Shanghai YingHeng Weighing Equipment Co.,LTD
Electronic belt scale equipment are divided into four kinds from the structure: multi-roller double-pole type, single-roller style, cantilever type, suspension type.The multi-roller double-pole type and suspension type which developped by our compny got the longest metering zone, 2 ~ 8 group roller measurement accuracy highest, has been widely used in the occasion that require highest accuracy and large flow measurement . All  belt scales are already determined speed, can adjust themselves.
    The electronic belt scales are equipped with special display, the electronic belt scale supporting displays is Chinese characters display, showed clear,is instantaneous flow shows, have automatic zero, semi-automatic zero, self-check fault, digital calibration, flow control, printing, and can also display speed and many other function!  Researchers operation can be more convenient.
    Electronic belt scales is consist of scale frame, speed sensor, high precision measuring heavy sensor and electronic belt scale control and display instrument ,continuously dynamic weighing work  to solid raw material.
    In addition, another main use of  electronic belt scale is can be installed on the shelves of weighing bridge conveyor rack, when the material passing, measuring roller detect the belt material weigh working weighing transducer through leverage,Produce a voltage signal which is proportional to the belt load. Speed sensor connect directly to large diameter speed roller, provide a series of pulses, each pulse represent a leather belt motion unit, pulse frequency is proportional to the belt speed. Weighing instrument receiving signals from weighing transducer and speed sensor, get a transient flow value and cumulative weight value through the integral operation, and display respectively.

Eighth,The system has the strong combination and expand flexibility according to user requirements.
Last,System has strong network adapter ability, can adapt to all kinds of network requirements.

New weighing error theory
    The main factor which influence long-term stability of belt scale is belt tension and the stability of scales frame structure. Through the research we found: Through processing the array type belt scale data units can made array internal belt tension influence less over 90%, namely basic belt tension completely compensated, according to this, form a new belt weighing error theory.
    In the above guidance, the original belt scale stiffness, roller eccentric degrees, roller with the influence of material, and many other requirements can be ignored, match with high stability of the single point suspended weighing platform, can achieve high precision and high stability of the belt weighing measurement results.
    Common models: ICS-500 ICS-600 ICS-650 ICS-800 ICS-1000 ICS-1200 ICS-1400
    ICS-14 type high precision electronic belt scale, adopt the whole suspended weighing bridge, digital signal transmission and processing technology, dynamic accumulative error less than plus or minus 0.125%, suitable for enterprise's internal and external settlement, or other occasion which require higher accuracy.

Working principle
Weigh bridge installed on the shelves of weighing bridge conveyor rack, when the material passing, measuring roller detect the belt material weigh working weighing transducer through leverage,Produce a voltage signal which is proportional to the belt load. Speed sensor connect directly to large diameter speed roller, provide a series of pulses, each pulse represent a leather belt motion unit, pulse frequency is proportional to the belt speed. Weighing instrument receiving signals from weighing transducer and speed sensor, get a transient flow value and cumulative weight value through the integral operation, and display respectively.
