Features

  • Easy calibration, operation, and standardization
  • Rugged, sealed industrial frame and linear actuator withstands hot and humid environments common with paper and converting processes
  • Automatic edge detection senses roll width to streamline set-up processes, and realigns to accommodate web drift
  • Configurations available to monitor and control multiple Guardian-HD systems simultaneously
  • Easily connect to closed-loop control systems or local alarms

Benefits

  • Minimize edge curl and lay flat issues with 100% real-time inspection of moisture, coat weight, thickness, and temperature of converting lines
  • Decrease manual start-up times by 20%, eliminating the need for time-consuming lab testing and adjustments
  • Each system can be customized to the width of the web, along with the ability to position the NIR sensor wherever it is needed

Applications

Rugged NIR Scanning for a Complete Zoned Web

Moisture and coat weight measurements can be made on many substrates including paper, film, foil, textiles, release liners, tags, tapes and labels.

The Guardian-HD 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)
  • Moisture and coatings on paper webs
  • Thickness of hot melts
  • Thickness of pressure sensitive adhesives
  • Thickness of water-based adhesives
  • Paper pulp
  • Plastic film thickness
  • Biax film
  • PVB & EVA film
  • Exit and inlet dryer moisture measurement
  • Cast film
  • Coated abrasives
  • Wax coatings
  • Extrusion coatings on paper/foil
  • Moisture in corrugated board

How It Works

Entry-Level Functionality for Operators to Scan Multiple Constituents

The Guardian-HD Series features an NIR sensor that is connected to a traversing frame to continually scan the full-width of a web profile for moisture and coat weight parameters. Real-time data is presented on an easy-to-understand touchscreen display for cross direction web profiling, lane and machine direction measurements. In some configurations, larger displays with Windows®-based software are available for monitoring multiple line profiles at a single central console.

All Guardian-HD Series configurations allow for USB data-logging with the ability to export to .csv, .xml or .txt file formats.

Each Guardian-HD frame is custom-built for its specific application, and the analysis software can be pre-programmed for specific recipe codes for the material it is analyzing. The NIR sensor can also be positioned in different ways to accommodate reflective surfaces (common with wet-end coating applications) as well as horizontal, vertical, and under-side scanning.
