So I’ve got myself a little in over my head on this project…
I’m utilizing a load cell and linear actuator to make my tensile stage for mechanical testing materials. I’d like to use an Arduino Uno but don’t know if it is capable of what I need.
I’d like the loadcell to be used as an input to a created GUI where I can I put a value, where it will then output to the actuator to hold constant loads etc…
I’ve attached the equipment below (minus arduino uno) as well as a wiring diagram from the actuator.
IS that why the picture is upside down? What is a tensile stage? If you don't know if a Uno is capable, how would we know? That is why you test things!
If you have a motor and an inline tensile load cell stage what is the need for the accuglass 2" Linear Travel Feedthrough? It looks like that device is a mechanical readout of displacement.
If you use a stepper motor or a dc motor with an encoder readout you should be able to know the displacement for the load cell reading.
As @groundFungus says, The 4 wire load cell signal will need an amplification circuit. An HX711 is commonly used.
An Arduino Uno should be able to drive a stepper and read a load cell.
So, you need a variable pulling force. What will be the maximum sustained force (in Newtons) for what period of time? If there is movement (displacement) involved, what will the maximum distance be (in mm)?
Can you tell us why you have chosen this motor instead of a stepper?
The entire configuration of the load cell, readout, and motor does not seem chosen for computer control. What is the motivation for these design choices? Can you explain more about what you are testing and the how you plan to to test?
