This new series of RMS current transducers offer accuracy over a 20Hz-2KHz range. Available in 14 current ranges from 2A to 250A, they have an accuracy of 0.25 percent over a temperature range of -40 to 85C (-40 to 185F). They also have a wide voltage power range from 12V to 32V, and a current signal from 4mAdc to 20mAdc. They protect against reverse polarity and overload currents of up to 500A, plus a load resistance range from 0 to 300. They have an epoxy coating on the internal circuitry for insulation and protection from moisture and contaminants. They come built into a molded plastic, 94V-O flammability-rated case. Storage temperature is -55 to 125C (-67 to 257F)They also come with a five-terminal barrier and a 0.75-inch pass-through hole. A six-pin connector and nine-pin D-Sub connector are also available.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
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.
