The whole reason for using a load cell & torque sensor is to be able to weigh your loads effectively and accurately, so when they are not giving us the accuracy that we expect, it leaves us wondering just what is affecting the accuracy of our equipment. Well, there are a number of reasons as to why your load cell & torque sensors are not providing the top level of accuracy that you would expect, with each of them being listed here.

The Precision in the Load Cell & Torque Sensors – The first thing you should be doing when you are chasing accurate weighing accuracy is always to select a top quality multi axis load cell manufacturer. While all manufacturers will proclaim that their products offer high amounts of accuracy, merely the top brands will most likely have the capacity to deliver the best accuracy.

An excellent load cell and its torque sensors will generally have good response times (how fast they give an exact reading), will never respond to much to temperature changes in the surroundings, is not going to suffer with creep (a modification of the reading after 2-3 minutes of being stationary), and can have suprisingly low ‘nonrepeatability’ (variations in the readings for the same load after repeated loadings).

Factors with all the Load – The accuracy of a load cell & indicator reading may be affected by how the load is put on the weighing system. To make sure an accurate reading, the stress has to be put on each cell properly so when specified by the manufacturer.

If a load has been applied poorly, like the load being twisted, the cell and weighing system will only throw up inaccurate results. To ensure complete accuracy when weighing, the burden must be placed in such a way which can be supporting all the weight proportionally.

Outside Forces – One more reason why accuracy could be affected on torque transducer is the many outside forces that may be slightly altering the load force. Wind, shock loading, vibration, and changes in temperature can all have an effect on the true accuracy of any reading.

A cross-wind can have an effect that the load feels lighter than it actually is while shock is the method of putting on more load weight compared to what the body weight capacity in the cells are. Vibrations using their company nearby machines dzrgzs also cause fluctuations in a weight whilst temperature alterations in environmental surroundings could cause materials inside the load either to expand or contract.

Signal Interference – The last method by which the precision of the weight of any load could be affected is through interference using the signal transmission. The stress cell electrical signal could be suffer with interference from radio frequencies, electromechanical interference, and also moisture inside the air may cause interference for the electrical signal.

Summary – So in order to ensure that compression load cell are as accurate as is possible; you should be well aware of exactly what could affect that accuracy and place measures in place to prevent those occurrences from happening. Just use the best manufacturers of load cells & torque sensors leading brands, load them correctly, make certain that outside forces are limited, and this there is very little probability of signal interference.
