The whole point of using a load cell & torque sensor is so that you can weigh your loads adequately and accurately, so while they are not giving us the accuracy that we expect, it leaves us wondering just what could be affecting the accuracy of our equipment. Well, there are a variety of reasons as to why your load cell & torque sensors are not offering the top level of accuracy that you would expect, with each of them being listed below.
The Accuracy in the Load Cell & Torque Sensors – First thing you need to be doing if you are chasing accurate weighing accuracy is to pick a top quality 3 axis load cell manufacturer. While all manufacturers will proclaim that the products offer high degrees of accuracy, just the top brands will often have the ability to deliver the best accuracy.
A good load cell along with its torque sensors will normally have good response times (how quickly they provide an exact reading), will not react to much to temperature modifications in the environment, is not going to suffer from creep (a change in the reading after 2-3 minutes of being stationary), and can have very low ‘nonrepeatability’ (differences 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 how the load is put on the weighing system. To ensure an exact reading, the load must be applied to each cell properly so that as specified through the manufacturer.
When a load continues to be applied poorly, such as the load being twisted, the cell and weighing system will simply throw up inaccurate results. To ensure complete accuracy when weighing, the load needs to be placed in a way which are supporting all of the weight proportionally.
Outside Forces – Another reason why accuracy might be affected on torque sensor will be the many outside forces that may be slightly altering the load force. Wind, shock loading, vibration, and modifications 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 actually is while shock is the method of using more load weight compared to what the weight capacity of the cells are. Vibrations from other nearby machines dzrgzs also cause fluctuations in a weight whilst temperature modifications in the surroundings can cause materials in the load either to expand or contract.
Signal Interference – The final manner in which the accuracy from the weight of a load might 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 within the air may cause interference to the electrical signal.
Summary – So in order to ensure that load cell are as accurate as possible; you ought to be well aware of just what could affect that accuracy and set measures in place to stop those occurrences from happening. Simply use the best manufacturers of load cells & torque sensors leading brands, load them correctly, make certain that outside forces are restricted, and this there is little probability of signal interference.
