Digital weighing module adopts T-BUS bus, the whole sensor on the 2 wires, no polarity arbitrary connection, there is no possibility of connecting the wrong, short-circuit does not damage the equipment, lightning, anti-power, so that the system is simplified to the extreme, the reliability of the system is greatly improved, the installation and maintenance has become extremely simple, to overcome the RS485 chip is very easy to be damaged due to lightning strikes to make the sensor scrapped, for the digital scales into the full-intelligence of foolproof type application. This has laid the technical foundation for the digital scale to enter into the fully intelligent and foolproof application. The two-way transmission of data from the digital weighing module can store the identity information of the load cell (model, range, factory number, sales time, etc.), use information (customer classification code, overloaded weight, overloading times, etc.), etc. inside the load cell, which can be automatically recognized and read out by the instrument to realize the electronic storage of information. Through automatic identification, the instrument can automatically determine the suitability of the connected load cell, making foolproof application possible. Since the range of the load cell can be read out at any time, the weighing instrument can convert its output code into a uniform kg value according to the range of each load cell, realizing the application of mixing load cells with different ranges and soft zero correction. At present, most domestic digital weighing systems have the problem of zero deviation in use, which results in measurement deviation and even scrapping of sensors from time to time, the reason for this is that the zero point of the digital weighing system can not be corrected. The reason is that the zero point of digital weighing system can not be corrected, this weighing system adds software zero point in each sensor, which is used to correct the zero point change caused by temperature drift and creep, and completely solve the problem of zero point deviation of digital weighing sensors in use. Instead of using the standard hardware serial module, the instrument and the load cell are encrypted by customizing special communication protocols to ensure data security and improve the anti-cheating performance of the system.

In summary, the new generation of 2-wire digital weighing module not only simplifies the installation and maintenance of the system, but also overcomes the inherent defects of the conventional digital weighing module, which truly realizes the foolproof application of intelligent products. No training is required to complete the installation and maintenance of digital electronic scales will be the maintenance personnel to liberate, so that digital electronic scales are no longer for the fear of ordinary people, manufacturers worry about the development of electronic scales is of great significance.
