A series of triangulation laser displacement sensors for
non-contact height or thickness measurement of a wide variety of materials has
been introduced by Banner
Engineering. Sheet metal, wood, ceramic, paper, plastic, rubber, foam and
baking dough are some of the materials that can be measured for quality
assurance. Results are consistently accurate, with precision ranging to the
micron level, whether the target material is shiny, dark, hard or soft.
The LH Series sensors provide precise measurement of distance, web
thickness and alignment. Applications include hot parts, machined parts,
semiconductors and PCBs, shiny or reflective parts and soft or sticky parts.
There are three models in the series, with measurement ranges of 25-35, 60-100
and 100-200 mm.
Thickness is measured by two sensors mounted at either side the
target that automatically synchronize with one another. Up to 32 sensors can be
easily combined in a mixed measurement network of multi-track displacement or
thickness sensors. A wide selection of mounting brackets and industrial
cordsets allows efficient creation of sensor networks.
The dedicated software application included with each sensor
allows easy setup and configuration for new applications. The software
accommodates data logging and monitoring for statistical process control.
Output communication is via simultaneous 4-20 mA (16 bit D/A) and RS-485 serial
Measurement rates can be set to adjust based on target color and
condition, or locked for applications requiring a constant sampling speed. The
sensors are IP-67 rated for use in harsh environments. No external controller
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team Ł100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
