"Digital truck scale" represents the most advanced technical level of electronic truck scale. It uses advanced digital intelligent weighing sensor and digital weighing display instrument to make the overall performance of the truck scale better and the environmental adaptability stronger. The degree of heavy intelligence is higher, which greatly improves the high-tech quality of the electronic truck scale.

Features
To solve the eccentric load error, the adjustment of the four corners is more convenient: the digital truck scale can automatically compensate and adjust the influence caused by the eccentric load and temperature changes, which has changed the manual adjustment of resistance in the past, and the computer can encode and encode the digital signals output by each sensor. Identify, use software to automatically adjust the angle difference, making the error adjustment simpler and more accurate.
With fault self-diagnosis ability: The digital truck scale has an advanced man-machine dialogue interface, and the self-diagnosis function is outstanding. It can continuously detect the working condition of the truck scale during use. When a sensor fault is detected, it can send an error signal in time to make an accurate judgment. The point of failure avoids the loss caused by the failure.
Strong anti-interference ability: Most of the electronic components of the digital sensor are installed in the sensor shield, using a highly integrated and highly intelligent processing unit, independent A/D converter and digital signal output port, eliminating the need for long-distance transmission. , the voltage signal is low and susceptible to interference.
Eliminate cheating phenomenon: The digital signal is protected by password during the transmission process, which prevents the truck scale from being remotely controlled by criminals and prevents the appearance of cheating.
The scale platform is equipped with buffer limit devices in both vertical and horizontal directions to prevent the impact force and lateral force generated by vehicle overrunning and braking, so as to protect the weighing instrument.
The weighing platform panel is made of high-quality steel plate with a thickness of 10mm, which ensures sufficient strength and does not deform after long-term use.
The transmission junction box is made of high-quality stainless steel to prevent corrosion.
The transmission cables shall be installed and protected according to the national standard, and the arrangement shall be neat and reasonable.
The information collection of the equipment is stable, accurate and reliable. The printing output is convenient, high speed, low noise, reliable and durable. The design structure of the weighing platform is reasonable, and the overall rigidity is good, which ensures that it will not be deformed in long-term use, and ensures the measurement accuracy of the weighing body.
All surfaces to be painted are thoroughly treated for appearance quality and rust removal before painting. The surface of steel structure is pretreated by sandblasting to meet the requirements of overall wear resistance, pressure resistance, acid resistance, alkali resistance and strong corrosion resistance of the scale body.
The weighing platform is welded with cold-formed U-shaped steel and steel plate to form a stable box girder structure, and steel is selected from well-known domestic iron and steel enterprises.
The quality of the parts material conforms to the standards stipulated in the national regulations.
The surface of the weighbridge is painted with red red fire-resistant and anti-rust paint twice, and the topcoat is painted once.
