Arctic icy lakes lose thickness

2014-02-03 14:10:00| Climate Ark Climate Change & Global Warming Newsfeed

BBC: The ubiquitous shallow icy lakes that dominate Alaska's Arctic coastal plain have undergone a significant change in recent decades. These lakes, many of which are no more than 3m deep, melt earlier in the season and retain open water conditions for much longer. And 20 years of satellite radar also now show that far fewer will freeze right through to the bottom in winter. The results of the space-borne survey are published in The Cryosphere. What is happening to the lakes is an example...

Laser Sensor measures thickness of coils in slitting lines.

2014-01-21 14:29:00| Industrial Newsroom - All News for Today

Used to determine thickness profile of individual metal strips in slitting lines, thicknessCONTROL MTS 8201.LLT O-frame measurement system uses two laser triangulation profile sensors to perform alloy-independent measurements with accuracy to few micrometres. Laser line sensor addresses specific measurement tasks, including channelled sheets and thickness of sandwich plates made from non-homogeneous materials. Non-contact thickness measurements are performed continuously. This story is related to the following:Laser Sensors | Thickness Measuring & Testing Instruments

Thickness Measurement System offers multi-layer capabilities.

2013-12-17 14:31:32| Industrial Newsroom - All News for Today

Non-contact, non-destructive, self-calibrating OptiGauge MLS™ can measure each translucent coating in object up to 20 layers thick; thickness of individual layers and total overall thickness is calculated automatically. Selection of available optical probes can direct 1,310 nm IR light from LED through transparent, translucent, or colored materials, and automation eliminates opportunity for operator error. Measurements deliver sub-micron accuracy for objects 12 µm to 50 mm thick. This story is related to the following:Thickness Measurement Equipment | Thickness Measuring & Testing Instruments
