Fuel Pressure sender calibration

[SammyQ2]

I am installing an electronic fuel injection system in my O-200 and use automotive pumps.
Yesterday, I fired up the fuel system for the first time (yea!) just for a test, before I hang the engine.

I got hold of a pressure gauge and Tee'd it with the Dynon Sender.  I took resistance measurements, as I adjusted the pressure regulator, and wanted to see if the numbers jive.
My normal operating pressure will be around 45 psi
I plotted it out and it is linear.

Here is a sample:
Gauge (psi)  Resistance (ohms)
0       8.7
5       16.0
20      64.8
30      82.9
40     105.7
45     119.0
50     131.7
60     150.9
70     171.2
80     188.4

Do these numbers look correct?

I'm not 100% sure what you are asking, but those numbers match our 80 PSI oil pressure sender.

They look great.

Great!  I just wanted verification that the numbers were right. I assume the oil pressure sender and this fuel pressure sender are one and the same.

They're actually different sensors. The injected fuel pres. sensor maxes out at 80psi, while the oil pressure goes to 150.
