Question on Monitoring O2 Voltage...

[Bob Wooten]

IMO, it would work but I would like to see something with a little wider
input voltage range.  This only has a 200 Mv input voltage.  I am sure that
they probably also make one that has a 2000 mv input as well, & I think that
would be a better choice.  we have one @ work that is a 2000 mv input that I
have used for a number of projects, but even with the volume that we buy
them in they are still $65 each.  If anyone is interested I can post the
zero & span adjustment circuit that I will probably use for mine.  I need to
find a different op-amp for it as the one that I am using right now is a
+/-15 Vdc unit, but I have that power in my instruments @ work so it is
simple to pull power for them & this is what I have on the shelf @ work.

Hello all,
   Has anyone from the list checked out this item on the PartsExpress.com
website?  It's a digital panel meter, with selectable decimal point and 12V
operation.  The part number is #075-400, which you can type into the Quick
Search field on their website.  Do you think this meter could be wired in
series with an O2 sensor to monitor real-time voltage?  I do like the idea
of
a real voltage display, rather than an Intellitronix Rich/Lean Indicator.

      Thanks in advance,
