All good info guys. Those magnetic sensors are really appealing. I want to try those. Siko Global gave me a quote for some magnetic heads and 10" of tape and that setup is just under $700 for one sensor, tape and cable which is actually more than the Balluff sensors we were looking at. That Ebay link for the Renishaw like sensors is really tempting. Almost too good to be true. I found out that the Balluff price we got for the magnetostrictive sensors were for two sensors for just under $1200 including cables and sliding magnets so we are going to go with those. I was originally told that they were $1200 for one sensor setup, which I had a problem with. The job is tight on time as they want the machine running by 3/15 and Balluff assembles their sensors in Kentucky which is close so we are heading in that direction. I've use Balluff sensors P profile sensors before and they hold up really well. Unless they are mangled, they typically never die.
