1. Design of Scale Body Structure
The structural design shall be characterized by simple structure, convenient installation, good anti eccentric load performance, accurate force value transmission and reliable limit. The more idlers, the higher the precision. For example, the precision of the electronic belt scale with four idlers is higher than that of the electronic belt scale with three idlers, and the precision of the electronic belt scale with three idlers is higher than that of the electronic belt scale with two idlers.
2. Improve the accuracy of the special weighing sensor for belt weigher
The weighing sensor is an important part of the electronic belt scale. It is required that the weighing sensor selected for the electronic belt scale must have the characteristics of good fatigue resistance, high impedance, high bridge supply voltage, high sensitivity and high resolution, otherwise it is unstable.
The worse the stability and accuracy of the weighing sensor, the worse the stability and accuracy of the electronic belt scale.
3. Correctly install and debug the belt scale
In order to ensure the accuracy and reliability of the electronic belt scale, special attention should be paid to the selection of appropriate environmental conditions for the installation of the scale frame and instrument of the electronic belt, such as small vibration around, low relative humidity, weather erosion and sunlight resistance, and especially the distance from strong magnetic fields and high heat sources, with good environmental sanitation. The scale frame of the electronic belt scale shall not be too close to the driving drum and the blanking point, and must meet the requirements of the electronic belt scale.
4. Constant ductility calibration
In order to ensure the dynamic measurement accuracy of the high-precision electronic belt weigher system, the key measure is to calibrate continuously. The purpose of calibration is to make the accumulated display value of the instrument coincide with the actual value to a large extent, and the error cannot exceed the specified indicators. There are many calibration methods, such as dynamic hanging weight method, weight trolley method, chain weight calibration method and physical calibration method.
