I am a little confused on the wheel angle sensors being talked about here regarding potentiometer and a Hall sensor, mostly due to my lack of knowledge on them. Can the hall angle sensor 
talked about in the “Wheel angle sensor” thread be used in place of the WAS in parts list. . I really like the hall angle sensor and it looks to be easier to mount, but in reading this thread I am wondering if it will work??. Also I have seen some sensors with three wire and some with four wire connections will both work. The board does have connections for 4 but most are using just 3. Getting ready to power up my board but the WAS will be the hardest to mount so any help is appreciated.
Delphi seems solid and easy to mount.
It is difficult to get full reading (0.5 to 4.5) V mostly, of a 360 degree sensor, unless the sensor is programmable or you have a wheel on it.
Don’t buy a normal potentiometer type as they wear out faster than hall type.
Honeywell and others sell preprogrammed sensors (like the Delphi) with full reading on eg. 60 degrees 90 or 120 degrees.
Only 3 wires are needed to make a hall sensor work. 6 wires indicate it is redundant /have 2 sensors inside, 4 wires could be redundant as well.
On link hall sensor are to sensitive(I am test one), 0-360 output from ~0-5V , from 80-90 angle ~1,1V , and noise from ADC, avoid.
Do you actually mean not sensitive enough? But why use a 0-360 degree sensor instead of one with a range matching the individual installation?
I neither see the noise point. A properly installed hall sensor should not be any more noisy than a potentiometer.
I’m with Larsvest on the durability point too.
I respect your view but my vote would go for a hall sensor.
If you use ADC(analog to digital converter) you have noise (wire like antenna , DC motor and driver , switch solenoid(relay) GND loop…) , and if ADC range are 5V and you using just 1V, not good. If 90 degree 0-5V that is ok. Yes hall sensor are better but digital output , avoid conversion Hall(digital)>analog>ADC>digital.
Actually grabik vas pointing out the same issue as me, with the 0 to 360 degree sensor. Therefore the possible noise will have greater impact on output to AOG, when voltage output difference is only 1.1 V at eg 80-90 degree.
I see, I did not understand his message. But the 0 to 360 degree issue has nothing to do with hall sensor versus a potentiometer, both can have 0 to 90 degree full range. Just that the hall sensor typically runs from about 0.5 V to 4.5 V. I have a hall sensor with a 25 degree full range.
Yes pots and hall sensors are the same, regarding the full output combined with the working angle.
I don’t agree with grabik on the output from hall sensors, it is analog voltage somewhere between 0 and 5 V, although some have a built-in ADC converter that output numbers.
Can you recall what size fittings you used out of your hydraforce block @Kaupoi ? I have an SAE6 valveblock, thinking of using 3/8" flow control valve, and isolator valves?
SAE 6 is UNF 9/16" https://www.surpluscenter.com/images/techhelp/SAE.pdf
Something like this should work for you https://www.kiowa.co.uk/1219-P00006712/3/8-BSP-x-9/16-UNF-Male-Male-Hydraulic-Adaptor-c/w-O-Ring
Should I be using larger hose / fittings in that case? 1/2 inch? What size hose / fittings are you using @Kaupoi ?
Think the 57C is rated max 37L/min, all the fittings i was looking to use of 3/8" size are rated for over this, and planning to use a pressure compensated flow regulator on the P line anyway, so 3/8 should be more than big enough I am thinking?
57C is max 23L/min. I have 3/8 hoses except at LS there is 1/4. 3/8 is big enough.
Perfect, thats exactly what I was planning, so think I should be ok there!
I assembled and tested these hydraulic systems using cetop components, check valves, 6-way valve, alternative valves, for OC and LS, work very well.
Now I have ordered the production of a valve plate in which all valves will be integrated into one module. The total cost will be around $ 500 - 700 and it will be very easy to mount the subassembly in both OC and LS systems.
If they were willing I could provide a ready hydraulic assembly to anyone interested, but this is only in about 2 months.
What do you think about it

Hello. You didn’t think about using a priority valve.
