Wheel spoke weighing sensor KJT-LF/WY-105

The spoke type weighing sensor is of constant magnetic flux type, and the constant magnetic flux magneto electric sensor is composed of magnets (magnetic steel), coils, springs, metal frames, and shells. The weighing sensor system generates a constant DC magnetic field, and the working air gap in the magnetic circuit of the spoke type weighing sensor is fixed, so the magnetic flux in the air gap is also constant. Weighing sensors with spoke type weighing sensors can have coils as their moving parts, and can be divided into two structural types: coil type or moving iron type. The schematic diagram of the structure of the constant flux magneto electric sensor shows that the magnet is fixed to the sensor housing, and the coil and metal frame (collectively referred to as the coil assembly) of the spoke type weighing sensor are supported by soft springs. The coil assembly of the spoke type weighing sensor is fixed to the housing, and the permanent magnet is supported by a soft spring. The damping of both is generated by the relative motion between the metal skeleton and the magnetic field

The coil assembly of the spoke type weighing sensor is fixed to the housing, and the permanent magnet is supported by a soft spring. The damping of both is electromagnetic damping generated by the relative motion between the metal skeleton and the magnetic field. The working principle of the moving coil type and the moving iron type is completely the same. When the shell vibrates together with the measured vibrating body, due to the soft spring, the mass of the moving parts is relatively large. Therefore, when the vibration frequency is high enough (far higher than the natural frequency of the sensor), the inertia of the moving parts is large, and there is no time to vibrate together with the vibrating body, almost stationary. The vibration energy is almost completely absorbed by the spring, and the relative motion speed between the permanent magnet and the coil is close to the vibration speed of the vibrating body. The relative motion between the coil and the magnet causes the coil to cut magnetic field lines, and the spoke type weighing sensor generates an induced electromotive force proportional to the speed of motion. The number of turns of the coil in the working air gap magnetic field is called the working turns; Magnetic induction intensity in the working air gap; The average length of each coil turn.
