Hi
I have a strain gauge load cell that i got from a small electronic scale. I would like to view the volteg of the electric signal produced by the load cell (when an object is placed on it) on an oscilloscope. I have tried connecting the load cell sensor wires directly to the oscilloscope but i get a constant voltage signal. It does not change, even when i change the weight on the load cell. Please help!
 

Hi,
Do you have checked a data sheet pls?
What is your nominal output?
Here is some lecture as linked:

Usual is a load cell, as I know, to drive in a bridge and has very small outputs!
Are you sure, that what you see is not only a common mode signal or offset on output?
Load Cells & Load Cell Amplifiers:

Let read a data sheet pls...
