Happy Friday from Process Sensors!
Please take a look at our various applications, upcoming events and company news.
Sunday May 11th is Mother’s Day! Anna Jarvis helped found Mother’s Day and often emphasized that hand written notes from children to their mothers was much more important than store bought cards and chocolates. Happy Mother’s Day from Process Sensors!
….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 MCT460-SS Nova Series of Near Infrared (NIR) Analyzers offer unparalleled performance/price ratios in all applications. Hazardous and challenging environments that others stay away from are routine for us. While some recommend high air purges, we recommend a 3-5 psig across the window in rough situations. Anything higher causes a turbulent air flow forcing particles onto the measurement lens and blocking signal and impacting signal/noise and accurate readings. Others sometimes want a high flow, quick demo and exit. We’re there to make your installation a success.
We are all deeply saddened at the terrible loss of our beloved friend and co-worker Charlie Kent. Charlie passed away at his home on Saturday January 4th, 2014. Charlie worked for PSC for over 13 years. He loved taking Lola (company mascot) for walks, playing his guitar, gaming on his computer and collecting and building military models. Charlie was a very loved family member and an important part of our team here at PSC. We will miss you Charlie. Attached are the directions to the Funeral home below.
Funeral services will be held on Tues., Jan. 7 at 7:00 pm in Jackman Funeral Home, 7 Mechanic St., Douglas. Calling hours at the funeral home are Tues., Jan. 7 from 4-7 pm. In lieu of flowers, donations in Charlie’s memory may be made to the Wounded Warrior Project, PO Box 758517, Topeka, KS 66675 or www.woundedwarriorproject.
Process Sensors values you our customers and our team works to meet your needs! Please contact in this new year to help with your projects. Season Greetings from Process Sensors!
Near Infrared (NIR) measurements are based on specific absorption bands in the electromagnetic spectrum between 800 and 2500 nanometers (nm). While full spectrum analyzers may utilize the entire spectrum and multivariate mathematical treatments such as Principal Component Regression (PCR), Partial Least Squares (PLS) or neural networks, photometers use “slices” of the spectrum that correspond to specific molecular overtones and associated vibrational absorptions.
Photometers utilize narrow band pass interference filters that have a specified band width typically 50 nm wide, though the band width is sometimes application dependent. The NIR has broad bands as opposed to the sharp peaks in the Infrared region. Common bonds are O-H (1940 and 1420 nm) in water, C-H (2340 nm) in organics and oils and N-H in proteins. The absorbance level at these specific wavelengths is proportional to the quantity of the constituent to be measured.
Shining light at these wavelengths causes the corresponding chemical bond to vibrate and absorb energy. Think of different sections of a stadium crowd called upon to shout and jump when their section is highlighted on the stadium Jumbotron.
Photometers compare near infrared energies at measure and reference wavelengths and are typically calibrated with a simple linear regression analysis though non-linear algorithms can be employed for specialized applications or for wide dynamic ranges. Photometers are easy to install and maintain and they are used in process, at-line and in the laboratory for rapid product analysis. Typical applications are found in the food, pharmaceutical, tobacco, converting, chemical, mineral and wood processing industries.
