Factors THAT MAY BE Affecting the Accuracy of Your Load Cell & Torque Sensors

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

The Accuracy of the strain 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 most notable 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 provide an accurate reading), won’t respond to much to temperature changes in the environment, will not suffer with creep (a 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 a load cell & indicator reading could be affected by the way the load is placed on the weighing system. To ensure an accurate reading, the strain has to be applied to each cell properly so when specified by the manufacturer.

If a load has been applied poorly, such as 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 load has to be put into such a way which are supporting all the weight proportionally.

Outside Forces

Another reason as to why accuracy may be affected on lots cell & torque sensor is the many outside forces that could be slightly altering the weight force. Wind, shock loading, vibration, and changes in temperature can all impact the true accuracy of a reading.

A cross-wind can have an impact that the load feels lighter than it actually 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 can also cause fluctuations in a weight whilst temperature changes in the environment can cause materials in the strain to either expand or contract.

Signal Interference

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

Summary

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 in place to prevent 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 potential for signal interference.
