Linear distance sensor required with 1mm or less accuracy

I have a project. I want to measure the linear movement, in realtime, of a beam with a distance of around 10 inches. So i want some sensor which can detect this one accurately and can be attached to a PLC through analog input so i don't need other controllers or circuits for financial constraints. I know this is very much possible but I don't know what to use? I need some advice.

Re: Linear distance sensor required with 1mm or less accuracy

you can use a linear potentiometer for your project. if you search google there is so much variety there including distance to be sensed and resistance range. and what is good is that you can make a voltage dividr circuit to generate corresponding voltage to the linear movement and directly input it to plc. you can vary the resistors to meet your desired need.

if you think this is good.
