Hi,

For my project I am plotting a Force vs Displacement graph using 2 analog inputs which are going to a DAQ.

The two analog inputs are coming from;
-A 5k potentiometer (for the displacement)
-A 1000 lb load cell sensor (for the force)

I would like to use a regulated 12V DC (1Amp) power supply for both the potentiometer and the load cell. I would like my graph to be accurate.

I am curious as to if the output values from one device will be affected if another device is using the same power supply.

Do I have to worry about this potential issue if I am using a "regulated" power supply?

Here is a link to the power source I am using ;

Here is the datasheet for the load cell;

Thank you.

 

You should be ok with one psu, the one you posted is rated at 1amp, so as long as your current limit is under that, ok...
