The Guardian Web Profile Scanning Frame System is comprised of three components.
- MCT-460 NIR Transmitter
- Automated Scanning Frame
- PC with Automated Guardian Profile Software
The MCT 460 NIR sensor is mounted on the scanner and is programmed to move continuously across the web. Both the scanner and the MCT 460communicate directly with the Guardian Profile Software.
- Maintain Uniform Web Profile
- Reduce Edge Curl and Lay Flat Issues
- Improve Quality Assurance and Control
Edge curl and lay flat issues are a problem in the label and converting industry. Uneven moisture stratification can cause shrinkage or expansion of cellulose fibers. Curled stock is a problem for printing and packaging. Coatings can also get thinner or thicker at the edges. A NIR transmitter cross directional web profile greatly helps to reduce curl or coating issues and improve process control operation.
Benefits of Near Infrared Technology
- Accurate, Fast, Reliable & Low Maintenance
- No Government Regulations
- Easy Calibration, Operation & Standardization
- Best Return On Investment
The Near Infrared (NIR) Operating Principle
The MCT transmitter shines NIR light wavelengths, selected specifically by PSC, for the measurement and application being performed, typically 1.94? for moisture or water based coatings and 2.34? for hydrocarbon depositions or film thickness. The NIR light is then directed onto the product being measured, normally a moving web and measures the returned energy to provide a calibrated display of percent moisture, GSM, #/ream or other engineering units. Additionally, IR web temperature can also be built into the MCT Nova Series Transmitter.
