Even if the detected material changes, the automaticthickness compensation function enables optimal detection? In addition to analog detection output, the UHW500 andUHW700 use CircLink, a digital communications network thatis unaffected by the width of the detection field of view.Ultrasonic Autowide Sensor UHW seriesConsistently detects changes in the edge position oftransparent/thin/reflective webs - over a wide field ofview.Not only is the Ultrasonic Autowide Sensor UHW resistantto changes in ambient temperature and humidity, thissensor for the detection of meandering web edgeshas outstanding features, including a function thatautomatically corrects the level of ultrasonic transmissionwhen the thickness of the detected web changes. TheUltrasonic Autowide Sensor UHW is a meandering webedge detector that saves time and labor, and is easy to use.Models UHW051 UHW280 UHW500 UHW700Power supply DC 15 V (12 to 18 V)Power consumption 1.5 W 2.0 W 3.0 W 3.8 WDetection field of view 56 mm 280 mm 504 mm 728 mmResolution Detects a web displacement of 0.1 mmDetection output 0 to 5 V or 4 to 20 mA 0 to 5 V or 4 to 20 mADigital communications network CircLink (SMSC)Linearity Within ± 0.2 mmUltrasonic emission frequency 223 kHzFrequency response 50 HzThickness and types of detectable webs Plastic film, paper, metal, etc. that has a thickness of 3 μm or greater (can not detect non-woven fabric)Ambient temperature during operation 0 to +50°CAmbient humidity during operation 35 to 85% RH (no condensation)Mass (2-meter cable from the main unit: 0.5 kg) 1.7 kg 3.5 kg 6 kg 7 kgUHW280UHW051UHW500 / UHW700System componentsThe CMOS linear sensor (model SLH30) is a sensorused in our EPC (Edge Position Control) system. It usesprojected LED light and a CMOS line sensor to detect theedge position of the web (the product in sheet form).The SLH30 is an EPC sensor that has been developed tobe able to detect a wider range of materials.Webs that are difficult to detect (such as tire cord,netting, non-woven fabric, electrical wires) can bedetected.In addition, the 4096-pixel CMOS line sensor gives anexcellent linearity and responsiveness.? An automatic correction function which minimizes theinfluence of changes in ambient temperature and humidity? Can detect the edges of thin transparent films (3 μm orgreater) over a wide field of view
