AI Technical Summary
Existing technologies are insufficient for effectively testing and calibrating large weighing tanks. Traditional methods require suspending heavy weights or fixing structures, which are cumbersome and unsuitable for large tanks.
A mobile detection device is adopted, including a frame, a tank, a sensor under test, and a mobile detection component. Detection is performed using a hydraulic cylinder and a standard sensor. A standard force value is applied through a hydraulic servo system, and the force value change of the sensor is recorded to achieve calibration.
It enables rapid and accurate testing and calibration of weighing tanks, is applicable to different tanks, requires no fixed installation, improves testing efficiency and accuracy, and reduces maintenance difficulty and cost.
