100 psi pressure/vacuum sensor

[beamerdr]

I have a EEPV302AL pressure /vacuum sensor http://diagnostics.snapon.com/display/1252.nws That I would like to check compression wave forms with. As per the Bernie Thompson article http://www.automotivetestsolutions.c...ersarticle.htm
I don?t need the exact pressures, just a accurate representation of the wave form. My question is has any body tried this with this sensor? And will it be damaged by over pressure that may accrue?
Thanks Scott

It can work for this test but the 500psi transcducer is a safer bet. keep in mind most vehicles test well over 100psi on a traditional compression gauge

Here is an example that Carl B shared with us on another thread. (http://askatech.autorepairdata.com/f...read.php?t=184) I'm am sure some of the members will share more with you.

Of the three psi transducers, I use 100 psi for vac. and fuel psi tests, I use the 500 psi for compression.

Hi Kevin,
Can the 500 psi transducer read negative pressure as would be needed to capture a running compression test waveform to check valve timing. I asked Jim Washebeck and he told me that he didn't think it could, he was going to check and get back to me but so far hasn't. I have used my 100 psi transducer and so far I have not damage it as running compression is low enough and I make sure to keep the throttle closed, however those first few pumps before it starts and intake vacuum builds are well in excess of it’s 100 psi rating.

By the way we are in the middle of a blizzard, it's snowing sideways & is going to get down to about -12 deg. tonight so just be glad we don't have you up here doing a class right now. Of course we could always get you out on the snowmobile trails and show you how to have in the snow

I think you might have better service from the fluke PV350 transducer it reads pressure to 350 psi and vacuum below 20 inHG. I hope I don't get kicked of here

In the description it says the pressure transducers also measure vacuum but does not give a specification as to how much.....http://buy1.snapon.com/products/diag...t_xdcr_500.asp

Maybe a call to tech support or someone here may be able to answer that for us....

I have the pressure transducers, all 3 of them, but have yet to use any of them in the 4 or so years I have had my MODIS. Seems simpler to use a vacuum gauge, fuel pressure gauge, but might actually try them out someday.

Does the EEP302AL read in voltage or someting else.I'm trying to use it to test fuel pressure with my old Vantage MT2400 and I don't even know what screen I need to use.

Can you hook it to regulated air pressure you can see what the air pressure reads at gauge and start at zero and work your way up to 100 psi and select a volt scale on the vantage and note the voltage readings with pressure incrementally increased by 10psi and note the voltage and do the math I guess.
