The first Pressductor transducer was developed in Västerås, Sweden, in the early 1950's and patented in 1954
ABB's well-known Pressductor® Technology. is a measurement principle based on the magnetoelastic effect - the magnetic properties of a material are influenced by the mechanical force applied to it.
When exposed to mechanical force, ABB's Pressductor transducer produces measurement signals as a result of changes in magnetic fields. (Move your mouse over the illustration to see these changes.) Because these signals are not contingent upon physical movement or deformation, the load cells combine sensitivity with extraordinary tolerance to overloads and virtually no built-in limit to the number of load cycles.
The ABB Pressductor transducers produces high-power, low-impedance AC signals that are very resistant to electrical interference and earth faults.
ABB's Pressductor transducer stands for unbeatable load cell performance, thanks to its unique combination of accuracy, overload capacity and ability to withstand harsh environments. By using this technology you will achieve higher quality and reliability, especially under demanding conditions.
