KE-jet Pressure Sensor #006 542 50 17


I pulled this little part off of the 190E I'm parting. I didn't know what it was, so I ran the part number. It's described as both a "pressure sensor" and an "altitude adjustment sensor."

I'm assuming there's some sort of afr adjustment done by this part, from referencing atmospheric pressure from the nipple? Does anyone know how this part actually works? Anyone know how much pressure it will measure and what voltage range it operates in?

I ask because, if what I've assumed about the part is true, it could be used for fuel enrichment in a turbo application (with a boost reference line on the nipple). Just a little idea I had during the boring parts of the day.

Here's a picture of the part itself:
