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 weighing scale accuracy.


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


  • 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 estimated 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.


  • Wind loading: Mostly the indoor scales are affected by the air movement created by air conditioners and air pipes
  • Vibration: Vibrations 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 shown according to the difference in pressure of the  environment with the calibration environment
  • Shock loading: Unloading heavy materials out suddenly on your weighing scales can put more power than the most extreme evaluated limit and harm the system or the load cells.


  • 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 placed appropriately can cause load cells to decipher the power as weight and produce wrong readings.
  • An inappropriately applied load, for example, a turning load, may bring about incorrect weight.


  • Moisture: In the load cell difference in the environment causes moisture will occur and enter the system. This will cause the clubbing of electrical input and output  and result in inaccurate  displaying of output
  • Temperature: When the load cell is subject to temperature leads to some problems like when an increase in temperature is inversely proportional to wire resistance. This will result in a 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
