Motion and Force Control
We deliver electro hydraulic positioning systems to the saw mill industry and special application to other industries. From design of components and systems to service and installation. We have unique experience in this field based on our long history and several thousand of systems delivered. By combining our expertise of positioning with our force measurement technology we have delivered systems for force and positioning.
Our CPU-based electronic systems can communicate with host PC/PlC systems via fieldbus. Control parameters and calibration values are set up through terminal programs in a PC-based environment. Our control system for sawmill machinery can be found in most countries with a lumber industries. Over the years, we have shipped control systems for thousands of axes. Vishay Nobel systems for controlling web tension, roll pressure, reeling, and disc gaps in pulp and paper operations and cellulose operations are known worldwide. Our systems are ideal for use with industrial machines with high set speeds and wide operating ranges that require high set forces. All systems are factory calibrated and ready to be put into operation immediately after installation.
The development of electro-hydraulic systems started in the 1940s. initially they were used to control artillery guns (Bofors). Subsequent development involved systems for sawmill applications.
