The Guardian Web Profile Scanning Frame System consists of an MCT360 NIR Transmitter, industrial scanning frame with built-in position encoder, industrial PC and easy to operate software. Moisture, water based coatings, organic coatings and film thickness can be measured. These measurements are mapped across the web to provide a zoned web profile on paper, film, foil or metal. The Guardian Cross Direction Web Profile software package allows multiple profiles and alarms on a single display. The flat screen display size and enclosure can be specified for pedestal, wall or console mount. PSC supplies startup, calibration and validation services.
ICE Europe March 19-21 Munich Stand 754. ICE is the International Converting Exhibition. We have posted profile, products, and press releases on the ICE Exhibitor Website. Look for us under Exhibitors P for Process Sensors!
Guardian Cross Direction Web Profile System Makes Coat Weight Measurement Easy
The Guardian System utilizes the MCT-360 Coat Weight Transmitter to measure water based coatings. The water in the coating absorbs at 1.94 microns and allows easy measurement of the coating applied to paper, nonwovens, film, foil, metal, and other substrates. The Guardian System traverses the web on an automatic scanner providing zone averages, web average measurement, and roll reports. Measurements are available in lbs./ream, GSM, mils, and other engineering parameters. Please contact us at 508.473-9901 to discuss your application today.
Steam Re-Moisturizer Control to Reduce Edge Curl & Improve Web Flatness with Guardian Cross Direction Web Moisture Profile
Steam Re-moisturizers are increasingly used to reduce edge curl and consist of a series of steam chambers across the web. These chambers typically range from four to eight inches in width and can be single or double sided depending on the application.
Upgrading your steam foil/box to automatic control speeds startup, reduces scrap, and improves Quality Control. When considering an upgrade, a few points need to be considered to maximize value. The best data to be used from the web profile is the raw data instead of the moisture profiles zone averages as they may not match up to the steam re-moisturizer zone chambers when web widths change.
The raw data needs to be parsed to match up to the chamber zones and this means that the profiler must recognize varying web widths via a recipe. The parsed data is then sent to a Programmable Logic Controller (PLC) to control each steam zone?s individual actuator valve. Instead of having operators manually enter this recipe data individually into the profiler when product widths change, it?s preferred to have the HMI (Human Machine Interface) Operator Station communicate to the profiler via Wonderware, Modbus, or other suitable protocol. This reduces the number of operator tasks and speeds product change over.
The Guardian Cross Direction Web Moisture Profile Data should also be stored separately for data archiving, typically through a separate Ethernet link.
