Fuel pressure sensor

How fuel pressure sensor work.i mean internal construction

Hi Akash,

Can't imagine why some of the Forum experts don't answer - I feel it is impolite, not to respond to a question.

Sorry, not an electronics person so my response is speculation:

I assume, these days, a pressure sensitive (load?) cell. In past would have been a diaphragm or Bowden tube style devise.

One thing I have picked up, from other Forums, is that these devices are prone to erratic/erroneous reading, when in direct contact with the fuel.

The advice is to mount the sensor high, so that it is reading air/gas pressure rather than raw fuel AND so that the connecting tube has a chance to drain between engine starts.

I have found the above advice works for my installation.

So Rhino - it seems, from your reference, we are still using the Bouden tubes or similar - no solid state load cells as yet (assuming your reference is up to date).

Is there some good reason you could not have told Akash408 that there has been little progress, in aircraft pressure sensors, in the last 176 years or so, since the Bouden tube system was invented?

Sorry Skippy. I've placed you on ignore. You'll have to find someone else to poke sticks at.

Sorry Skippy. I've placed you on ignore. You'll have to find someone else to poke sticks at.

In my very short time on this Forum, I have found, with only one or two exceptions, the respondents to be, in general, curt.
Unfortunatly you are not one of the exceptions.
You may benefit from jumping of your high horse, standing back and & have a think about your demeanor.

he's ignoring you so he won't see it. i'm not sure why you jump on everyone's shit for the smallest thing skippy, i don't think you mean to but I can see how it might piss people off.

Be kind. Be humble. Admit your failings/errors and I won't bite - simple!

I find it interesting that you consider it "impolite" for others not to answer the question, regardless of whether or not they have a correct answer - but you have no trouble at all jumping up and down waving your hands and proclaiming that you don't know anything about the subject but are happy to speculate about it.

What does your therapist think of this?

“Tolerance from ignorant behavior”
From the guy that doesn’t understand how basic math works.

Around here it will help to let some of the negativity roll of your back from time to time.
