….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

This highly competitive industry requires engineers to stay up to date with the latest innovations and procedures. The 2014 program is designed to provide value to powder & bulk solid engineers of all experience levels. Click here to view full agenda
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.
MCT466-SF is Stable & Accurate
Designed and configured for the demanding heat and wash down conditions in the food and snack food manufacturing industries. The MCT466-SF is simple to install and can be used in different stages of processing from fryer outlet to packaging.
Typical applications include:
• Potato Chips • Corn Chips • Tortillas
• Cookies • Crackers • Breakfast Cereals
• Milk Powders • Popcorn • Oil Base Flavorings
Global vs. Local Modeling for Different Products with NIR Transmitters
Near IR transmitters can be calibrated with separate channels for each product or they can utilize a global calibration. A Global calibration is easier to generate while separate calibrations for each product usually provides tighter standard errors.
Illustrated below are three different product results based on Global versus individual (local) product codes (calibrations) within a product family. The application data is for the measurement of PSA coat weight in the range of 8 to 40 GSM (grams per square meter) on polyethylene (PE) film at 25, 35, and 55 mils thickness. The chart and graphs below compare results of a local calibration for each coat weight measurement on film with various thickness versus the PSA measurement of all with a single global calibration and the impact it has on accuracy and standard error.

Accuracy: How close measurement is to target. E.g. how close a dart is to the bull’s eye. Accuracy is calculated from the Standard Deviation of Calibration Residual Values (difference between Lab and Calibrated MCT Values).
Precision: How close the subsequent dart is to initial dart for same conditions (reproducibility/repeatability).
Standard Error: Standard deviation of sample distribution for sample population mean or standard error of mean. Think standard deviation and variable depending on sample population.
Standard Deviation: How much variation from the average value. Low SD indicates data points close to mean and high SD indicates values spread out over large range of values.
Correlation Coefficient: Linear relationship between two variables, in this case Lab vs. MCT PSA mils thickness measurement. All Correlation Coefficients (CC) are 0.99 which is close to perfect at 1.0. Non-linear relationships can also be handled with NIR software technology, though not necessary in these applications. Low CC indicates a low performance expectation.
Process Sensors is showing our new MCT460-WP wood products moisture transmitter. This winter’s cold has driven the need for wood pellets and other bioenergy fuels to new heights!
Rich Harley of PSC will be participating in this Webinar on Friday, March 7 at 2 p.m. These webinars are being hosted on the Webinar Portal for Bioenergy at http://BioenergyWebinars.net. The Webinar Portal provides webinar hosting of both live and archived webinar events for a variety of relevant webinars related to bioenergy, foresty, natural resources and conservation.
The webinars hosted on the Webinar Portal are free to view and many of the webinars (both the live events and the archived recordings) provide continuing education credits for qualified participants from various professional accrediting organizations and societies.
Visit the Boienergy Webinar Portal today or view Process Sensors MCT460-Wood Products Moisture Transmitter Brochure.
Approximately 40 speakers and 70 exhibitor companies will participate in the Bioenergy Fuels & Products Conference & Expo to be held Tuesday-Wednesday, March 18-19 at the Omni Hotel at CNN Center in Atlanta, Ga. The event is expected to involve 500 industry professionals from the wood energy and fuels industries, including wood pellets, biomass power, biofuels, woody feedstock and harvesting.
We are pleased to announce that the fourth Panel & Engineered Lumber International Conference & Expo (PELICE) will be held Thursday-Friday, March 20-21, 2014 in the Grand Ballroom North of the Omni Hotel at CNN Center in Atlanta, Georgia. The PELICE event again immediately follows the Bioenergy Fuels & Products Conference & Expo, which will be held March 18-19, also in the Grand Ballroom North of the Omni Hotel. Both events are supported by Panel World and Wood Bioenergy magazines, and Georgia Research Institute.
Process Sensors will be showcasing our new MCT460-WP at both shows!
