Identifying suppliers - search the Design News articles archives. Lots of times there are articles on devices - from sensors to microcontrollers and more, that show good comparisons with background information.
Q. What factors I need to consider to choose, for example, a pressure sensor for a medical application?, Can I choose any sensor from the market or it has to be special?. Thank you.
Sensing in medical applications can pose a few callenges. The first level is whether the sensing is external or internal. Obviously thermometers can address internal (but not invivo) measurements rather easily. Internal blood pressure measurements have specifcations that have been developed. Some sensor suppliers caution against the use of their products in medical applications.
Since you are checking pressure drop across a filter, what is the system pressure.
This would determin the common mode presure the sensor must tolerate.
Good point. I should have stated air filtering in a computer system. If this was a high pressure water flow application, the common mode pressure would certianly been a top level cosnideration and it would have added packaing complexity to the decision. For air filter monitoring, many pressure sensor suppliers address this type of application and the comon mode pressure is not normally an issue.
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.
