How to enhance the weighing accuracy of electronic belt scales

Electronic belt scale, also known as "electronic belt scale", is an accurate measurement and verification system that continuously measures and verifies bulk materials on belt conveyors. The equipment components of the electronic belt scale determine its weighing The following methods can enhance the weighing accuracy of electronic belt scales.

1. Weight sensor

Use a weight sensor with good linear shape and add pre-pressure to make the sensor work in the linear area.

2. Speed ​​sensor

The speed sensor uses a sensor without boundary effects. Photoelectric sensors are better and can avoid interference.

3. Scale frame

The scale frame of the electronic belt scale should be as long as possible, stable in the weighing section, and the force transmission is linear. It should be calibrated as much as possible during assembly and should be cleaned frequently during use to prevent dust collection from interfering with the tare weight change.

4, roller

Try to use rollers with flexible rotation and small vibration, and each set of rollers should be as uniform as possible.

5. Transmission belt

The thickness and width of the belt of the electronic belt scale should be as uniform as possible, and the connectors should not be made of metal as much as possible to reduce the change in tare weight.

6. Data signal route

The data signal lines of the electronic belt scale weight sensor and speed sensor should use shielded twisted pairs to reduce interference.

The electronic belt scale instrument should use an instrument panel with LED display or Ruixing display. It is considered that the LCD display is not very bright and does not work well when the temperature is too low.

The accuracy of the electronic belt scale has nothing to do with the display chosen for the secondary instrument. It can be said that the LCD display is the future development trend, but is related to the actual A\/D digits of the instrument panel, from 8 digits in the early days to now. 24-bit, the accuracy of the instrument panel has been greatly enhanced, and can guarantee an accuracy of 0.01%. Nowadays, the global power supply (80265) wide power supply is used internationally, which is probably not possible in China at this stage.
