The disadvantages of electronic truck scale can be basically divided into two types: common disadvantages and extraordinary disadvantages. However, no matter what kind of shortcomings, they are caused by several primary aspects, such as weighing flash, electronic weighbridge price weighing sensor, power supply, connection line and mechanical transmission arrangement. Its disadvantages are caused by unreasonable equipment plan or improper use and natural damage.
However, some special shortcomings of the electronic truck scale are rarely seen in ordinary times. For example, the inherent defects of electronic automobile weighing elements are not easy to deal with. If the production process of electronic weighbridge can be recognized in time, it can reduce unnecessary losses.
For example, when the equipment was calibrated with inspection weights, it was found that the weight flashed on the surface was not changed according to the weight of the weight applied, but was increased and decreased, and the number of flashes on the surface was also related to the placement direction of the weights, so normal calibration could not be carried out.
The connection method of the weighing sensor of the electronic truck scale is parallel connection, and the connection circuit of the sensor is accurate (the sensor is connected according to the color code of the wiring diagram in the manual. Electronic weighbridge material The flash surface and some machines have no disadvantages. After careful analysis of the above phenomena, it can be distinguished that today's sensors are in doubt.
Calibrate the flashing surface with the simulator, then connect it to the sensor, and then use a weight to weigh the four corners of the scale, Electronic weighbridge manufacturer The effect is that three corner flash values are positive, while the other corner flash value is negative. Therefore, it can be concluded that the internal wiring of the sensor at this angle is wrong. After the bridge voltage of the sensor or the positive and negative leads of the signal line are exchanged, the angle also flashes to a positive value.
From this view, it can be distinguished that the sensor of the weighbridge has reversed the positive and negative poles of the bridge voltage or signal internal leads when it was packaged before leaving the factory, so the above shortcomings occur when the device is connected according to the normal color code.
