Weighbridge, also known as electronic truck scale, is widely used in various industries, such as port, wharf, airport, mine, metallurgy, materials, warehouse and the weighing and measurement of heavy cargo vehicles of factories and enterprises.
However, in the long-term use of the weighbridge, it is inevitable that various problems will occur due to improper operation. If the weighbridge fails to repair in time, it is likely to bring a lot of economic losses. For example, when the weighbridge is used in a negative situation, you may be at a loss. So what is the problem? Next, let Jiangmen Electronic weighbridge manufacturer Lidong Weighing Instrument will give you a detailed explanation.
The situation that results in a negative number in the weighing process of the weighbridge is as follows:,
1、 Check the internal circuit of the weighbridge to see whether the voltage and current of each part are normal operating conditions;
2、 Sensor of electronic weighbridge. The sensor of electronic weighbridge is planned to be a pressure elastic structure. After weighing the object, it may lead to a negative number until the elastic body returns;
3、 It may also be the internal limit of the electronic weighbridge.
How to solve the problem after finding negative numbers in the use of the weighbridge? First, check whether the circuits, sensors and limits of the electronic weighbridge have changed. It is mainly to open the main line and junction box for a look. In addition, it is recommended to remove the things under the weighbridge. If the limit of the weighbridge is in doubt, loosen the limiter first. Secondly, when the electronic weighbridge is weighed, the negative number must be cleared by pressing the key in time! Otherwise, the weight after weighing will be less than the practical weight.
Generally, there are two kinds of zeroing. Normal reset, for example, - 40KG occurs because the sensor elastomer is not completely reset; At this time, clearing is normal clearing, so that the instrument can keep zero again. Illegal zeroing, for example, there is a vehicle or heavy object weighing on the electronic weighbridge. If the reset key is pressed, then when the vehicle or heavy object is weighed down, a negative number appears on the instrument. This negative number is a malicious operation, and you should press reset to zero again.
Jiangmen electronic weighbridge manufacturer reminds that if the negative difference is particularly large, it should be considered that the parts or circuit of the weighbridge are faulty.
