Overview

Consistently detects changes in the edge position of transparent/thin/reflective webs - over a wide field of view. 
Not only is the Ultrasonic Autowide Sensor UHW resistant to changes in ambient temperature and humidity, this sensor for the detection of meandering web edges has outstanding features, including a function that automatically corrects the level of ultrasonic transmission when the thickness of the detected web changes. The Ultrasonic Autowide Sensor UHW is a meandering web edge detector that saves time and labor, and is easy to use.
  • Even if the detected material changes, the automatic thickness compensation function enables optimal detection
  • In addition to analog detection output, the UHW500 and UHW700 use CircLink, a digital communications network that is unaffected by the width of the detection field of view.
  • An automatic correction function which minimizes the influence of changes in ambient temperature and humidity
  • Can detect the edges of thin transparent films (3 μm or greater) over a wide field of view
