yes Ante, something did go wrong it was U2, I replaced it with another and it worked, and I tried removing the diode again and it worked find like you said it would ;D. Removing the diode didn't make any difference, except for having one less component which is good. The output from U1 is 2.43v to 3.62v. I tried using an electromagnet from a relay, and its influence on the Hall affects sensor was a little better than half that of the influence of the magnet. That's not all that good, the electromagnet that I used is about twice the size of what I wanted to use. So I may have to try to use a standard magnet. I wanted to use an electromagnet so I could very it's, strength giving me more opportunity for collaboration 
.
ante, just to be sure, yes I was pulling your leg, in regards to it being your fault something went wrong ;D. When you suggested to remove the diode, and I found problems after I done this, I hope you don't think I was pointing the finger at you because something went wrong ???, I would never do that, even if you did make a mistake on a suggestion and everything went up in smoke. I was just trying to use some good old Aussie humour, I hope you took it the right way, mate ;D ;D.

I was just trying to use some good old Aussie humour, I hope you took it the right way, mate ;D ;D.Ante, can you give me any suggestions, on how I can reduce the output to 0v, so than the sensor will start responding from 0v to the maximum that I want.
Yes wielding that soldering iron, after a couple of beers probably isn't a good idea ;D.

Dazza,
We need to know the output range from the sensor where it is supposed to work (0 to 25psi) or something like that. You have indicated 2.43 to 3.62V, was this the final decision or are there still changes to be done regarding magnets and moving ranges and so on. Until we

Ante, you mentioned in a previous post, that you didn't know what the output from U1 was, that's what those voltage measurements were from, the Hall sensor. Ok good, we know this circuit will serve its purpose with a little tweaking, once we know how it needs to interact with the other circuits. Thanks ante. Slowly but surely we are moving forward .
.Ante, aiming for good quality, workmanship and accuracy is important, even if it is a DIY job, I like to take my time and do as good a job as I can, quality not quantity . I am hoping for reliability more than accuracy for the pressure transmitter, 10% accuracy would be reasonable to hope for I think. I have a couple of washing machine pressure switches, for backup in case of over pressure or under pressure. Once I get to the stage of applying this system to a test vehicle, the pressure senses will have to be replaced, with ones that are designed to do the job reliably and accurately.
At the moment I'm working on putting together as much test equipment as I can, I'm building up the armoury ;D.

That's a good idea!!!
I know this is for a different section of this forum, but maybe
high-rated (and motivated Jr.) members will be able to put an "~~Aproved~~" stamp on messages and projects.
Just a seggestion.
