Hi Bill Bradburry -
It's a long story... several years ago, I identified an MSP 340 transducer as a replacement for
fuel pressure (injected engines only), tried it and it functioned
perfectly. I posted it on the LML, others followed my recommendation,
purchased and installed them - all with excellent results. It
was a 100 psi unit, with a 100 mV full-scale output, but worked for
fuel pressure because it's utilized in the lower 50% of it's
range, producing the required 50 mV at 50 psi (the same could have been
done for oil pressure, but that would have required a 200 psi unit, which isn't
produced).
MSP now offers the
US300 series, one version of which is an exact replacement for the
MediaMate; however, it's combination of
5 VDC excitation and 50 mV full-scale is, apparently, rarely used in industry
and none were available anywhere. I contaced MSP and was told they could be
produced, with a minimum quantity of 5. So, I ordered 5 @ 50 psi (fuel
pressure) and 5 @ 100 psi (oil pressure). I've installed one of each
on my recently overhauled engine (not run yet) and sold the rest to others,
telling them not to send payment until they are verified to function as
advertised. Whewwwww....

Bill,
Is this sensor
actually working in your VMS1000 or are you saying that it should
theoretically work? If it is actually working it seems to me that these
less expensive sensors would be the sensors of choice for replacement until
such time as the entire VMS1000 system craps out. Or I guess that is
what you are saying??
Another
Bill
