DCR-WEB
Ultrasonic Web Controller
■
Operational Description
The DCR-WEB is an ultrasonic
position control system designed
for the demands of web control
applications.
The DCR-WEB operates on
the principle of “time of flight”
measurement of an ultrasonic signal
generated by the transducer.
The 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).
The 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. The controller
specifically rejects difficult-to-filter
noises from broad spectrum sources
such as pneumatic valves and
cylinders. The controller program
is designed specifically to offer
programmable features desired by
engineers controlling web tension
and roll diameter in their industrial
processes.
