load cell

As we all know, belt scale as a kind of automatic industrial advanced equipment for continuous weighing and dynamic measurement of bulk materials has been favored by many industries such as coal mines and electric power. For its function, we have to admit that the load cell has played a huge role in belt scale .

Due to its continuous work day after day, or improper use of the operator, the belt scale weighing sensor will inevitably appear some failures.

1. itself damaged

For belt weighers, the load cell is its most important and important component. If the load cell is damaged, the device will have unfavorable phenomena such as unstable output signal, obvious hysteresis, and excessive zero drift.

Damage to the load cell results in inaccurate weighing of the material and even in severe cases. At this time, we must consider the timely replacement of the load cell.

2. wrong capacity selection

The load cell works best at full capacity. To maintain the metering requirements and to satisfy the sensitivity, it is difficult for personnel to operate. If the full capacity is selected based on the average amount of belt weighers passing through, it may cause the material to be overloaded when it passes through the belt weigher, and there is sometimes a problem of no load.

Sensor capacity is too small, it is easy to produce cut-top overload; capacity is too large, the sensitivity is not enough, so we must choose a reasonable size.

3.wiring error

Wiring errors are artificial errors that can easily occur. First, the input and output terminals may be connected to each other, resulting in deterioration of the stability. Second, the ground state of the shielded line and the red case is poor.

In addition, the electromagnetic signal interference can not be ignored.
