The sleeve cable force sensor based on magnetoelastic effect has developed rapidly in recent years, and has been widely used in the field of bridge cable force measurement in China. Existing sleeve cable force sensor needs to be installed at the beginning of construction, so it is difficult to reinstall them later, and its long-term performance is also difficult to evaluate and measure online. To solve this problem, the tension measurement of the designed by-pass excitation cable force sensor is carried out, and the influence of signal line length and ambient temperature on the measurement results is analyzed. The results show that the designed by-pass excitation cable force sensor has high linearity, which is expected to solve the problem of the existing sleeve cable force sensor.
