Digital electronic truck scale


Digital electronic truck scale is composed of digital weighing sensor, digital weighing display and modular platform. Digital technology has improved the quality of the electronic truck scale, making it easier to debug, safer to use, simpler to maintain, more convenient to communicate, more intelligent, and more anti-interference.


characteristic:


1. Digital communication technology


① RS485 bus technology is adopted to realize the long-distance transmission of signals, and the transmission distance is not less than 1000 meters;


② The output digital signal amplitude reaches 3~4V, which strengthens the anti-interference ability and improves the lightning protection ability of the system;


③ The bus structure is convenient for the application of multiple weighing sensors. A maximum of 32 weighing sensors can be connected in the same system.


2. Intelligent technology


① Prevent using simple circuit to change the weighing signal and size;


② The sensor characteristic parameters can be changed according to the command.


③ The memory capability eliminates the calibration problem after replacing the sensor.


3. Digital calibration technology


① Make the calibration of the weighing instrument bias load (four corners) complete automatically at one time;


② Calibrate the scale range at one time;


③ The scale factor and zero value, and the factor and zero parameter of each sensor can be modified as needed.


4. Fault diagnosis technology


① It has the ability to diagnose the change of zero value of the scale;


② Have the ability to diagnose the change of zero value of each sensor;


③ Have the ability to diagnose the communication changes of each sensor;


④ It has the prompt ability to judge the discrepancy between the address and the number after replacing the sensor;


⑤ It has the ability to prompt various operation error messages.


5. Eliminate cheating


The digital signal is protected by password in the transmission process, which prevents the truck scale from being remotely controlled by illegal elements and prevents cheating.

Installation features of digital electronic truck scale





No foundation pit:


It has convenient drainage, good waterproof performance, convenient maintenance and overhaul, but it covers a large area.


Shallow foundation pit:


The floor area is small, beautiful and tidy, but the drainage design needs to be added.
