Sensor protection device for small-capacity high-precision weighing module

The utility model provides a sensor protection device for a small-capacity high-precision weighing module, which comprises a wedge-shaped clamping mechanism and a protection shell, the wedge-shaped clamping mechanism is clamped on the shell wall surface of the weighing module, the wedge-shaped clamping mechanism and a scale pan on the weighing module are arranged at an interval, the protection shell covers the scale pan, and the wedge-shaped clamping mechanism is clamped on the shell wall surface of the weighing module. And the protective shell is fixedly connected with the wedge-shaped clamping mechanism. According to the utility model, external protection of a small-capacity high-precision weighing module sensor is realized, and vertical, horizontal and torsion abnormal loads can be resisted. A wedge-shaped clamping mechanism is designed, the IP grade of the module is not affected in use, and meanwhile the problem that an external protection device of a weighing module sensor is difficult to fix is solved.
