SENSORS: The U003 from Innovative Solutions is a compact and low-cost liquid level switch that uses ultrasonic technology to detect the presence of fluid between two piezoelectric crystals sealed within the sensor gap.
The all 316 stainless steel, all solid-state U003 has no moving parts, may be mounted vertically or horizontally, and provides a simple and reliable alternative to float type level controls. It mounts with a standard ¾-inch NPT fitting (optional threaded connections or flanges also available) never needs calibration, can be provided with actuation lengths up to 100 inches from the mount and is available with an NPT male conduit connection, NEMA enclosure or other connector options.
The U003 is offered with a standard current shift output, (8mA “dry”, 16mA “wet”) or a SPDT relay, 0.5A output. The 1-inch diameter stainless probe is easy to clean, fits easily into confined spaces in any orientation and can operate in system pressures up to 800psig.
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 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.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
