Hello. I am trying to come up with a miniature strain gauge conditioner/load cell amplifier for use with a full bridge sensor/load cell that has around 2mV/V sensitivity and 1100ohms and having a flexible 5V/10V excitation and a flexible supply anywhere in the range of 3-50Vdc.
There are a few similar solutions to what I want but no schematics/circuit diagrams available anywhere.

I just want the 0-10Vdc output..so it does not necessarily need 4-20mA, -+10V or 0-5V output if that makes things a little simpler.
I would appreciate if anyone is able to reverse engineer some kind of a circuit diagram that I can work with just so I have somewhere to start? Recommendations of the types of components would be very much appreciated too.
Please I hope you do not see this as me trying to get someone to do my work, I have really tried to do this myself but I am a beginner & I have struggled for a long while.
some of the solutions I have found are like the ones below which use a chip & therefore not fully analogue but they seem to make things more complicated than the solution above, I am looking for a solution that does not require programming or use of an arduino or any other mcu?:
