Non-contact linear sensors have an
analog output that is proportional to
the damping target distance. Their
compact yet sturdy design makes
them suitable for industrial, robotics,
and laboratory use.
These sensors use inductive
technology, which means they can
sense any metal target. The sensing
distance, however, is influenced
by the metal target. Ranges are
calibrated using a standard square
target. The target is mild steel
(Fe 360), 1 mm (0.04") thick.
The side lengths are the larger of
either the sensor’s face diaphragm
or 3 times the sensing distance.
LD701-5/10, $290.
Sensing distances are influenced by
metals other than mild steel. The
“Correction Factors” chart, shown
below, shows the reduction that
occurs when brass or other target
metals are used. For example, if the
target were brass, the LD701-1/2
would sense 0.5 to 1 mm
(0.02 to 0.04").
The voltage output generated is
directly linear to the distance being
measured. The output can be read
by panel meters, recorders, computer
boards, or data loggers, all of which
are available from OMEGA®.
