Sensor Applications
Sensing Solutions Summary
Hypodermic Needle
Quality Control
A remote source and
detector pair inspects for
passage of light through a
hypodermic needle. Their
small design and waterproof
stainless steel housing are
appropriate for crowded
machinery spaces and
frequent washdowns. High
signal strength allows quality
inspection with hole sizes
down to 0.007 in.
Motion Position Detection
A tubular E57 proximity
sensor is used to detect the
presence of set screws on a
shaft hub providing a control
device with signals for speed
regulation or detection of
rotation.
Web Flaw Detection
A web passes over an array
of retroreflectors. When light
is returned to the sensor
head, the output is energized
and the web shuts down.
Because of the superior
response time of the control
unit, high web speeds can be
maintained.
Motion Control
A pair of tubular proximity
sensors is used to determine
full open and fully closed
valve position.
Clear Plastic Web Break
Detection
The clear web is detected by
a wide beam diffuse
reflective sensor. The wide
beam helps it ignore
reflection caused by
fluttering of the web.
Web Guiding
The 1372A-6501 slot sensor
head is mounted so that the
edge of the web extends into
the slot and blocks half of the
source beam. As the web
moves into or out of position,
a proportional signal is
provided by the analog
control unit to alert your
control system.
Web Splice Detection
When the two thru-beam
detectors see the same
signal strength, the output is
zero. When the opacity of the
web changes, as in a splice,
the signal strengths are
thrown out of balance and the
output is energized. This
system can be used on webs
of different colors and
opacities with no system
reconfiguration.
