The entire point of having Torque Transducer is to be able to weigh your loads sufficiently and accurately, so when they are not giving us the accuracy that we expect, it leaves us wondering just what could be affecting the precision of our equipment. Well, there are a number of reasons as to why your load cell & torque sensors are not offering the high level of accuracy that you would expect, with each of them being listed here.
The Precision from the Load Cell & Torque Sensors – First thing you should be doing when you find yourself chasing accurate weighing accuracy is always to select a high quality load cell & torque sensors manufacturer. While all manufacturers will proclaim that their products offer high amounts of accuracy, only the top brands will most likely have the ability to provide the best accuracy.
A great load cell along with its torque sensors will generally have good response times (how fast they give an accurate reading), will not react to much to temperature modifications in the environment, will never suffer from creep (a modification of the reading after 2-3 minutes of being stationary), and can have really low ‘nonrepeatability’ (differences in the readings for the very same load after repeated loadings).
Factors with all the Load – The accuracy of any load cell & indicator reading could be affected by how the load is placed on the weighing system. To ensure an exact reading, the load must be placed on each cell properly so when specified from the manufacturer.
When a load has become applied poorly, including the load being twisted, the cell and weighing system is only going to throw up inaccurate results. To ensure complete accuracy when weighing, the load has to be placed in a way that are supporting all of the weight proportionally.
Outside Forces – One more reason as to why accuracy may be affected on Miniature Load Cell is the many outside forces that may be slightly altering the body weight force. Wind, shock loading, vibration, and modifications in temperature can all come with an effect on the true accuracy of any reading.
A cross-wind can have an effect that the load feels lighter than it really is while shock is the process of putting on more load weight than what the weight capacity from the cells are. Vibrations from other nearby machines could also omqzxd fluctuations in a weight whilst temperature changes in the surroundings may cause materials in the load either to expand or contract.
Signal Interference – The last way in which the precision in the weight of any load may be affected is thru interference with the signal transmission. The stress cell electrical signal can be suffer with interference from radio frequencies, electromechanical interference, as well as moisture inside the air could cause interference for the electrical signal.
Summary – So to guarantee that Multi Axis Load Cell are as accurate as possible; you need to be knowledgeable of exactly what could affect that accuracy and put measures set up to avoid those occurrences from happening. Just use the most effective manufacturers of load cells & torque sensors leading brands, load them correctly, ensure that outside forces are restricted, and that there is very little probability of signal interference.
