Truck scales are also commonly referred to as floor scales, and their use is primarily based on load cells. This shows that the load cell is a heart component in the truck scale, so the selection of weight sensors and fault detection are crucial.
When using multiple load cells as a weighing system, it must be considered what kind of working method it uses. The determination of the working mode must be related to the selection of the weighing instrument, ie the relevant technical parameters of the weighing sensor must match the relevant technical parameters of the instrument. Take the currently used parallel working mode weighing system as an example, it requires that the actual maximum current of the system must be less than the maximum bridge current of the weighing instrument.
Weighing instruments are generally composed of analog circuits and digital circuits. Analog circuits include power supplies, preamplifiers, filters, A/D conversions, etc. Digital circuits include host processors, coprocessors, various memories, keyboards, and displays.
The easiest and most effective method for instrument fault diagnosis is to use alternative methods. First use the simulator or judge the instrument is damaged according to the fault. If you suspect that there is a problem with the PCB, you can use a good PCB board instead. After replacement, use the simulator to check or observe if the fault disappears. After replacing the PCB, the relevant parameters must be set and calibrated according to the instructions. When using a weighing instrument, it must be clear how it connects to the human screen, printer, and weighing software to see if they match the weighing instrument.
The choice and fault detection of weighing scales for truck scales is a key part of the work process. Only when a good weighing instrument is selected and it is guaranteed that it can operate normally, the truck scale can achieve the correct weighing effect.
