Helpful Tips For Selecting The Correct Load Cell Sensor

There are different components in a web tensioning system or any type of weighing system that may fail during operation. Replacing just the failed component can save significantly on the cost of the repair, and ensures limited downtime as opposed to replacing multiple components.

Common Issues

When a load cell sensor fails, there are several symptoms that may be present. Inaccuracies in the measurement may be the first indicator, but this may be difficult to determine unless there is some obvious sudden change in the tensioning across the system. This can occur gradually, which is called creep. As the change is so slight, it is often undetected for a long period of time.

Slow response times, not zeroing when the load is lifted as well as problems in readouts from the sensor can all be additional indicators. If there has been damage to the machine or system, it is a good idea to verify the load cell is still functioning correctly.

Selection Criteria

When buying from a reputable manufacturer, it is not necessary to always choose the same load cell sensor. Top manufacturers design the load cell sensor to be versatile and to integrate with other components from different manufacturers. Ideally, using the same manufacturer for all components of a web tensioning system is the easiest option as everything is designed to operate effectively together without additional modifications or configuration adjustments.

Take the time to consider the parameters of use for the load cell sensor. This includes the application specifications and the amount of load the cell is required to manage. Do not consider the average in isolation, instead keep in mind the upper and lower levels as these are the key points for problems with accuracy if the wrong load cell is used.
