Q: What kind of maintenance will keep my weighing equipment accurate?
A: Alan Homan, Schenck AccuRate, says:
The first thing you must remember—and the most often forgotten—is that you're working with a scale. Whether it's a hopper on load cells for weight indication or a screw feeder operating in a traditional gravimetric feeding mode, it's still a scale-based system.
Everything that's connected to the scale will affect how accurately it performs. During the initial installation, it's important that all process connections to the scale are flexible, that the electronic component wiring isn't rigid, and that the scale's mechanical components are properly vented. Over the scale’s life, these items should be checked and maintained on a regular schedule.
Additionally, you should perform periodic system accuracy checks using your weighing electronics' tare, span, and linearity functions. Finally, it's important to work with weighing companies that provide qualified technicians to work with you on the installation, start-up commissioning, operator training, and routine preventive maintenance.
