Garbage, mud, stones, and other debris on the truck scale can affect its weighing accuracy. The specific impact can be explained from the following points:
1. Interference with normal force on the sensor
Garbage or debris stuck between the weighing platform and the foundation can cause the sensor to not fully bear the weight of the vehicle, resulting in weighing deviation.
In severe cases, it may form an "overhead" phenomenon, which prevents some weight from being transmitted to the sensor.
2. Causing uneven force distribution on the platform
If debris is concentrated in a corner, it will cause the weighing platform to tilt or experience unilateral force, resulting in unstable weighing data or increased errors.
Multiple weighing results are inconsistent, which affects the efficiency and credibility of the operation.
3. Causing zero drift
Long term accumulation of debris under the weighing platform can cause abnormal changes in the zero point of the weighing instrument, resulting in the so-called 'zero drift' phenomenon.
The initial value of each weighing is different, which affects the cumulative weighing or weighing statistics.
4. Increase the wear and tear of the limit device
Clamping the limit device with sediment and stones can cause limit impact, wear, or jamming, which in turn affects the normal expansion and contraction of the weighing instrument and its weighing response.
Long term failure to clean may also result in damage or deformation of the limiter.
5. Impact on equipment lifespan
Sludge or stones contain water and corrosive components, which can easily cause rusting, short circuits, or damage to sensors.
The structure of the weighing platform is also prone to moisture and corrosion, reducing its service life.
6. Safety hazards
Larger stones may cause the vehicle to bounce or slip when weighing up and down, posing a safety issue.
If the platform is blocked with mud, freezing in winter may also affect the recovery position of the platform or cause structural damage.
