Digital weighbridge adopts digital communication, and the biggest advantage of digital communication is to solve the problems of poor transmission signal and anti-interference. The maximum output signal of analog sensors is generally tens of millivolts, which is easily disturbed during the cable transmission of these weak signals, resulting in unstable system operation or reduced measurement accuracy. However, the output signals of digital sensors are all around 3-4V, and the anti-interference ability is hundreds of times greater than that of analog signals, which solves the problem of weak and interference transmission signals.
Extended data:
In general, the commonly used scales in the construction site are 3*9m, 3* 10m, 3* 12m, 3* 14m, 3* 16m and 3* 18m. For example, if the car is the first four and the last eight models, you can choose a 3*9m weighbridge; If the weighing vehicle is a semi-trailer, you can choose 3* 16m weighbridge, and so on.
The same is true for tonnage selection. Commonly used tonnages are 50t, 60t, 80t, 100t, 120t, 150t. At present, the maximum T-bit demand of the whole weighbridge generally does not exceed 150t. Generally speaking, the size and T-bit can be determined according to the needs of customers.
