When we use the weighbridge and truck scale, there will always be a certain probability of various problems, and sometimes the sensor may be damaged by us! If the weighbridge sensor can not be used normally, we can first conduct a simple inspection to determine whether the weighbridge sensor is damaged, and we can carry out simple maintenance!
1. First find the damaged sensor, open its cover plate, then use a jack to lift the scale body, and take out the ground wire of the sensor.
2. Open the junction box, remove the sensor and the line connected to the boundary, and connect the cable of the new sensor to the original connector. Find out the pictures in the instruction manual, and fix each circuit on the corresponding position of the junction box according to the schematic diagram above.
3. Slowly withdraw the jack, then cover the outer cover of the sensor and tighten the screws.
4. When the weighbridge sensor is loose, it can be rotated by hand. At this time, the sensor is under little or no force, resulting in unstable zero point of the empty table and inaccurate weighing data. If the spiral lifting structure is used to adjust the height of the sensor, first loosen the spare nut of the sensor base with a hook wrench, and then tighten the sensor with a hook wrench to lock the spare nut to avoid loosening again.
5. When the groove of the pressure head of the weighbridge sensor is too deep, the sensor sensitivity will be affected. When weighing, the instrument will display data slowly after the truck stops stably. The solution is to jack up the weighing beam with a jack and pad it between the sensor and the upper head with a gasket. The solution is to replace a suitable sensor head.
6. If the force on the weighbridge sensor is uneven, it will exceed the tolerance at some point during calibration. In the state of empty scale, judge whether each sensor is evenly stressed by the internal code value displayed by each sensor in the instrument. As the sensor adopts a spiral lifting structure, when the force on the sensor is uneven, the hook wrench can be used to adjust the sensor to make it evenly stressed.
How to repair the broken sensor of the weighbridge and truck scale is just a few of the above. Usually, we should pay attention to the use of the weighbridge and truck scale. Don't use them casually. It is important to develop a good habit of using the weighbridge and truck scale.
