I am not worried about old sensors, since they go straight in the bin when diagnostics show problem with them. I will be using this "tool" only with brand new sensors, which I need to put in position 0.0° before mounting them.

Then all you need to do is measure the output of P3, set the sensor so it's half VP for position, for Torque make sure T1 and T2 are equal, you don't actually need to do any calculations to determine angle/torque.
You could do it with a dual comparator and some LEDs but it sounds a fun learning project for an Arduino.
Sampling rate for taking static measurements isn't that important as long as you've given the filter and ADC time to 'settle', ten measurements in 100mS isn't arduous

Thanks! Yeah, I think I will just use suggested passive components to create filter, but nothing else otherwise ... I will just connect it to standard Arduino Mega. 10-bit resolution should be more than enough, since correct torque resolution in this case is 0.0122 degrees. :)
