Introduction For the safety of people, goods and elevators themselves, the national standard GB7588 \"Safety Code for Elevator Manufacturing and Installation\" has set strict requirements to prevent elevators from overloading. In addition to the effective area requirements of the car, Article 14.2.5 stipulates that when the car is overloaded, a device on the elevator should prevent the elevator from starting normally and re-leveling; overload means exceeding 10% of the rated load and at least 75kg. In addition, some control functions of the elevator, such as full-load direct driving and anti-tampering functions, also require a device to measure the elevator load to provide the control system with the elevator load signal. The elevator control system generally requires the measuring device to provide three switch signals of light load, full load and overload. Alpha elevator weighing sensor is specially designed for measuring the load of the elevator using special technology, which can provide load switch signals for the elevator control system; and the performance is stable and reliable, with high precision and strong versatility (can be used for elevators with various rated loads), and it is cost-effective and suitable for elevators with various loads.
