The hopper scale is an important tool for quickly, intuitively, and accurately displaying trade measurements in warehouses and freight stations. As a tool for trade settlement, the reliability, accuracy, and scientificity of hopper scales have a crucial impact. In the exchange of goods, the weighbridge serves as a bridge for equal exchange. Once the weighbridge appears to be out of line with practical values, it can lead to unequal buying and selling, which can be detrimental to the smooth progress of work, or even cause economic losses to consumers.

Below, the hopper scale manufacturer will teach you a few tips on how to identify the reasons for inaccurate hopper scales, and how to quickly repair the hopper scale after encountering related problems.

1. Instrument display failure

(1) Fault Cause Analysis

The abnormal instrument display of the hopper scale during use is mainly caused by the following four reasons:

① The instrument itself is malfunctioning

② The wiring between the connecting instrument and the junction box is loose, resulting in poor circuit contact

③ The wiring board of the hopper scale is affected by moisture, which affects signal transmission

④ Damaged weighing device

(2) Fault handling measures

Use the simulator to connect the display instrument and check whether the instrument display is normal? Are there any signs of looseness or damage in the connecting wires between the junction box and the instrument? If any looseness is found in the connecting wire, it should be immediately plugged in tightly; If there is damage, a new connecting wire should be replaced in a timely manner. At the same time, the wiring board of the weighing scale should be checked for moisture, and ventilation and drying measures should be taken for the wiring board. A comprehensive and detailed inspection of the weighing sensor should be carried out to promptly eliminate any faults that may occur in the application of the weighing scale.

2. The display problem of the electronic instrument panel during electronic weighing

(1) Fault Cause Analysis

The factors that cause problems with the display of electronic instruments during electronic weighing are manifested in many aspects, one of which is very prominent, which is the problem of damage to the original components between the connecting parts of electronic weighing instruments, resulting in unstable and even biased signal transmission between instruments.

(2) Fault handling measures

Control the issue of damage between the connecting components of electronic weighing instruments, eliminate faults, ensure the long-term normal working status of the instrument panel, conduct detailed troubleshooting work on the equipment that has caused the problem, and promptly repair and replace the damaged connecting equipment as soon as possible.

3. Zero obstacle of instrument after machine restart

(1) Fault Cause Analysis

In the usage methods of machine instruments used in various disciplines, resetting the instrument to zero after restarting the instrument is a potential rule for instrument use, and load cells are no exception. Moreover, load cells are more prone to serious zero drift problems, and non zero displays on the instrument panel often occur. The elimination of certain tasks is gradually receiving attention.

(2) Fault handling measures

Strict testing and inspection of the relevant components and equipment of the weighing sensor are required, timely and effective troubleshooting work is carried out, and the faulty parts are replaced in a timely manner to ensure their normal use.

Selection of hopper scales: It is recommended that colleagues who purchase hopper scales must choose manufacturers with excellent quality and configure suitable hopper scales according to our actual usage needs. For example, choosing waterproof and anti-corrosion hopper scales can avoid many unnecessary problems.
