Hi guys! I am a newbie in electronics, still a student, and I am in the stage of developing a load cell, it has to have as inputs the pressure sensor, sensor enable and as outputs a set point, pressure value, amplified pressure value [0.10v ] and output. How to set a potentiometer in the set point and one to perform the offset! This is what I have for now! Opinions, I know it's not right, I'm having several difficulties

 

hi Fabio,
Welcome to AAC.
What type are the OPA's.?
What is the load cell mV output range.
E

 

The OPA's is a LM324n
Load cell output range is 2,1 mV

 

OK,
So its 2.1mV/Kg, what will be the maximum mV.? [Kg]
What are the difficulties with your circuit.?
E

 

hi,
This is what I see with LTSpice.
What are the potentiometer values.?
E
