devicenet height sensors?

HEllo!

I am currently using a sensopart height sensor(laser) to tell me the height of product at various stations. Problem I am having is it seems like at high speed the numbers are not consistant. Looks like it is acting like a PID loop.

Was wondering if any of you have some info on a different kind of sensor i can use that will not jump around soo much.

Thanks

Banner has some good distancing sensers they have a teach ability so you can calibrate them

Check out Rockwell(AB) they have laser sensor with DeviceNet output
