What happens if a load cell is damaged during production? The process may be shut down, material may be wasted and costs may increase. The TraxEMT software detects failure in an early stage or enables the process to continue despite a failure.

What happens if a damaged load cell is detected during production? Is the process shut down?,Is material wasted? Are costs increased? Or, even worse, what happens if a damaged load cell has not been detected?

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 appears unstable do you get an idea that there might be a problem. Then you need to 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.
This is where TraxEMT™ can help. With its predictive failure analysis and Run Flat system failure recovery embedded technology your productivity and product quality will not suffer.

Predictive failure analysis
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
* Asymmetrical load distribution

TraxEMT™ combined with the RAAD Box™ / MTX® technology allows:
* Continuous individual cell diagnostics
* Automatic alerts for scale/cell errors via email and on screen prompts
* Calibration expiration management
* Scale calibration verification
This helps you to save time and costs by eliminating long hours of troubleshooting in a multiple cell system and having full control of maintenance schedules.

System failure recovery
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*.

“Run Flat saved my day”.
“While we were adding component three we were alarmed that one of the four weigh modules of our stirred reactor had failed. We found later that it had been hit accidentally by a pallet truck that same day. We immediately triggered the Run Flat function and could finish and save our batch.”

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:
* Configuration (e.g., number of cells) and structure of the scale
* Substance weighed
* Loading pattern

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