ELECTRONICS: Williamson Corp’s Gold Series single-wavelength infrared temperature sensors provide up to ¼ percent of reading measurement accuracy for monitoring and controlling product quality and process productivity. Configurable for a multitude of applications where devices such as thermocouples and RTDs would be inaccurate, too slow, or difficult to use, they measure a target’s temperature without contact, making them ideal for high-temperature environments, moving targets, and fast response times.Available in a complete range of precisely selected short, long, and specialty wavelengths, Gold Series infrared sensors measure the amount of infrared energy emitted by an object’s surface, then convert this signal into a temperature value between -40 and 4,500F (between -40 and 2,475C). Each model can be used as a stand-alone transmitter with a choice of inputs, outputs and alarms. For more advanced capabilities, interface modules, PID controllers and PC software programs are available.
Sample applications for Gold Series sensors include metal forging and milling; metallic mold and dies; heat treating; boilers; thermal reactors; incinerators; kilns; flares; and the processing of paper, rubber, textiles, plastics, ceramics, and glass.
When in the stand-alone mode, the local interface of a Gold Series sensor is used to display the temperature and adjust sensor settings from an intuitive text-based menu. An optional analog input is available for remote emissivity and alarm adjustments. Units are compatible with bidirectional RS232 and RS485 communications as well as 4-20 mA and voltage-sensor outputs, which may be programmed with a choice of up to five different measured parameters. An addressable networking option for most of the industry’s bus protocols will be released in the spring of 2010.
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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
