The family of Web Inspection Systems have served the paper industry for over 30 years. The history of ABB's Web Inspection Systems is in reality the history of all web inspection systems.
HDI800 - New platform with High resolution imaging (2007- )
The HDI800 is packed with a range of state-of-the-art technology.The more flexible SW architecture provides various benefit and makes it feasible to realize better customer specific needs. The advantages of ABB's earlier imaging systems have remained same such as the high resolution imaging from the smart 50 MHz sensor.
HDI8 - Smart 50 Mhz sensors (2005 - 2007)
Single board 50 MHz sensor technology with the smartest, high capacity detection algorithms and the highest resolution image processing available. The new sensor family delivers astounding, lifelike image quality that utilizes the smallest hardware footprint in the industry.
ESI 7 - Advanced Classifier (2003 - 2005 )
The ESI 7's new neural network based classifier technology automatically organizes defects into meaningful groups. It offers a powerful tool to establish the reason behind the defect.
ULMA NTi - 1st photographic imaging system (1999 - 2003 )
The fast CCD camera technology and powerful signal processing enables ULMA NTi to "see" the nature of individual defects, in addition to their shape. By assessing defect attributes, operators are able to conclude what caused the defect and thus initiate corrective actions.
ULMA 3D with AUI/PC based operator interface (1993-1997)
Industrial PCs were integrated into ULMA 3D in 1993 at the same time as for ULMA 2000. The system included complete history features and advanced quality history and quality analysis, providing more detailed defect shape information. This system was further developed to use FPGA and RISC processor technology.
ULMA 2000 with AUI/PC based operator interface (1993-1997)
Industrial PCs were introduced as add-on options to the system in 1993. These PC-based systems provided complete history features with advanced quality history and analysis. ABB's PC based web inspection systems provided a network interface to the mill Local Area Network.
ULMA 2020/2010 (1986-1996)
In 1986, ABB introduced a new generation of phototransistor detector units and operator stations. This enabled detection and reporting of extremely small defect sizes, even on newsprint machines running at 1500 m/min.
ULMA 100/200 (1980-1985)
ULMA's visual user interface was improved when ULMA 100 was introduced in 1980. Real-time reporting was available on the advanced video monitor, which provided graphical defect maps, trends and profiles. These "living" graphics represented a breakthrough in web inspection system user interfaces. Today, ABB provides an upgrade program for all existing ULMA 100/200 systems, allowing paper mills to upgrade their existing systems to the latest technology.
ULMA I/II (1970-1979)
The system was the first commercial on-line web inspection system in the world. Early ULMA generations were based on patented phototransistor technology. Some of these installations are still on duty in paper mills today.
