Solved! Re: MEAS oil & fuel pressure sensor driving me nuts

OK,
I just received my 150 psi transducers.
Wiring the three red, green and black, and done! I have perfect signal that I bench tested both for fuel press and oil press.
All system OK.
Start up very soon.

Re: MEAS oil & fuel pressure sensor driving me nuts

Thanks Marco!
I ended up ordering two new sensors that should arrive soon.
It also seems that I burnt one of them in my trial and error....
They are sensistive, I found out.
Appreciate your input though!

Re: MEAS oil & fuel pressure sensor driving me nuts

Did a Quick and Dirty yesterday, no go.
Managed to get a 5V signal and gauge that showed 7 bar pressure. But only static.
Yes, I will stop fooling around now.
Order coming. 50 UK Pounds plus shipping must be better than having a half good solution.

I really hope I am not making myself even more stupid.....
Like this on the 12 volt example?

Re: MEAS oil & fuel pressure sensor driving me nuts

Oil pressure without starting.... of course I have that! :-) The alternative I always use on new engines is a an external oilpump from a aircooled VW which I have modified to prime with a handdrill. Now for this type of testing, I just have removed the spark plugs, pressure comes after few revs on t...

Re: MEAS oil & fuel pressure sensor driving me nuts

DTA reads my gauges without running. No issue. I have found the problem, now I just have to figure out if I can wire this transducer for 0-5V. On one technical sheet I found late yesterday, it looks possibly there is a solution. The sensor is option #5. http://i859.photobucket.com/albums/ab151/losma...

Re: MEAS oil & fuel pressure sensor driving me nuts

Yes a 100psi. If I just get a 0-5V signal, I will scale it. Fourth green cable just means it is used when the transducer is used for option #1 & #2. Could it be that in fact both my units are wrongly tagged unit... you never know. Soon I will give up and buy at least the fuel unit from you guys ...

Re: MEAS oil & fuel pressure sensor driving me nuts

Thanks for very quick feedback. I have tried both my sensors and they give same result. Yes, I have tried both the VDO and the 10 bar DTA scaling. I have a couple of potentiometers and maybe someting in that range, (also a bunch of fixed resistors of 270 ohm that I could set in series) could try tha...
