● Main Features：
1.The system is of the structure of sensor with the domination of loading cell and controller, which
can be installed at the car-side rope hitch；
2.Directly outputting full-load or overload signal depending on the change of elevator car payload
；
3. Simple adjustment, high precision of measurement and quick and easy installation.
