Hi:
My car came with this pressure sensor (picture attached) and I'd like to use it in parallel with a mechanical gauge for oil pressure measurements. I think this sensor was part of an AIM data acquisition system, though on my engine it originally came as a plug for a cracked block .
Brand is "Measurement Specialities Inc", range is 100psi. There is no model or part number stamped on the id plate.
I went to the manufacturer website. I could not locate exactly what model this is. It seems that regardless of the model, they have different options available. Some can be powered through a variable source (8 to +30V), some have an onboard regulator.
Since it is fitted with an AIM style (Binder) connector, I think I got the pinout right from an online Mychron doc. I plugged the sensor to 5V (I am assuming this is what VRef is on an AIM system) and it seems to respond to small pressure variations (i.e. I blew in it).
Does this confirm this is a 5V powered sensor?
And what is the output scale, psi/V?
Thanks,
JS
