The whole reason for having Torque Transducer is to be able to weigh your loads sufficiently and accurately, so when they are not giving us the accuracy we expect, it leaves us wondering just what is affecting the accuracy of our equipment. Well, there are a number of reasons as to why your load cell & torque sensors are not providing the high level of accuracy that you would expect, with each of them being listed here.
The Precision in the Load Cell & Torque Sensors – First thing you should be doing if you are chasing accurate weighing accuracy is to select a excellent load cell & torque sensors manufacturer. While all manufacturers will proclaim their products offer high levels of accuracy, only the top brands will often have the ability to provide you with the best accuracy.
A great load cell as well as its torque sensors will usually have good response times (how quickly they offer an exact reading), will never react to much to temperature alterations in environmental surroundings, is not going to suffer from creep (a change in the reading after 2-3 minutes of being stationary), and can have really low ‘nonrepeatability’ (variations in the readings for the very same load after repeated loadings).
Factors with the Load – The precision of any load cell & indicator reading may be afflicted with how the load is positioned on the weighing system. To make sure an accurate reading, the burden has to be placed on each cell properly so that as specified from the manufacturer.
In case a load has become applied poorly, including the load being twisted, the cell and weighing system will only throw up inaccurate results. To make sure complete accuracy when weighing, the stress has to be placed in a way which are supporting each of the weight proportionally.
Outside Forces – One other reason why accuracy could be affected on Compression Load Cell is definitely the many outside forces that could be slightly altering the body weight force. Wind, shock loading, vibration, and alterations in temperature can all come with an effect on the true accuracy of the reading.
A cross-wind may have an effect that the load feels lighter than it really is while shock is the method of wearing more load weight than what the load capacity of the cells are. Vibrations from other nearby machines can also omqzxd fluctuations in a weight whilst temperature modifications in the surroundings may cause materials within the load to either expand or contract.
Signal Interference – The last method by which the accuracy in the weight of a load might be affected is thru interference with the signal transmission. The load cell electrical signal could be suffer from interference from radio frequencies, electromechanical interference, and even moisture within the air may cause interference towards the electrical signal.
Summary – So to guarantee that 3 Axis Load Cell are as accurate as possible; you need to be knowledgeable of exactly what could affect that accuracy and place measures in position to prevent those occurrences from happening. Just use the most effective manufacturers of load cells & torque sensors leading brands, load them correctly, make sure that outside forces are limited, and that there is very little possibility of signal interference.
