Cable Tension Sensor Based on Magneto-elastic Effect
This article introduces a sensor based on magneto-elastic effect in order to measure the axial tension of steel cable. We explained the basic principle of the sensor in detail, designed and analyzed the magnetic circuit structure with single magnetic loop. We propose a kind of device based on the pulse magnetization circuit of the steel cable and present the experiment results .Our results indicate that the system is in accordance with theory and it is stable and reliable. The device is battery-powered, small, cheap and portable.
