Part III: The Equipment
Operating Principle*
The system uses a principle of impedance variation which is caused by
eddy currents induced in a conductive metal target. The coupling between
a coil in a sensor and a target is dependent upon their displacement (gap).
The electronics consists of an oscillator, linearization network, amplifiers,
and a demodulator, which provides an analog voltage directly proportional
to displacement.
