At CUBLiFT, we understand the importance of your floor scale for the success of your operations by providing accurate and dependable weighing measurements.
Even with the highest quality floor scales, there are factors that can affect the accuracy of your weighing system by damaging its quality and performance.
Taking advantage of our expertise and knowledge can help you determine how and where to install your floor scale and what factors can affect its operation.
Here we list 7 factors that affect your floor scales quality:
1. Floor Scale Weigh Load Cell Accuracy
Weigh Load cell technology of your floor scale defines its weighing accuracy and precision.
It’s the most important part of your digital weighing scale.
A malfunctioning weigh load cell or weigh modules in the machine can result in inaccurate weighing measurements.
In order to determine the source of your floor scale manufacturing, it’s essential to be familiar with the following performance elements:
- Response Time: Using your floor scale repeatedly with little time between weighing sessions sometimes can cause errors.
- Nonlinearity: The non-linearity of the load cell specifies the maximum deviation minus or plus of the calibration curve from a straight line drawn between the zero and rated load outputs.
- Creep: When the floor scale is left stationary for a long period of time, it can cause a change in the measured weight.
- Hysteresis: It refers to the measurement difference in your floor scale when the same load is measured twice.
- Temperature: Extreme temperatures can lead to inaccurate measurements.
- Non-repeatability: It’s the maximum difference between the repeated readings of how repeatedly a material is loaded under identical conditions onto a floor scale.
- Gravitational Effect: Different floor scales react differently when used in different locations as gravity is not the same everywhere. Whenever it happens to your floor scale, it requires calibration to output accurate measurements.
2. Floor Scale Load Factors
Sometimes, it’s not the load cells but rather the load on the scale itself and how it was supported that can cause inaccurate weighing.
We can eliminate this by keeping an eye out for the following things:
- Ensuring the mounting structure supports the scale, its components, and its load without flexing
- Properly aligning the load
- Ensuring a stable loading
- Ensuring the proper installation and functioning of floor scale
- Ensuring a direct channel of the load on load cell through the mounting hardware
3. Floor Scale Environmental Factors
Anything in the vicinity of your floor scale can impact its accuracy, such as:
- Vibration: Vibrations can disturb the weighing accuracy of your floor scale by affecting its hardware.
- Shock Loading: Suddenly dropping or placing heavy loads on your floor scale can result in shock loading that leads to damaging the load cells or the complete weighing scale system.
- Unclear Scales: Cleaning your scale is important because not doing so can lead to the build-up of dirt and other objects.
- Wind Loading: Air movement can affect the accuracy of your scale.
- Air Pressure Differences: If the air pressure in the operating environment is different than the air pressure from the calibration environment, it can lead to inaccurate measurements.
The following factors can cause interference that can affect the ability of your floor scale to display accurate weight readings:
- Moisture: Moisture build-up is a potential reason behind affecting the accuracy of your floor scale by causing interference in the signals being sent from the load cells to the display indicator.
- Temperature: Wire resistance increase with the increase in temperature and can cause the voltage drop that leads to displaying inaccurate results.
- RFI and EMI: RFI (Radio Frequency Interference) and EMI (Electromechanical Interference) are both electrical noise sources that can affect the weighing accuracy of your floor scale.
5. Floor Scale Maintenance
Any floor scale can result in general wear and tear from its regular use.
By maintaining your scale regularly, you can prevent the following issues from worsening:
- Calibration: Calibrating your floor scale once a year can ensure accurate and precise weighing measurements.
- Old Parts: Wear and tear can cause parts to become inaccurate and replacing them is the only best option.
- Damaged Parts: Even well-protected floor scales at some point be damaged and can cause inaccurate readings.
- Damaged Connections: A faulty cable or wireless connection between load cells and the weighing scale can lead to inaccurate weighing measurements to display.
6. User Error
Human error can cause issues and can be a source of inaccurate weighing.
- Cluttered Work Space: A cluttered workspace can impact the accuracy of your floor scale.
- Magnets: Some floor scales can contain magnets and placing other magnets near them can result in faulty/inaccurate readings.
- Slope: Floor scale requires a stable and level surface to perform accurately.
7. Instrumentation and Control
Eliminating the following can clean up less-than-perfect weight signals and improve your scale’s weighing accuracy:
- Electrical noise sources
- Mechanical noise sources
- Mechanical force,
A signal from your load cell to the weighing controller can cause errors if unclean or interrupted.
Above are some of the factors which possibly affect your floor scale accuracy as per experience. we are open and welcome you to join the discussion.
