Sensor Applications
Sensing Solutions Summary
Lid Detection
A pair of tubular proximity
sensors used to, a) detect the
presence of a can on a
conveying line, and b) check
for presence of a lid.
Tollbooth Control
Thru-beam source/detector or
the long range Perfect Prox
diffuse sensor controls are
used to time the toll gate. To
eliminate toll cheating, the
gate lowers the instant the
rear of the paid car passes
the control. The E67 Long
Range Perfect Prox allows
you to mount the sensor on
one side, instead of both.
Plus with Perfect Prox, the
E67 will detect cars with
different colors and finishes
while ignoring all other
background objects. The
rugged control handles harsh
weather, abuse and 24-hour
operation.
Garage Door Control
A safe and secure garage is
achieved through the use of
thru-beam controls interfaced
to the door controller. The
door shuts automatically
after a car leaves, and if the
beam is broken while the
door is lowering, the motor
reverses direction and raises
the door again.
Cut-Off Saw Control
Note: All products listed are
required for each two-foot
increment.
An array of thru-beam
controls detect the length of
the log in standard two-foot
increments. The correct saw
is then activated to cut the
log at its longest standard
length. High optical
performance is a must in this
dusty and dirty environment.
Liquid Level Detection
A pair of E53 capacitive
proximity sensors are used to
sense high and low liquid
levels in a tank through a
sight glass. This arrangement
starts a pump to fill the tank
when the lower sensor is
energized and shuts the
pump off when the top
sensor is energized.
Web Loop Control
A sensor that generates a
“curtain-of-light” detects the
length of a loop on a web
drive system by measuring
the amount of light returned
from an array of retro-
reflectors. With this
information, the analog
control unit instructs a motor
controller to speed up or slow
down the web drive.
Bulk Material Detection
A capacitive proximity is used
to control fill level of solids
such as plastic pellets in a
hopper or bin.
Parts Presence
A limit switch style proximity
sensor, a Comet Perfect Prox
or the iProx Sensor may be
used to detect the presence
of a part in a pick-and-place
application for inspection.
The Comet will detect any
target material, color or finish
while rejecting the
background. The iProx can be
programmed to sense a
specific metal target while
rejecting all other metal.
