I have everything connected and running great. I am running the VoltageRatio example thru python in visual studio and it reads like it’s supposed to. From that obviously my output values are in voltage ratio. I’m not sure how to convert this to weight. I know the values above are needed but I have been unable to get to the correct solution so far. Any and all help is appreciated! New to load cells
@AudioVOX
I have already done all of this. I understand how to setup and run the phidget with the load cell and have it return information to my PC. That is not the issue, my issue is the only thing I can get to return is voltage ratio and I’m not 100% sure on how to convert that (unless I’m just completely missing something from the link you posted). There are a few things about this online but nothing that has gotten me from point A to B.
So from what I’ve gathered, you do the following:
(1) Take the individual load cell characteristics:
resistance: 700 ohms
excitation voltage: 9-12 VDC
sensitivity: 1.9997 mV/V (?)
max weight: 1000 kg
(2) Multiply load cell reading (mV) by full scale weight to get a number in volt-pounds
(3) Divide previous number by { sensitivity (mV/V) * excitation volatage (VDC) } - This results in pounds. Which is the final result I want.
My problem is in step 2 my output is in voltage ratio (mV/V) NOT voltage (mV) - I’ve tried using the VoltageInput and VoltageOutput code but they always fail. I can only get the VoltageRatio to work.
