I think the frequency response is more a function of the packaging than anything esle, typically. Though I have seen the self resonant frequency listed for some high pressure high end sensors. And those would be in the kHz range.
Do most pressure sensors specify the frequency response range, or is this attribute only provided on certain class of pressure sensors? This is a value that may or not make it to the data sheet. Some suppliers can provide a value if you ask. For applications where a minimum value is required this could lead to competitors specifying the value on the data sheet.
Which unit of pressure is used for what type of pressure sensors and why ?
The pressure units are in most cases determined by the application and not the sensing technology. Different techniques can be and are used for liquid depth but the measurment in either inches or feet (meters) of water. For tire pressure: PSI in North America.
Question for Randy: REF slide 13, proof pressure. since proof pressure includes the pipes, tubes, or hoses; does an equivalent measurement or specification for shrinkage exist to address vacuum application?
Asolute is referenced to a vacuum, guage to a reference pressure, usually ambient and differental to the difference between the two ports. In atmpsphere the three gages would read, respectively 14.7, 0 and 0

If you experience audio interruptions and are using IE, try using FF or Chrome as your browser. Many people experience issues with IE. Also, make sure your flash player is updated with the current version. And finally, some companies block live audio streams, so if that is the case for your company, the class will be archived on this page immediately following the class and you can listen then. People don't experience any issues with the audio for the archived version.
Sensor1 - No, unfortunately there isn't. If your company is blocking the live audio stream, you will be able to listent o it on-demand immediately following the class. People don't experience any issues with the audio for the archived version.

You are eligible to earn IEEE Professional Development Hours by attending these courses and participating in the chat function. Additionally, we are no longer using the points system, offering "graduation", or giving grades. The IEEE hours are taking the place of that. There are some important things for you to know about earning the hours. The most important ones are that you need to attend these courses live, you need to attend a minimum of two of them per semester, you need to fill out a course evaluation form within 2 weeks of the end of the class, you need to attend 4 out of the 5 classes per course, and you need to participate in the chat function every day you attend. Please click on the link at the top of this page that says "How do I earn IEEE professional development hours" to read all of these important details and more.

The streaming audio player will appear at the top of this web page when the show starts at 2 PM Eastern time today. When you see it, click on the play button to start the audio. Note however, that some companies block live audio streams. If when the show starts, the audio bar doesn't appear or you don't hear any audio, try refreshing your browser. If that doesn't work, try using Firefox or Google Chrome as your browser. Some users experience audio interruptions with IE. Also, make sure your flash player is updated with the current version. If that doesn't work, the class will be archived immediately following our live taping. You shouldn't experience any problems with the audio when listening on-demand.
Some cars are more reliable than others, but even the vehicles at the bottom of this year’s Consumer Reports reliability survey are vastly better than those of 20 years ago in the key areas of powertrain and hardware, experts said this week.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
While many larger companies are still reluctant to rely on wireless networks to transmit important information in industrial settings, there is an increasing acceptance rate of the newer, more robust wireless options that are now available.
