Reason for no weight display or reduction during operation of electronic belt scale

　　If there is no net weight during the operation of an electronic belt scale, the first thing to observe is whether the speed indicator on the instrument is zero. The manufacturer of the electronic belt scale indicates that there are generally three lines on the instrument of the belt scale. The first line is the cumulative net weight, the second line is the instantaneous flow rate, and the third line is the speed. If the speed is zero, it is generally a problem with the speed sensor, but it is not necessarily because the speed sensor is broken, Due to the looseness and damage in the area where the speed sensor is connected to the barrel due to long-term high-speed operation, it is clear to open the speed limit sensor housing for inspection. If the connection organization is normal, then the speed limit sensor needs to be replaced。

If the speed is normal, check if the AD value displayed on the instrument is normal. If the AD value is 0 or 65534, it indicates that the load cell is damaged. Check the load cell and replace it if it is damaged.

During the operation of a belt scale, there may sometimes be a phenomenon where the net weight of the belt decreases continuously. The electronic belt scale manufacturer says that the reason for this situation is usually due to the incorrect zero setting of the belt scale or damage to the weighing sensor. Therefore, how to find the fault phenomenon and solve the problem? Generally, we follow the principle of simplicity before complexity to handle the problem.

Firstly, you can perform zero point correction while the belt is idling, and try to perform it twice as much as possible. Finally, we will check whether the total net weight still decreases or keeps decreasing. If it sometimes decreases and sometimes increases, but the quantity remains the same, then there is no problem. If it still decreases, we need to separate the sensor and use the millivolt scale sensor of a multimeter to export it independently. Generally, the correct output of the sensor is 0-20mv, If it is not in this category or exported to zero, it can be determined that the sensor is faulty. Simply replace the sensor.

Through the above two methods, fault detection is basically possible. If it has not been cleared yet, you can consult our company's professional personnel, and we can provide you with a free explanation.
