Abstract
Magneto-elastic cable tension sensor have a number of advantages, it will be ideal method to measure cable tension in large span cable-bridge, but the sensor is sensitive to temperature, so the temperature influence is not negligible to sensor. In this paper, the principle of cable tension sensor based on magnetic-elastic effect is introduced, the common temperature compensation technique are detail analyzed. A novel method of temperature compensation by adjusting the bias magnetic field is put forward, by theoretical analysis and experiment, indicated that it is feasible to compensated the temperature influence.
