Product Overview
A Simple On-Line Web Scanner for Fewer Products & Zones
The Process Sensors Guardian-HD Basic Web Profile Analyzer is a single-scanner system to measure moisture, coat weight, and temperature (optional) for all paper, film, and web-converting processes.
- Entry-level functionality for operators to run simple scans on multiple constituents
- Record data across 16 total measurement zones with up to 50 different recipes (products)
- Pre-programmed software with specific calibrations
- Reduce start-up times and waste by instantly identifying production inefficiencies
- Limit instances of edge curl and lay flat issues
- 5.7” touch-screen display
- Optional Ethernet IP, Modbus TCP/IP interface, or OPC server
- Rugged, sealed industrial frame and linear actuator withstands hot and humid environments
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

Learn MoreHow 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.
