Predictive failure analysis reduces downtime

A broken or damaged load cell can be impossible to detect or predict. Only once batches start appearing out of specification, or the weighing results appear unstable, do users realise that there might be a problem and call out a service technician to identify and repair or replace the broken load cell. This can result in lost production time and disappointed customers.

When a weighing system is no longer weighing accurately, it is usually due to mechanical influences on the weighing structure or load cell deficiencies. In any case, the effects of these influences create several out of tolerance conditions such as: load cell zero drift, load cell over range and asymmetrical load distribution.

This is where TraxEMT can help. With its predictive failure analysis and run flat system failure recovery embedded technology, productivity and product quality need not suffer.

TraxEMT, combined with the RAAD Box/MTX technology, allows continuous individual cell diagnostics and automatic alerts for scale/cell errors via email, SMS as well as on screen prompts. It also features calibration expiration management and scale calibration verification.

This helps users to save time and costs by eliminating long hours of troubleshooting in a multiple cell system and having full control of maintenance schedules.

In the event of a specific cell failure, the TraxEMT and the Run Flat algorithm can take control to allow the weighing process to continue within user-acceptable tolerances.

The embedded run flat algorithm compensates for the failed cell’s erroneous readings until the cell can be physically replaced or fixed. Run Flat performance is typically dependent on the:

Users now have the option to reduce costly batch-in-process wastage and prevent operational downtime.
