Magnetoelastic Sensors - Status, Commercial Readiness, and Outlook

摘要

Torque/load sensors will play an increasingly important role in many applications, provided that functional requirements and cost targets for serial production are met. They enable critical benefits such as efficiency improvements, weight savings, operational safety, enhanced productivity, and cost savings. Magneto-elastic sensors, being truly non-contact based, have inherent advantages over traditional solutions based on strain gauges regarding robustness and cost structures. Recently, they have emerged as a viable, commercially proven alternative in a number of industry sectors with demanding requirements. The technical and commercial readiness level of magneto-elastic sensor technology is presented and discussed in this presentation. Also, an outlook is presented regarding recent developments in making magneto-elastic sensor technology applicable to non-magnetic metals.
