Sounds like the same school-homework-question as in your AVR-request.
Do you know the magic characzters P L E A S E ?

I now fully understand what the term "Elephant skin..." means.

It matters not what you tell this person, he just keeps on and on and on ...

Same arrogance, same laziness, same "you owe me"... style. Just ignore him.

just wonder if you really know the answer to his question. you talk like as if you are a expert yourself. In true, you do not know the answer either. if you don, then please keep ur mouth shut and start reading up to enlighten your shallow knowledge.

This sounds just like a question I had to answer on my our several years ago.

Are you in College?

How old are you?

This info can be obtained VERY EASILY by using an Internet search engine such as Google. Are you that lazy that you want to have us do it for you?

Quit relying on other people to start doing something with your life!!!

Inasmuch as utilizing Google has been offered as a suggestion, it might surprise us to find out that one of the chief Google responses is this very blog, within which we, for whatever reason, have shown such disdain to the question/questioner. Needless to say, it does not reflect well upon our community to have these responses show up in prime Google time. (Just type "Differential Pressure Transmitter Schematic" into Google to see the problem.)

In future, realize that your responses are now available, not just for pramanji to see, but for the whole world to note; and perhaps shape your languaging to suit.

Pramanji, I became interested in the number and variety of available types of comparative pressure sensors based upon your inquiry due to a project I was working on, in which I hadn't realized yet that comparative sensors would solve certain issues. Thank you for posting the question.

Since there are a great many uses and methods of comparing pressures ranging from two sources into a comparator to electronic signals across a bridge to several piezo crystals under varying pressures, etc. etc., you will have to be more definitive about which system meets your current needs. From my own investigation, none of the systems/schematics available is super difficult to understand/read; and most of them can be accessed via Google and several other free sources by entering the above key words into Google, which is a very useful internet search engine overall, and costs nothing to use. May I suggest along with my colleagues that it could be very useful for you as well.

Pramanji,

This is forum of Engineering professionals. from the tone of the query it looks like you are from a college. why dont refer text books.Or some Instrumentation handbooks.

I just wonder if you people really know the answer to his question. All of you talk like as if you are a expert yourself. In true, you people do not know the answer either. if you don, then please keep ur mouth shut and start reading up to enlighten you knowledge.

Hi, Guest!

There are a great many varieties of differential pressure sensors, believe me; and a great many varieties of transmitters adapted for recognizing/interpreting/transporting the signals received from each. All of the above have to be calibrated/adapted to specific situations; because there are thousands of situations --entirely different from one another-- in which pressure sensors perform as a necessary (required) component in different operations in different fields and applications, and in different stages of development. Every engineer is aware of this set of circumstances.

Hence, there is no ONE "answer" to the question. Only pramanji knows which one, at the point of his original question, he wanted to find out about.

The people on this website are mainly engineers...from a variety of engineering disciplines. All have completed courses of studies in the most advanced areas of their engineering fields available at the time they were in school, sweating blood, staying up all night, or to the wee hours of the night several days each week followed by classroom and lab attendance, in coursework and tough examinations that entailed thousands (NOT exaggerating!) of hours of learning and study and memorization of hundreds of formulae and methods of investigation over months and years of dedication and effort fueled by the desire to make a contribution in the most fascinating occupation there is. You bet your ass we're experts; and we deserve to be regarded as such, whether or not we "answer" a question straight out.

This website is of the unique variety that brings together engineers from a great many fields of engineering expertise under one umbrella-blog-sharing experience. When someone asks a legitimate question in here, the chances are that responses will come from not only engineers in the specific field related to the question, but from others who approach the question from their own particular field of engineering slant on the subject. It's invaluable and wonderful and a tribute to the powers of the internet to have such a website. (OK OK, and it's also a tribute to the guys who set it up .)

Pramanji got what he was asking for. He also got a finger-wagged at him for asking the question before he had done sufficient research on his own. Have another look at the responses before you wag your own finger at us.

Mark
