thanks once again sir randy for giving this kind of lesson for day 3 class. now, another day 4 to go ahead for this course to finish the class for 1-week...
thanks to digikey and design news for giving this PDH Continuing Education for our improvement and development in adding additinal knowledge in mind for our engineering profession...
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 is the control technique in case when temperature does differentiate the accuracy of sensor readings in the pressure measurements?
You normally either need to monitor a parameter that changes reasonably linearly with temperature or have an additonal internal or external temperature sensor.
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.
That would make it make more sense as you noted the premise was based on a filter for a computer filter not a fillter in a pneumatic or hydraulic system.
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.

Most cases have internal signal conditioning as it has tighter tolerances, makes integration easier. Some specific cases external for more flexibility.
When searching for suppliers, I proceed with caution, looking at availability, lead times, etc. So, basically my search mirrors Randy's approach for any type of supplier part.
That's why I give my g/f my Starbucks gift cards, she doesn't do coffee either but likes something they offer. I don't bother, Starbucks doesn't sell Pepsi. :)
For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
