Sensor installation
Product Features:
1. Perfect solution for building hoist/construction elevator's overload protection, with classic plastic shell, the load limiter is easy for installation;
2. High accuracy: Controller's measurement accuracy is better than 1%, which is much better than analog singal indicator;
3. Display: 4 digit display, 00.00-99.99, the limiter can acheive high accuracy weighing results;
4. Wide voltage range: AC110-440V, suitable for 99% of the construction site, which is more suitable than tranditional indicator
5. Single way normally closed contact for power cut-off;
6. Support RS232/485 communications, can be connected with monitor screen or PC.
7. Black box function: the overload limiter can record the data up to 4,000messages of load/overload during operation
8. Easy debugging, just press one button to correct all the weighing date without actual weights;
