Specific Example: 15N Sensors
The estimates below are for a 15N sensor. The estimates are based on the coil diameter of 143
mils (3.63mm). The two tables contain the same data, just in different units. Note there is an
entry for a 2 mil range (+/-1mil) (~50 micron -- +/-25micron). This entry is based on a
considerable amount of experience with this system and was not calculated.
