10bar VDO oul pressure sender and SYL-1813B

[brum]

I have a 10 bar VDO oil pressure sender (2 pins, resistive sensor, one to ground, one to gauge). According the info I found on the internet it should work in the range of 10-180ohm. However I'm not sure if the VDO resistance is linear to the pressure it read.

The SYL-1813B has setting for 0-375ohm pressure sensors. I suppose this is the one that I should use. What is the correct setting for the 10 bar VDO sender?

If I'm calculating the range linear it should be -0.59bar at 0ohm and 22.06bar at 375ohm. Is that the correct setting?

Well, it seems that the sender is linear. So this should be the correct range. With one little change - 375ohm = 21.47bar, not 22.06bar.

Yes, you are right.

It should be -0.59bar at 0ohm and 21.47bar at 375ohm.
