When overload buzzers cry wolf, technicians eventually bypass them. That is how a neglected elevator load weighing device becomes a safety problem.

Crosshead/rope load cells, underfloor sensors, or simpler switches — each needs the right empty and loaded references. Recalibrate after rope work, major cabin changes, or as part of annual inspection. Freight cars especially need trustworthy overload detection.

Keep the sensor model on the spare list. A generic substitute that “almost” fits will drift again in a month.

RITECH integrates weighing on passenger and freight platforms. If your fleet alarms randomly, start with calibration and wiring before you replace the controller.
