The axle load scale is made up of steel structure module scale weighing platform, high precision resistance strain type analog sensor and dynamic weighing control display instrument. The instrument uses ultra-low drift, low noise, high precision DC amplifier, fast and high precision Δ-Σ type A / D converter, conversion speed> 500 times / sec. MCS-51 single-chip microprocessor, a large six fluorescent weighing value display and function status display, with uninterrupted clock circuit, the standard RS 232c, Rs 422 asynchronous serial interface can communicate with the computer can be accessed by large screen display, Connect the printer can be recorded in Chinese statistical printing: four single, classes, classes, daily, car number, number and so on. Has the strong software function: The dynamic / static weighing switch, the gross weight / net weight demonstration transformation, the date revision and the demonstration, the vehicle number / goods number hypothesis and the demonstration, the frequency / accumulative demonstration, the graduation value choice, the tare, , Zero, automatic / manual switch, weighing calibration, parameter setting and modification, shift exchange, storage, storage data access, removal and so on.
