The entire point of using a load cell & torque sensor is so that you can weigh your loads sufficiently and accurately, so if 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 which you would expect, with each of them being shown below.
The Precision from the Load Cell & Torque Sensors – First thing you should be doing if you are chasing accurate weighing accuracy is to decide on a excellent multi axis load cell manufacturer. While all manufacturers will proclaim their products offer high amounts of accuracy, just the top brands will often have the ability to deliver the best accuracy.
A great load cell and its torque sensors will normally have good response times (how fast they give a precise reading), will not react to much to temperature alterations in environmental surroundings, is not going to suffer from creep (a modification of the reading after 2-3 minutes of being stationary), and definately will have really low ‘nonrepeatability’ (variations in the readings for the similar load after repeated loadings).
Factors with the Load – The accuracy of any load cell & indicator reading could be impacted by just how the load is positioned on the weighing system. To make certain a precise reading, the load needs to be put on each cell properly so that as specified through the manufacturer.
If a load has been applied poorly, such as the load being twisted, the cell and weighing system will only throw up inaccurate results. To make sure complete accuracy when weighing, the burden must be placed in such a way that are supporting all of the weight proportionally.
Outside Forces – One other reason as to why accuracy may be affected on torque sensor will be the many outside forces that might be slightly altering the weight force. Wind, shock loading, vibration, and alterations in temperature can all provide an effect on the true accuracy of any reading.
A cross-wind might have an effect the load feels lighter than it actually is while shock is the method of using more load weight than what the body weight capacity of the cells are. Vibrations using their company nearby machines dzrgzs also cause fluctuations in a weight whilst temperature alterations in the surroundings could cause materials inside the load either to expand or contract.
Signal Interference – The final method by which the accuracy from the weight of any load could be affected is thru interference with the signal transmission. The load cell electrical signal can be suffer with interference from radio frequencies, electromechanical interference, and even moisture inside the air could cause interference for the electrical signal.
Summary – So to make sure that load cell are as accurate as is possible; you need to be knowledgeable of precisely what could affect that accuracy and put measures set up to prevent those occurrences from happening. Simply employ the most effective manufacturers of load cells & torque sensors leading brands, load them correctly, make certain that outside forces are restricted, and that there is very little chance of signal interference.
