Elevator Weighing Sensor Device with Signal Acquisition Load Judgment and Torque Compensation for Enhanced Safety and Comfort

Elevator Weighing Sensor Device, Elevator Load Sensor, Photometer, Elevator Accessories LS BOARD HLC-2004 LOAD-CP

Signal Acquisition and Processing: Receives analog signals from the car bottom weighing sensor (e.g., strain gauge type), amplifies, filters, and converts them into digital load values ​​via A/D conversion.

Supports parallel input of multiple sensors, using algorithms to eliminate off-center load errors and improve weighing accuracy.

Load Judgment and Safety Control: Presets full load (95% rated load) and overload (110% rated load) thresholds, triggering corresponding protection logic: In case of overload, the elevator is prohibited from starting, a buzzer alarm is sounded, and a fault is displayed; In case of full load, it automatically switches to "direct drive mode," prioritizing responses to commands from inside the car to improve operating efficiency.

Torque Compensation and Comfort Optimization: Outputs load compensation signals to the main control system, driving the frequency converter to adjust the motor torque, offsetting the difference between the car's weight and load, achieving smooth starting/braking and preventing slippage.

Supports dynamic load monitoring, adjusting compensation in real time to improve ride comfort.

System Compatibility and Maintenance Convenience: Compatible with Hyundai STVF5/STVF7 series elevators, communicating with the main control board (such as H21/H23) via CAN bus.

Built-in self-diagnostic function, supports parameter calibration and fault code output, facilitating quick troubleshooting by maintenance personnel.
