Process Sensors Guardian Cross Direction Web Profile System can be as simple and inexpensive as an automatic scanning frame with 12” frame mounted Operator Interface (OI) for profile display and controls.
The Guardian Profile System can also connect to a 19” Display at the Central Console or a 55” or larger display for multiple scanners and measurements integrated into a single distributed system. The Guardian System can be operated manually or via a Human Machine Interface (HMI).
In packaging, converting, assembly, bookbinding, nonwovens, footwear and many other markets, hot melt glues and adhesives offer a critical advantage: fast processing. Unlike water-based or solvent-based adhesives, hot melt adhesives do not require drying. Hot melts begin bonding almost immediately after application, as they cool down to their solidification point. This fast solidification is ideal for use on highly automated manufacturing lines that require rapid bond formation. Glue pillow manufacturers report increasing demand as customers move from drums to returnable/recyclable containers. While the moisture contained within the glue pillow is very low, problems occur when surface moisture on the pillow exterior accumulates during the manufacturing process prior to packaging for shipment.
The Near IR moisture transmitter is mounted 8-18” above the conveyor where it scans product only, with few gaps between pillows. An angle wedge or diverter may be installed that insures constant glue pillow product under the transmitter without slowing the overall product flow. The intention of measuring moisture on the glue pillow is not to determine absolute moisture but to determine when the surface moisture is within acceptable limits.
Samples of low, acceptable and high moistures are presented to the transmitter and it is scaled appropriately. For example, low surface moisture is assigned a value of 0, acceptable 3 and high moisture 5. The MCT460 features a 5.7” Operator Interface Display, 4-20 mA proportional analog output and optional Ethernet connection.
….the Boston Marathon was a booming, positive success story….36,000 runners…a million observers (how that is determined, I have no idea)…picture perfect weather day…PSC is located in Milford MA about 3 miles from the Boston Marathon Start in Hopkinton MA!
Congratulations to American Meb Keflezighi who is the first American man to win the Boston Marathon since Greg Meyer in 1983, and to Rita Jeptoo who set a course record with a time of 2:18.57.
A Great Day for Boston, America and the World Celebrating Sportsmanship and Freedom!
The check standard is a stability check and validation that analyzer performance hasn’t changed. After the unit has been calibrated, you go to a pre-selected “Cal Check” product channel and record the high value and low value. The high and low value for the check standard should always be between +/- 0.1 to 0.2 of original cal check values.
There are three immediate benefits for the standards. First is that they are stable and don’t change. Samples of known moisture, oil, coat weight or other parameter are required for calibration. Typically 3-5 samples throughout the range of interest. Calibration is easy. To check calibration after start up, you can’t use retained samples because they aren’t stable and degrade. The Cal Check standards are stable to check analyzer stability.
Secondly, most customers want to routinely validate all of their analyzers performance. The Cal Check standards allow for periodic validation. Most customers who have used our analyzers for a long time check every 3 months. Newer users usually check once a week, then once a month etc. It’s a confidence booster.
Thirdly, if you get an usually high or low measurement you can quickly check whether the analyzer has changed or sample or process. And make necessary adjustments. Calibration Check Standards are a valuable tool in diagnostics.
Process Sensors will Exhibit at Booth #3006 May 6-8 Rosemont

The International Powder & Bulk Solids Conference is your exclusive opportunity to obtain a years’ worth of educational content and networking in just three days.
New Format – Shortened 1.5-hour sessions to expand your education menu each day!
Proficiency Indicators – The core technical training we have always featured now has easy indicators to tell you whether it is Fundamental (F) or Advanced (A) education so that you can determine what level of training is right for you.
Enhanced International Presence – It’s the International Powder Show, so we’ve heightened the international representation on the speaking faculty to give you access to more experts from around the globe including Australia, Germany, India, Israel, Japan, Scotland, Spain, and United Kingdom.
The Guardian Scanning Frame System Parameters allows the operator to quickly view scanner and transmitter diagnostics. Scanner diagnostics reveal automatic edge detection, current and average moisture or coat weight measurements and web position.
