| 1. The actual usage accuracy has exceeded 0.2% and can be maintained for a long time; |
| 2. The fully suspended weighing frame greatly simplifies the structure and provides better stability; |
| 3. Due to the use of a direct load-bearing weighing frame, there are no lever fulcrums, no movable parts, and no issues such as fulcrum wear and rubber aging; |
| 4. The horizontal surface is small, with less dust accumulation, and does not require frequent cleaning. Daily use can basically avoid maintenance trouble; |
| 5. It is composed of 2-8 sets of four roller fully suspended weighing racks arranged in a simple and independent structure, with a weight reduction of 20%, greatly weakening the error impact caused by the mechanical structure of the weighing rack; |
| 6. Adopting STC products from Shiquan Company in the United States, with good stability, lateral force resistance, sealing, temperature compensation, and overload protection functions, higher sensitivity, fully ensuring detection accuracy; |
| 7. The pioneering instrument is equipped with a built-in temperature sensor, which can detect real-time changes in the on-site environment temperature and incorporate it into the instrument algorithm. It can also compensate and correct changes in parameters such as the zero point and sensitivity coefficient of the weighing sensor; |
| 8. Using on-site digital converters, analog-to-digital conversion is carried out on the scale frame to digitize and transmit signals remotely, ensuring high accuracy of signal transmission; |
| 9. Real time monitoring of abnormal weighing sensors, timely switching of faulty weighing sensors in case of emergencies, to ensure normal operation; |
| 10. Real time monitoring of belt status changes, continuous tracking and compensation of belt tension impact, and maintaining a long-term accuracy of 0.2% for belt scales; |
| 11. The double roller design structure detects the true rotation speed of the roller, ensuring sufficient width and weight to prevent the belt from jumping. The DC pulse generator does not require adjustment or replacement of carbon brushes, resulting in a longer service life. |

| 1 | Measurement function | a. Instantaneous flow calculation b. Accumulated traffic c: Belt speed measurement |
| 2 | Monitoring function | Monitor the opening and closing status of the casing, remote reading of measuring instrument parameters, power supply status of the measuring instrument, abnormal coal conveying status, abnormal metering status, on/off status and time of the coal conveying equipment, abnormal communication status, abnormal sensor status, conveyor operation time, hourly output, and upload them to the upper computer, etc. |
| 3 | Storage function | The storage of communication, sensor load and other parameters, as well as the storage of default parameter settings, will not be lost when powered off. |
| 4 | Port function | a: The instrument motherboard provides four digital input ports to receive several contact switch signals. This includes the start stop signal of the coal conveyor and conveyor equipment, the opening and closing signal of the casing, and the 485 signal. Provide an analog input port, which is the PID current input signal. b: And provide 4 programmable output ports, 24-240VDC (or VAC) collector open circuit output. Can directly drive control relays. |
| 5 | Communication function | The communication method uses RS-485 serial interface to communicate with the upper computer. Can remotely read and set various parameters of the measuring instrument. |
| 6 | man-machine interface | a: Industrial LCD displays real-time display of accumulated quantity, instantaneous flow rate, belt speed, alarm and other information. b: The 4 * 6 matrix keyboard, combined with a LCD display, enables the setting of various parameters of measuring instruments and other operational functions. |
