Inductive position sensor
max. 120 mm, IP67 | MKU 215 series
Proxitron GmbH
The inductive analog sensor is suitable for noncontacting
measuring of distance or position
referred to metals. The measuring principle is
based on the physical effect of change of quality of
a resonant circuit which is due to eddy current
losses in conductive material.
The high-frequency pulsating field of a LC
resonant circuit leaves at the active surface of the
sensor and is periodically excited by a pulse stage.
As soon as electrically conductive material enters
the field eddy currents result. Energy is taken from
the resonant circuit, and its amplitude and decay
time are influenced proportionally to the object
distance. A μ-processor serves for integration of
the energy of the resonant circuit and determines
the resulting output signal.
The electro-magnetic field is non-interacting, i. e. it
does not produce any heating in the object to be
measured nor does it have magnetic influence.
Acc. to function measuring is carried out referring to
moved or stationary metals. For fast processes it
has to be considered that the periodically excited
resonant circuit reaches a measuring rate between
100 and 250 per second.
The robust design in potted housing and easy
handling make possible industrial standard
solutions as well as sophisticated applications.
By means of two incorporated push-buttons
measuring range and individual curve shapes
can be programmed. Apart from the measuring
value output a serial interface is available.
