I've taken a year out of university to work at a design company and they have given me a project to design/make a test rig which measures the position of a metal shaft within an actuator assembly to check if its within a +/- 0.2mm tolerance. Some of the key requirements are:
I've been looking at inductive and photoelectric sensors from http://www.baumer.com/uk-en/ however I can't find a product which can accurately measure the position of the shaft down to 0.01mm
- No contact with the shaft
- The sensor is going to measure the end of the shaft to check if its within +/- 0.2mm tolerance. Therefore it would need to be able to read a change of less than 0.1mm.
- Output must be repeatable as it is going to be used to measure a handful of parts off the production line
- It needs to be easy to use/ display results clearly
- measured shaft has a diameter of 5mm
