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.
