Description:
First, the structure of the export type truck scale
1, all steel structure modular weighing platform: steel structure, low platform, no bridge, modular. U-shaped main beam, split in the middle, bolted connection, easy to install and disassemble, convenient installation. Suitable for 20 feet, 40 feet, high container or open top container transportation
2, high-precision resistance strain gauge sensor: with high precision, long-term stability and wide working range, good self-positioning performance, automatic removal of various side forces.
3, using ultra-low drift, low noise, fast and high-precision Delta-σ A/D converter, conversion speed > 500 times/second, the number of degrees 1 million. MCS-51 single chip microprocessor, large six-bit fluorescent weighing value display and 16-point matrix LCD function display, with uninterrupted clock circuit, standard Rs 232c, Rs 422 asynchronous serial interface, can communicate with the computer, can be connected to the large screen display, connected to the printer can be Chinese recording statistical printing: Four bills, class, combined class, daily newspaper, car number, article number, etc.; It has strong software functions: dynamic/static weighing switch, gross/net weight display conversion, date/time modification and display, vehicle number/item number setting and display, number/cumulative display, index value selection, peeling, tare weight typing, zero setting, automatic/manual switching, weighing calibration, parameter setting and modification, shift exchange, storage, storage data lookup, clearing and so on
