Fuel Pressure Sensor for LM-1 Data logger

Grant Eldridge · 07-11-2011, 11:08 PM

Looking for a sensor to hook up fuel pressure monitoring to my Innovate LM-1 data logger. I've been able to monitor oil pressure with a small 1/8" pipe threaded sensor that is 0-100lbs and is powered by a 5 volt supply I've built into the car, but this sensor is not sensitive enough in the 0-10 lb. range to get adequate readings for fuel pressure. Has anyone had any luck finding a source for a sensor at reasonable (low) cost that will work? There is a Racepack one available, but at $250. way over my limited budget. I lucked out with surplus sensors someone was selling online for the oil pressure, does anyone have an idea for something similar for the fuel pressure? The oil pressure one I have plugs in with a NAPA available map sensor plug, quite small in size and looks/works well. Any thoughts? Suggestions appreciated!
This thing needs to output a signal of 0 at lowest pressure to no more than 5 volts at maximum pressure, with a 5 volt power input and a ground. Probably could work ok with a bit higher range like 0-20 as long as I can map out a voltage chart per pound of pressure increase for the software to interpret in that 0-5 volt range. Thanks!

I used autometer 1/8" electric sender and fed it 5 volts and used mechanical gauge to set the parameters.

I have a great supply of 0-5 volt sensors that work on any data system. In fact, Innovate and some others buy sensors from me for their kits.

a 0-25 PSI sensor is $130

Would this work? 30-2131-15g (aem performance electronics about $60). Specs are on the web site. Ron.

Grant,

We offer a 0-15 psi sensor, part number 2245, which is .5 volts at 0 and 4.5 volts at 15 psi. This can be purchased through anyone that sells Auto Meter.

Thanks for all the help! Looks like the AEM unit is the most cost effective and comes with a voltage/psi spec chart to enter into the software, as well as the connector pigtail all for around $60. There's even an AEM dealer near here, so should solve my problem, or they sell direct online. Much appreciated, all who replied!

Make sure you order the 30-2131-15g and not the 30-2131-15 (absolute pressure) . Let me know if this works for you as I will be doing the same thing in a week or so. Ron.
