The whole point of having load weighing equipment is to be able to weigh your loads sufficiently and accurately, so when they are not giving the accuracy that you expect, it might leave you wondering what could be affecting the accuracy of the equipment. Well, there are some reasons why the equipment may not provide the high level of accuracy that you expect. Below are some factors that may influence the accuracy of the equipment.
Factors That Affect The Accuracy Of Load Weighing Equipment.
The Accuracy of the Equipment.
The very first thing you should do when you are chasing accurate weighing accuracy is to select a top quality weighing equipment from trusted manufacturer. While all manufacturers will proclaim that their products offer high levels of accuracy, only the top brands will usually be able to deliver the best accuracy.
A good equipment will generally have good response times (how quickly they give an accurate reading), will not react to much to temperature changes in the environment, will not suffer with creep (a change in the reading after 2-3 minutes of being stationary), and will have very low repeatability (differences in the readings for the same load after repeated loading).
How The Load Is Placed On The Weighing Equipment.
Another factor that may affect the accuracy of the reading on the equipment is how the load is put on the weighing system. To ensure an accurate reading, the load needs to be placed correctly and as specified by the manufacturer.
If the load is put poorly, such as the load being twisted, the weighing system will throw up inaccurate results. To ensure complete accuracy when weighing, the load has to be placed in such a way that it supports all of its weight proportionally.
Outside Forces
Another reason why the accuracy of the load weighing equipment may be affected is that of many outside forces that could be slightly altering the weight force. The Wind, shock loading, vibration, and changes in temperature can all affect the exact accuracy of the reading.
A cross-wind affects the reading because the load feels lighter than it is. Vibrations from other nearby machines can also cause fluctuations in weight while temperature changes in the environment can cause materials in the load to either expand or contract.
Signal Interference
The final way in which the accuracy of the weight of a load could be affected is through interference with the signal transmission. The load cell electrical signal can suffer from interference from radio frequencies, electromechanical interference, and even moisture in the air can cause interference to the electrical signal.
Summary
So to ensure that your equipment is as accurate as possible; you should be aware of what could affect that accuracy and put measures in place to prevent those occurrences from happening. Simply buy equipment from best manufacturers who make leading brands, load them correctly, ensure that outside forces are limited and that there is little chance of signal interference. It is important to note that there are many different types of scales used on weighing equipment. Use a scale that you can easily read to prevent coming up with an inaccurate reading.
