Belt scale for bulk material, conveyor belt for transporting the continuous dynamic measurement, mainly the acquisition of two parameters,
one weight signal, and the other is the speed signal.
By weight signal is installed on the belt conveyor weighing scales rack sensor conversion speed signal is converted by the motor speed sensor.
The entire system comprises a belt conveyor, the weighing scale aircraft, weighing sensor, speed sensor, signal cables, display instruments.
Thus to make the belt measurement scales accurate, we must make more impact, the accuracy of the places to meet the accuracy requirements
of debugging state.
First, belt conveyors, belt conveyors requires rotation of the roller to be flexible, beating smaller belt run Partial try to control the small-scale,
belt joints should be smooth, and each segment of the weight of the belt tension as much as possible balanced, belts plus anti-deviation
device and a belt cleaning device, so that the belt changes as small as possible.
Second, the weighing scale aircraft, requiring power transmission scale aircraft to be linear, mechanical structural rigidity better, scale aircraft
to be cleaned regularly, so as not to affect the belt changes.
Third, weighing sensors, sensor accuracy must be high, better than linear, creep becomes smaller.
Fourth, the speed sensor, requires that the sensor not slip, turn to be flexible.
Fifth, the signal cables, requires the use of copper conductor shielded cable to reduce signal interference, display instruments, instrument
performance for stability, fully functional.
Just not enough to do more than five points, electronic belt maintenance is also critical to maintain good accuracy is high, poor maintenance,
precision to the end, even not achieve the measurement requirements.
