Elevator load sensors, integral to safety and operational integrity, serve as pivotal weigh stations monitoring the dynamic payload within the elevator car to avert overloading hazards. Operating on the fundamental principle of strain gauge technology, these devices undergo a measurable change in resistance when the sensing element deforms under applied load. Upon ingress of passengers or freight, the load is transferred to the sensor, inducing a deformation proportional to the exerted force. This deformation precipitates a variation in electrical resistance, which is then transduced into an analog or digital signal by the sensor's sophisticated circuitry.
The resultant signal is meticulously analyzed by the elevator's advanced control system, endowed with the capability to ascertain if the cumulative weight surpasses the predetermined safety threshold. Upon identifying an overload condition, the system promptly initiates a safety protocol, inhibiting door closure and elevator motion, thereby compelling passengers to alleviate the excess load.
