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!
