Web Profiling System—Guardian-HD

Process Sensors Corporation has introduced a web profiling system called the Guardian-HD. The system supports process optimization by precisely quantifying moisture and coating thickness, offering a comprehensive zoned web profile of wide or narrow webs.

By visually detecting production inefficiencies, users can reduce start-up times and waste and achieve a rapid return on investment. In addition, intuitive graphical displays in the Guardian-HD offer crucial production insight for instant detection of out-of-specification products.

Reliable Performance for Challenging Converting Applications

The latest Guardian-HD web profiling system has been specifically developed to work reliably in complex conditions that are often found in paper and converting processes with the latest robust linear actuator and a sealed industrial frame.

Coat weight and moisture can be measured on several substrates, such as film, paper, labels, tapes, tags, release liners, and textiles. The Guardian-HD web profiling system is typically employed in the following applications:

  • Dry end organic coat weight
  • Wet end water-based coat weight
  • Hot melt and film thickness
  • Re-moisturizers (water decks, steam curtains, and LAS)
  • Exit and inlet dryer moisture

Reduce Waste, Improve Quality, and Maintain Consistent Web Profile

The Guardian-HD systems are fast, precise, reliable, and require only minimal maintenance. The systems offer a non-destructive, non-contact, on-line measurement and are not affected by variations in product temperature, relative humidity, temperature, and ambient light.

The Guardian-HD Near Infrared (NIR) systems also provide the following benefits and advantages:

  • Easily link to local alarms or closed-loop control systems
  • Minimize lay flat and edge curl problems
  • Streamlined calibration, operation, and standardization
  • Reduce manual start-up times by around 20% by preventing the requirement for time-intensive laboratory testing and modifications
  • NIR technology is different from X-ray systems and does not pose a health hazard to employees
  • Output options include 4-20 mA and popular communication protocols

Choose Guardian-HD—Elite or Essential

All Guardian-HD systems come with a local touchscreen display, an NIR smart sensor, and an industrial scanning frame for cross-direction web profiling.
