Hi

To Cory Spackman :

I have to go for 0.1mm resolution only. so we should use 16bit ADC with 14bit resolution as suggested by you. Thank you.

To Erik. :

plese tell me more details on that card where can i get it. I could not understand transmitting differences ? if you don't mind elaborate it.

To Peter :

My petentiometer is linear transducer either 5k or 10k. There is no rotary arm at all. its length is stroke length (1000mm) + ~ 50mm. So it is possible to move the wiper with 0.1mm resolution.

for info : CNC milling machines have resolution of 0.001mm with same type of transducers. but speed is less. (10mm/sec ). my project is also similar to that except more speed with less resolution.

thanks to all
