Cost-oriented sensor concept for magnetostrictive force measurement and its material requirements

Abstract. A cost-oriented sensor concept based on the conversion principle of inverse magnetostriction is presented. The main element of the concept is a disc-shaped sensor enclosing a remanent magnetization, which will give rise to an externally measurable magnetic field changing under a load. The magnetic properties of a commonly used cold working steel as one potential sensor material under soft-annealed and hardened conditions are analysed and discussed regarding their impact on sensor performance.
