Need to know the part I am looking for Answered

I am planning another project.
It will be a somewhat Portable Steam Punk Balance ( Scale ) .
The idea is only one arm is to be exposed the other will be shorter and I want to attach it to ( PART? - I was going to say actuator but probably not the right part ) I want something that measures the distance it moves so it can be scaled to what the weight is. I want to hook this up to an Arduino to to the scaling and then output it to a display. The part will be hidden so looks are not important , I just want to know what is the name of that part and any sources would be greatly appreciated.

TIA for those that help.
