Why digital truck scales? Hebei truck scale manufacturers for you to introduce it:
For electronic truck scale with digital sensor, the adjustment of the Angle difference of the scale body only needs to be made on the instrument or computer to adjust the coefficient of the corresponding sensor (or it can be done automatically by the instrument or computer). Due to the superposition of digital signals, the output signal is large and the signal-to-noise ratio is much better than the analog sensor, which improves the accuracy of measurement data.
Digital electronic truck scale has the function of fault self-diagnosis, which is convenient for fault treatment and maintenance. In the scale body using analog sensor, to replace a sensor, the whole scale body needs to be adjusted and calibrated again, and the digital sensor has good consistency, no need to adjust the original measurement after replacing the damaged digital sensor, only the number of the sensor in the field can be trimmed. Because of the digital signal output by each sensor, it has strong anti-interference ability and avoids the metering error caused by the continuous connection error of the analog sensor and the temperature change of the impedance of the long-distance transmission line.
Due to the digital sensor response speed and communication speed is not very high, only suitable for the use of static electronic truck scale. Finally, through the digital transformation of the electronic truck scale, the main convenient debugging and maintenance work, to ensure the accuracy of measurement data and operation stability n, but due to A/D conversion within the digital sensor.
CPU and communication interface increase the cost and make the distribution cost too high. There is A digital junction box with analog sensor, which is suitable for multi-sensor metering system. The analog signal output by the sensor is converted into digital signal through A/D, making the analog sensor have the function of digital sensor. Because a truck scale only needs a digital junction box, so the cost is not very high, in the multi-sensor electronic scale, has a wide range of promotion value.
