Juno Blizzard Hits Boston and PSC Hard – Office Closed Today!

Snowstorm-21Winter Storm Juno was pounding New England with moderate to heavy snow, high winds and coastal flooding Tuesday morning.

Parts of Connecticut, Maine, Massachusetts, New Hampshire, New York and Rhode Island have seen more than a foot of snow.

Snow amounts in New York have ranged from 7.8 inches at Central Park in New York City to more than 28 inches in eastern Long Island. La Guardia airport in New York City has seen 11 inches.

In Massachusetts, up to 26.2 inches of snow has been measured in Shrewsbury, while Boston endured heavy snow and wind gusts over 30 mph from 1 a.m. to 9 a.m. ET. Wind gusts in eastern Massachusetts have topped 70 mph and coastal flooding has closed some roads.

Thunder snow was reported in coastal portions of Rhode Island and Massachusetts late Monday night and early Tuesday.

Happy Ice City from Process Sensors for New Year’s!

Process Sensors wishes to Gift You with a view of the Annual Harbin Ice Festival in China!  An incredible City of Ice!

Harbin Ice Festival 010415

 

The festival originated in Harbin’s traditional ice lantern show and garden party that takes place in winter, which began in 1963. It was interrupted for a number of years during the Cultural Revolution, but has since been resumed when an annual event at Zhaolin Park was annnounced on January 5 in 1985.

In 2001, the Harbin Ice Festival was merged with Heilongjiang‘s International Ski Festival and got its new formal name, the Harbin International Ice and Snow Sculpture Festival.

In 2007, the festival featured a Canadian themed sculpture, in memoriam of Canadian doctor Norman Bethune. It was awarded a Guinness Record for the world’s largest snow sculpture: 250 metres long, 28 feet (8.5 m) high, using over 13,000 cubic metres of snow. The composition consisted of two parts: the “Niagara Falls” and the “crossing the Bering Strait” (the latter depicting the migration of the First Nations).

In 2014, the festival celebrated its 30th anniversary with the theme “50-Year Ice Snow, Charming Harbin”. Various fairs, competitions and expos were held from 20 December 2013 to February 2014.[2]

The annual Harbin International Ice and Snow Sculpture Festival (Chinese: ????????; pinyinH?’?rb?n Guójì B?ngxu? Jié) is an annual winter festival that takes place with a theme in HarbinHeilongjiangChina, and now is the largest ice and snow festival in the world. At first participants in the festival were mainly Chinese, however it has since become an international festival and competition. The festival includes the world’s biggest ice sculptures.[1]

Officially, the festival starts on January 5 and lasts one month. However, exhibits often open earlier and stay longer, weather permitting. While ice sculptures are erected throughout the city, there are two main exhibition areas:

  • Sun Island is a recreational area on the opposite side of the Songhua River from the city, which features an expo of enormous snow sculptures.
  • Ice and Snow World is an area open during at night which features illuminated full size buildings made from blocks of 2–3′ thick ice taken directly from the Songhua River. At first China celebrated it then Harbin took over.

During the festival, there are ice lantern park touring activities held in many parks in the city. Winter activities during the festival include Yabuli alpine skiing, winter-swimming in the Songhua River, and the ice-lantern exhibition in Zhaolin Garden.

Harbin is located in Northeast China and receives cold winter wind from Siberia. The average temperature in summer is 21.2 °C (70.2 °F), and –16.8 °C (1.8 °F) in winter. Annual lows of -35 °C (–31 °F) are not uncommon.

Pack Expo Tight Rope

Pack Expo was a great show with Eduardo Villasenor and Luis Rivera of J.A Diaz, our Mexican Distributor, and ThermoCense, our Chicago area representatives joining us.  We visited with many existing customers with new projects and new customers.  Great Show for us!

Highlight Sunday night was Nick Wallenda’s tight rope walk a few blocks from the convention center.  Happy Friday from Process Sensors!

Calibration Check Standard

cal check

Calibration Check Standard

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.

 

Near Infrared Measurements – How Do They Work?

Light Spectrum

Light Spectrum

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.
