[0002] A weighing sensor is a device that converts a mass signal into a measurable electrical signal output, and is widely used in various weighing and measurement systems. There will be certain errors at the four corners and the center of the weighing sensor. A weighing sensor error measurement and control device is a special equipment for measuring and controlling the errors at the four corners of the weighing sensor;

[0003] After retrieval, the patent number is CN203908660U, which discloses a weighing sensor four-corner error measurement and control device. The weighing sensor four-corner error measurement and control device has functions such as rotation speed, rotation angle setting, motor status, and working status monitoring of each loading cylinder, loading position display, and position protection. The touch screen can display and set the rotation angle and rotation speed of the motor; it can realize the free switching between manual control and foot control; the device has a simple structure, high integration, and low cost, and is suitable for various types of four-corner calibration equipment; however, this device measures and controls the four corners of the weighing pan, not directly measuring and controlling the four corners of the weighing sensor body. Although this method can reflect the overall performance of the weighing system, it may not be able to directly and accurately locate the error conditions at the four corners of the sensor. For this reason, we propose a weighing sensor error measurement and control device. Summary of the Invention

[0024] During use, after measuring at the center of the weighing sensor 22, the data will be displayed in the control box 2. Then, the first motor 6 is started through the control box 2, causing the first motor 6 to drive the first screw rod 5 to rotate inside the measurement and control box 1. At this time, when the first screw rod 5 rotates, it will drive the moving plate 3 to slide to the left on the sliding plate 4. Then, when the moving plate 3 moves, it will drive the weighing sensor 22 above to move together, and stop when the right side of the weighing sensor 22 is displaced to the center below the weighing plate 23.

[0028] Specifically, when it is necessary to clamp the weighing sensor 22, the third motor 13 is started through the control box 2, so that the third motor 13 drives the bidirectional screw 14 to rotate inside the clamping box 12. At this time, when the bidirectional screw 14 rotates, it will drive the first movable plate 15 and the second movable plate 16 to move in opposite directions.
