PRINCIPLE OF OPERATION
The
T-NC
system
generates
a
radio
frequency
field
which
is
radiated
by
the
sensor
surface.
When
the
reference
surface
facing
the
sensor
is
invested
by
such
RF
field,
an
eddy
current is generated on it. The energy required to generate such eddy current (which is
proportional
to
the
distance
between
the
reference
surface
and
the
sensor
surface)
reduces, in proportion, the energy present in sensor. Such difference is then detected
by the converter.
The converter amplifies and processes this signal thus supplying a d.c. output voltage
proportional to the distance under consideration.
