I agree. This is a very nice article. I would like to add that in selecting thin film or wire wounds the engineer needs to factor in installation harness length . Thin films are driven by microamps, whereas wire wounds are driven by milliamps. Therefore, the signal to noise ratios need to be taken into account when checking your sensor accuracies. A short run harness can use a thin film element with no issues, but if you have a long run, wire wounds are typically less sensitive to harness noise. There are ways to compensate for this, but that adds cost, which affects the component selection process. All in all, this covers the best points of both sensing technologies.
Nice Article, one other big benefit of RTD sensors over thermocouples is that you can use standard copper wire between the sensor and the controller. Thermocouples require compensated conductors all the way to the controller.
Platinum thin- film temperature sensors can be used in ovens where they have replaced electromechanical regulators. The sensors measure the temperature in the oven during the baking process. The electronic control systems allows to store different heating profiles, which the oven can use to react intelligently to the different types of food being baked. There is no longer a need to cook by trial and error method.
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.
