Operational Description

e DCR-WEB is an ultrasonic
position control system designed
for the demands of web control
applications.

e DCR-WEB operates on
the principle of “time of flight”
measurement of an ultrasonic signal
generated by the transducer.

e DCR-WEB transducer can
be either an electrostatic sensor for
clean environments or a ceramic
piezo sensor for harsh industrial
environments. A variety of
transducer mounting configurations
are available (see dimensional
drawings and ordering information
for details).

e DCR-WEB controller utilizes
microprocessor intelligence to
allow filtering of the return signal
to discriminate the desired target
from unwanted false echoes and
ambient noise. e controller
specifically rejects difficult-to-filter
noises from broad spectrum sources
such as pneumatic valves and
cylinders. e controller program
is designed specifically to offer
programmable features desired by
engineers controlling web tension
and roll diameter in their industrial
processes.

Applications

®

DCR-WEB Ultrasonic Web Controller

e DCR-WEB is designed to
provide a direct interface and
control signal to many types of
drives used to control tension and
speed on industrial web processes.
e web material can be metal,
plastic, paper, rubber, glass, or any
other extruded or formed rolling
stock. e sensor is not sensitive to
changes in color, reflectiveness or
web temperature, as are other sensor
technologies. Ultrasonic sensors
require no contact with the rolling
stock and cannot damage or degrade
the product.
