Description
technical field [0001] The invention relates to a weighing sensor, more specifically, to a weighing sensor suitable for electronic balances. Background technique [0002] The electromagnetic force balance weighing sensor is the core component of the electronic balance, and its quality has a decisive impact on the performance of the electronic balance. At present, domestic electromagnetic force weighing sensors are mainly traditional split front-mounted sensors. Their principles and processes are relatively mature at the theoretical level, but there are still the following problems in actual production and use: large volume and heavy weight. Although it is much smaller than the rear-mounted sensor, it is still difficult to realize the light weight and miniaturization of the electronic balance when it is used as the sensor of the electronic balance; the structure is complex, there are many parts, the requirements for the assembly personnel are very high, and the consistency of...
