliance and safety certification.
EASILY INTEGRATED TO LOCAL SYSTEMS
The Guardian HD Web Profiling systems are easily integrated into local plant PLC for closed loop control via 3 4-20 mA analog outputs and optional databus interfaces for standard communication protocols. Optional stack light alarms and output relays ensure that out of specification production is communicated instantly for prompt adjustment and minimal waste.
