[0002] A weighing sensor is actually a device that converts a mass signal into a measurable electrical signal output. When using a sensor, the actual working environment where the sensor is located should be considered first. This is crucial for correctly selecting a weighing sensor, as it relates to whether the sensor can work properly, its safety and service life, and even the reliability and safety of the entire weighing scale.

[0003] Chinese Patent No. CN214372833U discloses a new type of high-precision weighing sensor, which relates to the technical field of weighing sensors. The utility model includes a first stress block, a stress sensor, a second stress block and a bottom plate. The stress sensor is in extrusion fit with both the second stress block and the first stress block. A circular hole and a conduction column are arranged on the upper surface of the first stress block. The conduction column passes through the circular hole, and a rotating ball is fixedly connected to the upper surface of the conduction column. A surrounding block is arranged on the circumferential side of the rotating ball. By setting the rotating ball and further sleeving a surrounding block that can rotate omnidirectionally around the rotating ball on the whole body of the rotating ball, when the object to be weighed is pressed down at different angular directions, the flexible rotation of the surrounding block can adapt to the omnidirectional weighing force conduction, increasing the accuracy and adaptability of this weighing sensor. By setting a sliding block to filter out impurities and dust in the slide rail, it is ensured that the first stress block maintains its original weight to the greatest extent to increase the weighing accuracy.
