how to mak an electronics scales
Thanks, Jourval!
Yes, I have measured them, they have about 10 kiloOhms.
This circuit becomes more complicated than I realised.
As I understand R2 and R7 are in the same orientation, so they are making reference voltage (without dependency of temperature).
R1 and R8 are located on the same way, so they are making reference point for second bridge.
So, measuring branche in the first bridge is R3/R4 , and in the second R5/R6.
I do not know, what diagonal pair R3/R4 is making here? Is it for some torsion measuring?
