Elevator load sensors, or weigh stations, play a critical role in elevator safety and functionality. Their primary function is to monitor the weight inside the elevator car to prevent overloading, which could lead to accidents or equipment failure. These sensors typically operate on the principle of strain gauges, where a change in resistance occurs when the sensor element deforms under load. When passengers or cargo enter the elevator, the weight is transmitted to the load sensor, causing a deformation that is proportional to the applied force. This deformation results in a change in electrical resistance, which is then converted into an electrical signal by the sensor's circuitry.

The output signal is processed by the elevator's control system, which can determine if the weight exceeds the safe limit. Upon detecting an overload, the system prevents the doors from closing and the elevator from moving, signaling the passengers to remove excess weight. This mechanism not only ensures passenger safety but also prolongs the life of the elevator machinery by preventing strain beyond its design capacity. In modern elevators, digital sensors offer increased accuracy and reliability, contributing to a safer and more efficient vertical transportation experience. Elevator load sensors are indispensable for maintaining safety standards and regulatory compliance in building management.
