Rapid, continuous product analysis is critical for all paper, film and converting processes. The Guardian Web Profiling System is designed for reliable determination of coat weight, moisture and film thickness for quick return on investment in diverse converting applications.
Maintain uniform web profile, reduce waste and improve quality
The Guardian supports process optimization by accurately measuring moisture and coating thickness, providing a complete zoned web profile. Reduce start-up times and waste by visually identifying production inefficiencies using the PSC proprietary software.
Guardian systems are accurate, fast, reliable & low maintenance. They provide a non-contact, non-destructive on-line measurement and are unaffected by relative humidity, changes in product temperature, ambient light and temperature. Guardian Near Infrared (NIR) Systems have many other benefits and advantages:
- Minimize edge curl and lay flat issues
- Easily connect to closed loop control systems or local alarms
- Decrease manual start-up times by up to 20% by eliminating the need for time consuming lab testing and adjustments
- Easy calibration, operation & standardization
Reliable performance for converting applications
Moisture and coat weight measurements can be made on many substrates including paper, film, foil, textiles, release liners, tags, tapes and labels. The Guardian Web Profiling System is commonly used in the following applications:
- Hot Melt & Film Thickness
- Wet End Water Based Coat Weight
- Dry End Organic Coat Weight
- Exit and Inlet Dryer Moisture
- Re-Moisturizers (LAS, Steam Curtains and Water Decks)
