Stereoscopic Width Gauge Width - Center - CropView - Thermal Profile Designed for extremely harsh environment Built in Ethernet with OPC UA & Modbus TCP Optional Industrial Network Protocol Easy installation and maintenance

Introduction The Stereoscopic Width Gauge DigiScan XD4100, designed for installation above the roll tables in hot strip and plate mills, is state-of-the-art technology for measuring the width and centerline of strips or plates. The stereoscopic arrangement permits high on-line accuracy despite material hop, tilt, lateral movement, and thickness variation. For use at the roughing mill or finishing mill exit, the self-emitted optical radiation of the hot strip provides sufficient contrast for width determination. An optional front light or back light mode is available for installation where...

Operating principle DELTA Stereoscopic Width Gauge employs an advanced digital edge detection process that captures the digitized camera data. Software routines running on the high-speed embedded processor perform sub-pixel edge determination in twodimensional space. The camera data are filtered using a high-speed Infinite Impulse Response (IIR) digital filter. Sub-pixel edge locations are then determined based on the second derivative of the pixel data. With two sub-pixel edges from each camera, the true width of the material is calculated using geometric triangulation. These trigonometric...

Connectivity The DigiScan XD4100 with built in Ethernet connection, integrated digital inputs / outputs and analogue outputs has a very flexible communication architecture and can easily be connected into any automation system. - Integrated Modbus TCP protocol, - Integrated OPC UA protocol, - Optional Profinet and Profibus-DP protocol. Thermal profile option Operator pulpit Host computer Ethernet Control room, diagnostic External I/O (optional) Junction box Ethernet switch Digital & Analogue I/O connections DigiScan XD4100: • Web server • Modbus TCP server • OPC UA server • Wifi access...

Temperature profile option The display of temperature distribution across the strip helps for a better control of the rolling process by isolating the source of camber, hook, or skid marks from reheating furnace… The temperature across the width of the product is obtained by calibrating the grey level output of the cameras to a temperature scale. The DigiScan XD4100 can provide: - Thermal profile versus time, in 2D temperature map - Temperature of up to 7 adjustable points across the width of the product. Specifications: 128 points per line, line period 25 ms, accuracy +/- 0.5% of reading...

Calibration Two-dimensional calibration is performed prior to delivery by placing a calibration fixture at several positions. Calibration is accomplished by collecting camera pixel data and then the stereo optical parameters are estimated. The width gauge is delivered calibrated in our factory. The installation’s position is not critical as the stereoscopic cameras will compensate for any variation in the distance between the strip and the gauge. Verification of accuracy and standardization The DigiScan XD4100 is supplied with an active verification fixture, including a certified mask with...
