Weighing Scale Accuracy

Factors that affect the weighing scale Accuracy

Accuracy is the most important factor in current engineering technology. When it comes to the manufacturing process ensure our product will work properly. The quality of the product is one of the other factors we have to consider. Here in this blog, we can discuss the factors affecting the weighing scale accuracy.

The  top 4 factors that affect the weighing scale accuracy  are

        • Load Cell Accuracy
        • Environmental  Factors
        • Load Issues Factors
        • Interference

Load Cell Accuracy

    • Nonlinearity: The most extreme deviation of a load cell’s alignment curve from a straight line.
    • Hysteresis: The difference in scale output when a similar load is estimating twice when expanding from a Zero-weight, and a second estimation that is decreasing from the load cell’s maximum weight rating.
    • Creep: The change in the measured weight when an object is left stationary for a long period of time.

Environmental  Factors affect weighing scale accuracy

    • Wind loading: Mostly the indoor scales are affected by the air movement created by air conditioners and air pipes
    • Vibration: Vibrations are also create issues from nearby equipment that cause misinterpretation of weight readings.
    • Unclean scales: The weighing scale shows incorrect readings due to the scales are regularly not cleaning.
    • The difference in Pressure: The pressure difference is showing according to the difference in pressure of the  environment with the calibration environment
    • Shock loading: Unloading heavy materials out of suddenly on your weighing scales can put more power than the most extreme evaluated limit and harm the system or the load cells.

Load Issues Factors

    • Another thing that causes incorrectness in the weighing system is the manner in which load is applied and upheld. 
    • Ensure the mounting hardware functioning properly.
    • Loads that are not placing appropriately can cause load cells to decipher the power as weight and produce wrong readings.
    • An inappropriately applied load, for example, turning load, may bring about incorrect weight.


    • Moisture: In the load cell the difference in the environment causes moisture will occur and enter the system. This will cause the clubbing of electrical input and output  and results  inaccurate  displaying output
    • Temperature: When load cell subject to temperature leads to some problems like when an increase in temperature inversely proportional to wire resistance. This will result in voltage drop  and shows incorrect readings
    • RFI and EMI: The source of these signals are lightning, portable static electricity, solenoids, etc. This noise will also lead to incorrect measurement readings in the system

Picking quality components that particularly fit your application will go far toward guaranteeing that your framework gives the precision you need. In this blog, we have described the main five factors so you can prevent issues in your weighing scale accuracy
