Any mechanical friction eventually causes surface wear and consequent wear of the whole system. This is well illustrated by the cases of the motor brushes, motor-operated switches, rotary potentiometer, etc. On the other hand, as mechanical systems are typically large in size, it is difficult, if not impossible, to deploy them under actual operating conditions.
The magnettrack system is based on the noncontact magnetostrictive technology. The noncontact mode has numerous advantages, such as reliable performance, durability, resistance to vibration and others.
However, using the noncontact mode is not enough for severe commercial operation. Equipment is left to operate in dusty conditions, in environments with the solid particles in the air and abundance of dirt and soot far too often. Consequently, if the actual operating conditions differ from the laboratory ones, the optical measuring systems can malfunction.
