The whole point of having lots cell & torque sensor is to be able to weigh your loads sufficiently and accurately, so when they’re not giving us the accuracy that people expect, it leaves us wondering precisely what could possibly be affecting the accuracy of our equipment. Well, there are a number of reasons as to the reasons your load cell & torque sensors are not providing the high level of accuracy that you would expect, with each of them being listed below.
The Accuracy of the Load Cell & Torque Sensors
The very first thing you need to be doing when you are chasing accurate weighing accuracy is to select a excellent load cell & torque sensors manufacturer. While all manufacturers will proclaim that their products offer high levels of accuracy, only the very best brands will usually be able to deliver the best accuracy.
A good load cell and its own torque sensors will generally have good response times (how quickly they provide an accurate reading), won’t respond to much to temperature changes in the surroundings, will not suffer with creep (a big change in the reading after 2-3 minutes of being stationary), and will have very low ‘nonrepeatability’ (differences in the readings for the 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 placed on the weighing system. To make sure an accurate reading, the load has to be put on each cell properly so when specified by the manufacturer.
If a load has been 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 such a way that are supporting each of the weight proportionally.
Another reason as to the reasons accuracy might be affected on a load cell & torque sensor may be the many outside forces that may be slightly altering the weight force. Wind, shock loading, vibration, and changes in temperature can all have an effect on the real accuracy of a reading.
A cross-wind can have an impact that the load feels lighter than it really is while shock is the procedure for putting on more load weight than what the weight capacity of the cells are. Vibrations from other nearby machines can also cause fluctuations in a weight whilst temperature changes in the environment can cause materials in the strain to either expand or contract.
The final manner in which the accuracy of the weight of lots could be affected is through interference with the signal transmission. The load cell electrical signal can be experience interference from radio frequencies, electromechanical interference, and even moisture in the air can cause interference to the electrical signal.
So in order to make sure that your load cell & torque sensors are as accurate as you possibly can; you should be well aware of just what could affect that accuracy and put measures in place to avoid those occurrences from happening. Simply utilize Loadcell of load cells & torque sensors leading brands, load them correctly, ensure that outside forces are limited, and that there is little chance of signal interference.
