How to compare two sensors with one 0-5v vs 5v-0
Currently have a hydraulic height control thst uses 2 sensors. One on each end of a 20' header. The left sensor is 0-5v and the right sensor is reversed at 5v-0.
The left sensor controls a cylinder that tilts the header left/right.
The right sensor controls seperate cylinder that raises complete header up/down.
Wanting to change from on/off solenoids to proportional ones. Each valve has seperate coils for each movement....
Not sure how to make a variable scale with sensors going in opposite direction.
