1. I have a huge metal block which rotates clockwise as well as anticlockwise. The speed of movement is not so high. However there is a huge shock which passes through the block sometimes.
2. I need to measure the amount of angular movement in degrees of the metal block be it clockwise or anticlockwise.
3. The accuracy I require is very high i.e. of the order of less than 5 minutes(1 degree/12). Also a high precision level is required.
4. The cost limit onto me is Rs 50,000/- or less than $800 dollars.
Any help will be appreciated. Thanks.
