Here you can find a fuel pressure sensor having a gauge and an alarm outlet pin:

See the calibration test result below.

The alarm sensor part switches on below 0,8 bar. (useful to lit "oil-pressure-too-low" indicator lamp)


Another type fuelpressure_sensor:

Its calibration curve is linear:

This is not absolute pressure, but relative to athmosperic. So 5bar measurement range means (1 bar athmosphere) + (for example):

//Is this a 5 bar operating range pressure sensor?

I have 3.5bar base fuel pressure and 2.5 bar boost...
