DIY Verus / Vantage Pro pressure transducer

Having watched a number of the ScannerDanner videos on Youtube where Paul gets out the Fluke PV350, I’ve grown increasingly envious of him being able to see cylinder pressures in real time and comparing them to spark plug firing times.

I’ve looked around at the prices for the Fluke (£200) or the Snap-On (couldn’t find it on their website, but I probably couldn’t afford it anyway).

Attached below is a .PDF with instructions, pictures and links to parts. If you can solder up three wires and buy a few bits from Ebay you can build this in ten minutes.

Well done paul nice set up and very cheep
Good PDF file keep sharing

Nice Paul! THNX for laying the groundwork. I'm looking to do this exact thing for my Pico scope. The only difference is iam going to see if I can set up the power as a USB cable and that way I'll get a nice 5v reference. I ordered a 300 psi and a 500psi transducer. I'll let you guys know how it goes when they come in!

Does this still work well for you? Using the serial port on top to power the transducer.
Found any problems at all? Thanks

Seems to be fine on both my Verus and Vantage Pro.

Cheers,

Paul

I just finished making mine from 450psi transducers we use on our ac systems on the busses. I decided to have mine powered off of the USB port. And I put a 500ma fuse inline on the 5v ref wire to protect the Verus. I just got done testing it by connecting it to the high side of the ac system and then monitoring pressure on the Verus. Seems to work great

Got any waveforms to share using the homemade transducer?
Does it work on vacuum or anything else? Or does it just work for in cylinder testing?

I can get some for you to see. I’ll post them tmrw morning
