Ultrasonic web edge sensor bks+3/FIU/A

The bks+ edge sensor facilitates the contact-free web edge scanning of foils, paper and other soundimpermeable materials. Highlights 2 housing designs with 30 and 60 mm fork width IO-Link interface for support of the new industry standard Smart Sensor Profile more transparency between IO-Link Devices 0.01 mm to 0.02 mm resolution Very compact housing dimensions UL Listed to Canadian and US safety standards Basics Contact-free detection of the path edge for regulation of the web path 3 LEDs and 1 button on the top of the housing Parameterisable with LinkControl Robust metal housing Description The bks+ ultrasonic web edge sensor is a fork sensor for scanning the edges of sound-impermeable materials such as foil or paper. This is why the bks+ is ideally suited for the web control of high-transparency foils, light-sensitive materials, materials with greatly varying transparency and paper subject to high paper dust loads. The functional principle Both transducer and receiver are placed in a single, slim fork housing. The transducer in the lower leg is emits short, cyclical sound pulses. These are detected by the ultrasonic receiver in the upper leg of the fork. A material embedded in the fork covers the sound gap and thereby dampens the receiving signal in depending on the coverage. This is analysed by internal electronics. An analogue signal is output depending of coverage, resp. data word via IO-Link. Using the Teach-in button on the upper side of the edge sensor sets the zero point for the local edge. This calibration can be done in two ways: clear the fork completey of any web material, push the button for approx. 3 seconds
