摘 要：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.
