Factors THAT MAY BE Affecting the Accuracy of one’s Load Cell & Torque Sensors

The whole point of experiencing a load cell & torque sensor is to be in a position to weigh your loads sufficiently and accurately, when they are not giving us the accuracy that we expect, it leaves us wondering precisely what could 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 higher 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 top quality load cell & torque sensors manufacturer. While all manufacturers will proclaim that their products offer high degrees of accuracy, only the very best brands will usually have the ability to deliver the best accuracy.

A good load cell and its torque sensors will generally have good response times (how quickly they give an accurate reading), will not respond to much to temperature changes in the environment, will not suffer with creep (a big change in the reading after 2-3 minutes to be stationary), and will have suprisingly 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 the way the load is placed on the weighing system. To make sure an accurate reading, the strain has to be applied to each cell properly and as specified by the manufacturer.

In case a load has been applied poorly, like the load being twisted, the cell and weighing system will only throw up inaccurate results. To make sure complete accuracy when weighing, the strain has to be placed in such a way which are supporting all of the weight proportionally.

Outside Forces

Another reason as to why accuracy might be affected on a load cell & torque sensor may be the many outside forces that could 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 strain 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. Loadcell from other nearby machines may also cause fluctuations in a weight whilst temperature changes in the environment can cause materials in the load to either expand or contract.

Signal Interference

The final manner in which the accuracy of the weight of a load could be affected is through interference with the signal transmission. The strain cell electrical signal can be suffer with interference from radio frequencies, electromechanical interference, and also moisture in the air could cause interference to the electrical signal.

Summary

So in order to ensure 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 prevent those occurrences from happening. Simply use the best manufacturers of load cells & torque sensors leading brands, load them correctly, make sure that outside forces are limited, and that there is little potential for signal interference.
