Sensor installation
Product Features:
1. Operation language can be set as English or Chinese;
2. Standard slot installation, the shell is of ABS fire-resistance material,
3. High accuracy: Controller's measurement accuracy is better than 1%, which is much better than analog singal indicator;
4. Display: 6 digit LCD backlight display, 000.00-999.99, the limiter can acheive high accuracy weighing results;
5. With built-in battery, the overload limiter can work up to 8hours without power, and can recharge itself automatically once the power is on, which ensures the safe operation of the building hoist/construction elevator when the door is open;
6. Wide voltage range: AC110-440V, suitable for 99% of the construction site, which is more suitable than tranditional indicator
7. Dual way normally closed contact for power cut-off;the overload limiter can also be connected to extra buzzer or display;
8. Supportive to RS232/485 communications, can be connected with monitor screen or PC;
9. Supportive to 0-5V, 4-20mA analog output;
10. Easy debugging, just press one button to correct all the weighing date without actual weights;
