ABB's first Presductor ® The piezoelectric sensor was developed in Westerros, Sweden in the early 1950s and was patented in 1954.
The launch of this innovative sensor technology has brought a qualitative leap to the reliability of tension heads in harsh industrial environments
By using piezoelectric technology, it helps various necessary materials (such as paper and metal) achieve smoother, more uniform and consistent thickness
Presductor ® pressure magnetic sensors help improve manufacturing quality
ABB celebrates Presductor ® The 70th anniversary of the birth of piezoelectric technology, which was successfully developed in Westeros, Sweden in the early 1950s and patented in 1954. The introduction of this innovative technology provides reliable tension heads for harsh industrial environments such as paper mills and steel mills.
This innovative tension sensor was developed by Dr. Orvar Dahle from the University of California, Los Angeles (UCLA) to meet increasingly stringent industrial requirements. He was a researcher at Asea, which later became part of Asea Brown Boveri (ABB). Dr. Dahle successfully employed the magneto elastic effect, where the magnetic properties of a material are influenced by mechanical forces applied to it, thus inventing this technology.
Daniel Jonsson, Global Product Line Manager for ABB's Measurement and Analysis Business Unit, said, "The Presductor, developed in the 1950s ® The technology of pressure magnetic sensors has opened the door to a new level of production quality for enterprises. This is a revolution in accurately and stably measuring external forces, tension, pressure, and torque in harsh environments of heavy industry. This technology has created an almost perfect world of materials.
Presductor used in production and manufacturing ® Pressure magnetic sensor
From cars to machine tools, from paper products to plastic products, both consumers and businesses hope that metal strips made of steel, aluminum, or copper, as well as flexible sheets made of paper or plastic, can be perfectly smooth, consistent, and of uniform thickness. To meet these expectations, advanced and precise tension measurement technology is required.
When subjected to mechanical force, ABB's Presductor ® Magnetic pressure sensors generate measurement signals, which are the result of changes in the magnetic field. Due to the fact that these signals do not rely on physical motion or deformation, the indenter has both sensitivity and strong overload tolerance, and there is almost no limit on the number of cycles of the body load.
According to different types of indenters, this technology can naturally cope with overloads ranging from 300% to 1000% of the indenter capacity, while the deformation under typical industrial loads is only 0.02 to 0.05 millimeters. This is 10 to 100 times smaller than the displacement typically generated by sensors based on physical motion.
In contrast, other systems rely on physical motion - bending or stretching measuring elements - to generate electrical signals. The dependence on displacement makes these systems more fragile in harsh operating environments.
Over the years, piezoelectric technology has been constantly improving. For example, due to the development of materials, mechanical design, and production technology, the rated capacity of today's piezoelectric components is much lower than previous generations of products. Nevertheless, the fundamental technology at the core of the solution remains unchanged and continues to provide excellent performance in challenging applications.
