 This maybe a simplistic view but looking at the problem of determining the angle at which the sensor strikes the master seems to be as follows: Consider a Right Triangle with the base labeled AB, the hypotenuse labeled AC, and the following being defined: 1. Line AB is the difference between inside and outside radii of the Master. 2. Line AC is the difference in distances measured by the sensor between outside and inside edges of Master 3. The angle at A formed by Line AB and line AC is the sensor angle. A first approximation of the angle A is therefore the arcCos of AC/AB. A more accurate determination could be found if you consider the length of Line AC is adjusted by the curvature of the master. One final note: If you are only interested in determining if the radii of test devices placed in the measurement tool fall within some acceptable tolerance, you could avoid all the messy calculations simply by maintaining the master measurements and comparing acceptable results against new measurement values to determine if the new values are within an acceptable range. This may mean the masters are designed to define maximum and minimum acceptable radii.
