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.
