U-Shaped Steel Structure Digital Truck Scales
In the field of electronic weighing, with the development of electronic measurement technology and microelectronic technology, electronic weighing technology has also realized the transition from analog weighing to digital weighing, which represents the development trend of electronic weighing technology. Digital truck scales using digital weighing technology are undoubtedly the more advanced electronic truck scales.
● High accuracy: Digital weighing instruments directly process digital signals, eliminating the shortcomings of analog weighing instruments in "sensitive areas". The instrument's anti-interference and field adaptability have been greatly improved, and its high-precision measurement capabilities have been greatly enhanced. The realization of a weighing system with measuring accuracy offers the possibility.
● Strong anti-interference ability: Because the A / D conversion is completed directly inside the sensor, the sensor directly outputs digital signals, which overcomes the shortcomings of susceptible to interference in the transmission of tiny analog signals of previous analog sensors, enhances the anti-interference ability of the system, and improves the signal resolution and stability Sex.
● Intelligent: Digital truck scale instruments are more concise, convenient and user-friendly in terms of fault detection, on-site accurate determination of faulty sensors, automatic digital angle correction during installation, digital linear correction, and independent sensor measurement detection.
● Strong measurement adaptability: Digital instruments have lower requirements for the use environment and sensor sensitivity of truck scales than analog truck scales, and the range of signal processing is larger than that of analog truck scales.
● Prevent cheating: The transmission and processing of pure digital signals eliminates the possibility of current measurement cheating by changing analog signals, and enhances the weighing safety and true accuracy of truck scales.
Body Characteristics of Truck Scale

Advantages of steel structure truck scale products:
The introduction of large-scale "large robot automatic welding", "large automatic pre-arch machine", "NC bending machine", "NC shearing machine", "NC laser cutting machine" and other special equipment, the main beam of the scale body is folded by special equipment Bent into a U-shaped beam. U-shaped steel structure scale body is by far the most reasonable electronic truck scale body structure in China. The U-shaped steel load-bearing main beam is cut according to the length without joints, and has higher welding strength than ordinary steel main beams with joints. The U-shaped steel support platform has a distance of 1/2 smaller than that of ordinary steel, which is close to the width of automobile tires. it is good.
