1. Complete vehicle scales | Specially designed platform with additional axle identification |
2. Weighing Controller | This is the brain of the system, made up of several microprocessors, responsible for processing the information of the platform, the axle recogniser (if configured), the vehicle separator, sending the weighing data to the computer, and sending the control signals to the electric barriers (if any) |
3. Wheel and axle recogniser | It is used to identify whether the passing axle is single or double wheel, whether it is configured or not is decided by the system demand |
4. Vehicle separator | It is used to indicate whether the vehicle is completely on the platform, usually using infrared light curtains, or ground sensing coils or similar equipment can also be used |
1. Adopt 20BIT ∑-△ type A/D converter, linearity 0.0015%; |
2. Support 8 350OΩ sensors; |
3.1600 times weighing result storage (expandable to 3500 times); |
4. Built-in 7000 Chinese characters font, you can input the Chinese name of user unit, customer unit and weighed goods on the spot; |
5. Very complete summary and statistical functions; |
6. Supports 9-pin and 24-pin printers, multiple print formats; |
7. excellent consistency, no need to recalibrate the instrument when replacing it; |
8. Extremely simple commissioning and operation; |
9. Very high dynamic accuracy; |
10. Support shaft metering and whole car metering, dynamic and static compatibility; |
11. Mainly used in dynamic shaft metering, dynamic vehicle weighing, and can also be used in other special purpose scales that require dynamic weighing; |
12. RS232 computer communication interface. |
