The digital platform is installed and debugged ; as mentioned above, the digital weighbridge uses a digital sensor, and the sensor generally outputs a digital signal of RS485 mode. Therefore, the digital weighing instrument can be used when forming the weighbridge. The computer can be directly used with special software. There are no major differences in the installation and commissioning of the two configurations. For the convenience of description, the following describes the digital instrument as an example.
Common fault phenomena and troubleshooting methods for weighbridge
1. The floor scale meter shows the reason and treatment of not returning to zero or zero point instability.
The weighbridge often encounters the phenomenon that the meter does not return to zero or the zero position is unstable during use. The meter display does not return to zero means that the zero value is not displayed within the specified time (such as 10 seconds) after power on or after unloading. The zero position is unstable, which means that the instrument displays a jump value such as a negative value, zero value, 1 division value or 2 division values ​​in a certain time range. These two fault phenomena do not affect the weighing process, but will affect the accuracy of the weighing value, so it cannot be ignored. There are four reasons for this failure phenomenon and the elimination methods:
1.1 Due to wind power. Some floor scales are only considered for favorable drainage factors. The scale body will be installed 20cm--60cm above the ground. When the floor-mounted truck scale without foundation pits is windy, the wind will exert its force from different directions. When the wind direction is hung from the bottom of the scale body, buoyancy will occur, and the display will have a negative value; when the wind direction is hung from the side of the scale body, there will be zero value, 1 division value or 2 division values. Therefore, when using the truck scale in a region with a large wind force, it is generally preferred to install the ground balance in the foundation pit, and to properly arrange the drainage and impurity removal position and effectively eliminate the cause of non-return to zero or zero instability caused by the wind.
1.2 Foundation deformation or foundation sinking. When installing the truck scale, the concrete layer thickness of the foundation is generally 40cm--60cm. In the soft soil layer, the steel mesh hardening foundation should be added to the concrete. The base hardening date is not less than 15 days. If necessary, the cement condensation should be prolonged. time. Only when the foundation foundation is hardened can it effectively prevent the deformation of the foundation or the sinking of the foundation to show zero or zero instability.
