Semiconductor pressure sensors have limitations when used in hot environments. One of the most debilitating limitations is their susceptibility to electromagnetic interference. A new self-calibrated interfermetric intensity-based (SCIIB) sensor developed at the Virginia Tech Photonic Laboratory (VTPI) is immune to electromagnetic interference. It also resists chemical corrosion and withstands temperature above 482C—the temperature limit of sensors used in jet engines, power plants, and other hot environments. Sensors placed in a jet engine are expected to monitor sound pressure waves and warn the pilot about potential engine problems. The sensors are made using the fibers of a single crystal sapphire. The U.S. Department of Energy awarded VTPI's partner, Oak Ridge National Laboratory, with funding to collaborate on the project and commercialize the sensors. Oak Ridge National Lab has a sapphire material processing and fabrication facility. For information call (540) 231-4363.
The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
Advantech has launched a new series of motion-control I/O modules to meet the increased demands that come with more distributed industrial systems that require control of a growing number of axes and devices.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
