Ah! This looks promising! Reasonably priced, too. :) Thanks!

"628-08-GH-P1-E4-S7"
"Industrial pressure transmitter"
"1.0% FS, 30 psig, general purpose, 1/4" male NPT"
" .5-4.5 VDC output.  $89.50"

I didn't see clear pics of the connections... looks like pigtail leads. I would "assume" that 2-wire + shield audio cable could be used to connect this to equipment? (Power, Gnd, Output)

Willie...

I've installed a few and they seem to work fine. I think they are $109. Use the configurator tool to order the GH housing 0-5V output, 0-15PSIG, 1/8" NPT, and you end up with something you can thread into a brass tee and nipples to put the sensor right at the Heliax pressure port along with the air line.
