Compared with analog electronic truck scale has the following characteristics: 1, with high accuracy, high reliability digital electronic truck scale weighing sensor error compensation using digital methods and highly integrated electronic components, available software for linear sensor, zero, comprehensive compensation rated output, drift, creep and other performance parameters, to overcome the random error using analog compensation, eliminating the impact of human factors on compensation, greatly improving the accuracy and reliability of the integrated sensor. 2, the output consistency error consistency, interchangeability analog electronic truck scale general analog sensor within 0.1%, while the digital sensor reached within 0.02%, or even higher, when the mass of the sensor parameters can be completely same, so it has good compatibility in the application, on a level III scale replacement of digital sensors, does not substantially affect its performance measurement. 3, with high stability, anti-interference ability thanks to integrated A / D converter circuit, digital signal transmission and digital filtering technology, signal transmission distance sensor is greatly improved, up to 1200 m, significantly enhanced anti-jamming capability, digital transmission distance sensor analog signal is very short, while the sensor housing (elastomer) itself is a good shield, only these two characteristics determine the advantages of its anti-jamming capability, greatly improve the stability of the sensor sex. 4, with self-recognition function, easy fault diagnosis due to the digital sensor with automatic collection of data preprocessing, storage and memory function, and has a unique tag, you can check the status of each sensor are after more than just the sensor parallel group scales, easy troubleshooting . 5, with high flexibility with standard digital communication interface (RS485), can be directly connected to the computer to work with the host, but also with standard industrial control bus connection, the group scales convenient and flexible.
