The whole point of experiencing a load cell & torque sensor is to be in a position to weigh your loads sufficiently and accurately, so when they’re not giving us the accuracy that we expect, it leaves us wondering just 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 aren’t providing the high level of accuracy that you’ll expect, with all of them being listed below.

The Accuracy of the Load Cell & Torque Sensors

The very first thing you should 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 levels of accuracy, only the top brands will usually manage to deliver the best accuracy.

A good load cell and its own torque sensors will generally have good response times (how quickly they give an accurate reading), will not react to much to temperature changes in the environment, will not suffer with creep (a big change in the reading after 2-3 minutes of being stationary), and will have suprisingly low ‘nonrepeatability’ (differences in the readings for exactly the same load after repeated loadings).

Factors with the Load

The accuracy of lots cell & indicator reading could be affected by the way the load is positioned on the weighing system. To ensure an accurate reading, the strain has to be put on each cell properly and as specified by the manufacturer.

If Loadcell has been applied poorly, like the load being twisted, the cell and weighing system is only going to 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 the reasons 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 effect that the load feels lighter than it really is while shock is the process of gaining more load weight than what the weight capacity of the cells are. Vibrations from other nearby machines may also cause fluctuations in a weight whilst temperature changes in the surroundings can cause materials in the load to either expand or contract.

Signal Interference

The final way in which the accuracy of the weight of a load could possibly be affected is through interference with the signal transmission. The strain 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 possible; you should be well alert to precisely what could affect that accuracy and put measures set up 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.
