The entire point of having a load cell & torque sensor is to be able to weigh your loads effectively and accurately, so while they are not giving us the precision 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 high level of accuracy that you would expect, with each of them being shown below.
The Precision in the Load Cell & Torque Sensors – The very first thing you ought to be doing when you find yourself chasing accurate weighing accuracy is always to select a high quality multi axis force sensor manufacturer. While all manufacturers will proclaim their products offer high levels of accuracy, just the top brands will often be able to deliver the best accuracy.
A great load cell and its torque sensors will generally have good response times (how quickly they give a precise reading), is not going to react to much to temperature modifications in the environment, will not suffer from creep (a change in the reading after 2-3 minutes to be stationary), and definately will have really low ‘nonrepeatability’ (differences in the readings for the very same load after repeated loadings).
Factors with the Load – The accuracy of a load cell & indicator reading can be affected by how the load is put on the weighing system. To make sure an accurate reading, the burden has to be applied to each cell properly so that as specified from the manufacturer.
In case a load continues to be applied poorly, like the load being twisted, the cell and weighing system is only going to throw up inaccurate results. To ensure complete accuracy when weighing, the stress must be placed in a way that are supporting all of the weight proportionally.
Outside Forces – Another reason as to why accuracy could be affected on torque sensor will be the many outside forces that may be slightly altering the weight force. Wind, shock loading, vibration, and modifications in temperature can all provide 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 using more load weight than what the body weight capacity of the cells are. Vibrations from other nearby machines dzrgzs also cause fluctuations in a weight whilst temperature alterations in the surroundings may cause materials within the load to either expand or contract.
Signal Interference – The final way in which the accuracy in the weight of a load might be affected is through interference with the signal transmission. The burden cell electrical signal could be suffer with interference from radio frequencies, electromechanical interference, as well as moisture in the air may cause interference for the electrical signal.
Summary – So to guarantee that load cell are as accurate as you can; you should be well aware of exactly what could affect that accuracy and place measures set up 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 limited, which there is very little probability of signal interference.
