Factors That Can Affect the Accuracy Of Weighing Scale

There are mainly three factors that affect the accuracy of the weighing scale. If you find any inaccuracy in your weighing machine, you should take these factors into consideration and make adjustment accordingly. For additional information you have you contact your weighing system provider.
Weighing Scale

1. Environment

There is a number of environmental factors that can affect the accuracy of scale by adding more force to the applied load and load cell:
Wind: Outdoor and even some indoor systems can be affected by air. A sensitive indoor weighing system could be affected by air created by AC or air ducting etc.
Shock: Dumping heavy product or material suddenly on a weighing scale can put more force than the maximum capacity and can also damage the system or the load cells.
Vibration: Sensitive load cells can interpret vibrations from nearby equipment as additional force and can result in an incorrect result.
Pressure: Weighing scale can lead to result inaccurately if the pressure of the operating environment is different from the calibration environment.

2. Load Cell Accuracy

The load cell is a major weighing component of all weighing scales and a malfunctioning load cell can result in inaccurate weights.
In order to understand load cell functionality and its impact on weighing machine, there is a numerous performance parameter that you should be familiar with:
Nonlinearity: The maximum deviation of a load cell’s calibration from a straight line, listed between zero-weight and maximum capacity.
Hysteresis: The difference in outputs when the same load is applied two times.
Creep: The change in weight when a load is left stationary for a long time.
Temperature: If the load cell exposes it to significant temperature variations, its accuracy can be affected.
Response Time: The time taken by load cell to settle and to give an accurate reading. Response time is a major cause for errors if the load cell is repeatedly used for weighing process with little time between weights.

3. Interference

Load cells work by sending an electrical signal that is further processed by a controller, which then sends outputs to the result display as the measured weight. Any interference to the electrical signal at any point can lead to an inaccurate result.
RFI & EMI: They can create ‘noise’ or additional input signals that can cause the controller to show incorrect output.
Moisture: Cables can absorb moisture and condensation, causes the electrical output to get coupled with the input signal. This creates extra interference in the signals.
Temperature: Cable resistance increases with rising in temperature and causes the voltage to drop, which results in the controller displaying wrong results than the load cell generated.

Best Load Cell For Your Weighbridge (Dharam Kanta)

Image
We all know that the  load cell  is the most important component of any  weighbridge  (Dharam Kanta). So, while buying a load cell it is necessary that we go for the one which is best for your weighbridge. Because this can affect the number of things in your business-like failure of maintenance, peak time failure, workload, increase in cost, increase in maintenance cost etc. Keli Load Cell To avoid all such issue, it is advised to use the best load cell in your weighbridge ( Dharam Kanta ). A load cell is considered as a heart of  weighing scale  or any weighing equipment so, it is good to keep your heart (load cell) well or error-free for the best run and result. As we weighbridge is a kind of large  weighing machine  used to weigh heavy-duty vehicles. In India, money plays an important role. So, the customer cannot buy costly products. But you have no need to worry, we have an optimized solution for you i.e.  Keli Load C...

5 Advancements in Mobile Weighbridge

Image
Mobile weighbridge  was bought in the market after various industrial requirement. These  weighbridges  are highly versatile and can be moved easily from one place to another. They are generally used to weigh heavy-duty vehicles like truck, trailer, pick-up for weighing the loads that these vehicles carry. Over the year, mobile weighbridge has made numerous technological development that allowed them to be more efficient and accurate. mobile weighbridge 1.   Evolved Design Options There is mainly two type of mobile weighbridge- portable axle truck scale and wheel weighing truck scale. Each design offers various benefits to the users who are integrating the truck scale into their weighing process. Axle based weighbridge allows weighing inputs in a rough and rugged environment which demand a heavy-duty weighing scale. On the other hand, wheel weigher truck scale help in calculating and managing the weight load with great versatility as compared to axle ...
