[0002] The magnetic flux sensor test method is currently a very promising way to measure the cable tension of cable components. Cable tension sensors based on the magnetoelastic effect are constantly developing. Many scholars at home and abroad have optimized and proposed sensors of different concepts based on this method, and the bypass sensor is one of them.

[0003] Bypass magnetic flux sensor: The earliest prototype of the bypass cable force sensor was proposed by Ming LWANG and others abroad. Its characteristics are that the sensor magnetic pole forms a magnetic circuit with the cable component, and the sensor does not need to be pre-installed on the cable component. The research team of the Ministry of Education Key Laboratory of Optoelectronic Technology and Systems of Chongqing University proposed a design method for some parameters of the bypass cable force sensor and manufactured a single bypass cable force sensor. Liu Xiaoliang improved the single bypass sensor and proposed a double bypass magnetic flux sensor.

[0004] Although the research on bypass magnetic flux sensors has been deepening in recent years, it still faces the following problems:
