Shanghai Ying Heng Weighing Equipment Co.,LTD
 Electronic belt scale 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.
    Weighing, bearing device will pass the gravity of the belt material to weighing transducer, weighing transducer output voltage(mV) signa which is proportional to the material gravity,
Amplification by the amplifierand converter into the digital quantity A, convert to the unit.Material speed input speed sensor, speed sensor output pulse that several B, also to the unit; Unit operate  A, B,then get the measurement of the material. Accumulative each measurement cycle, you will get the total amount of material.
    Weighing indicator divide into two types:digital display and Chinese characters display, Chinese characters display is the upgrade for digital type. Weighing indicator got cumulative and instantaneous flow display,automatic zero adjustment, semi-automatic zero adjustment, self-check fault, digital calibration, flow control, print and other functions. Display of Chinese characters in addition also shows speed.Chinese characters display can show the function,help people operate instrument better.

Make the essence of the breakthrough of  the long-term stability of the belt scales,weighing precision also have significantly improved.
    I fonts single point weighing transducer technology   Patent technology " I fonts single point sensor" make scales with stability and resistance to partial load performance.Its unique structural features guarantee the long-term stability of the belt scale.
    The manufacturing of this scale use special steel structure. New engineering design and standardized production, make its have extremely rich contemporary sense of pure and fresh look and compact  rational structure, parts versatility.
    Electronic belt scale is mainly consist of weighing part, tachometer part,calculation part and communication part.
    Weighing transducer on weighing bridge beams  detection the weight signal of materials on the belt.the calculation amplification, filtering the weight of the speed signals , A/D conversion into the CPU for integral operation, and then display the material flow and total weight instantaneous on the panel, the integrating instrument have optional function:networking, communication, print, DCS online and so on!

Model and meaning
    Common models: ICS-500 ICS-600 ICS-650 ICS-800 ICS-1000 ICS-1200 ICS-1400
    The ICS-14 high-precision electronic belt scale, full suspension weighing bridge,the digital signal transmission and processing technology, the dynamic cumulative error is less than ± 0.125%, applies to enterprise internal and external settlement, or other   occasions where require weighing accuracy high.

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.

Structural characteristics
    ◆ Full suspension structure, no trunnion fulcrum and movable parts, little maintenance;
    ◆ Unit component structure, less force transmission link, easy, convenient installation;
    ◆ Unique rectangular lever,good rigidity, without distortion, zero stability;
    ◆ Anti-lateral force,anti-horizontal force.Effectively reduce the effect that the belt running deviation and dropping material offset to the system precision;
    ◆ Four weighing transducer,small affected by slanting load, stable and high measuring accuracy.
    ◆ Weighing regional wide,using three groups or four groups  belt roller so that the belt  affect weighing precision small;
    ◆ Scale frame is made of stainless steel or anticorrosive processing, on the special corrosive occasion: the dust bigger and have acid, alkali, salt and so on,
    ICS-14 type electronic belt scale consists of four parts: ICS-14 type weighing bridge, weighing transducer, 60-12 C speed sensor and speed roller, YL2001 weighing controller.

Weighing Bridge

    ICS-14 weighing bridge is the moving parts of 4 groups great trust roller, the suspension structure, no trunnion fulcrum. Using rectangular pipe design, the whole weighing bridge has a high rigidity, and smaller self-weight,the area of dust-accumulation lowest.High precision resistance strain sensor chip installation and tensile site, to reduce the nonlinear error.Guarantee the stability of the system, the maintenance is few.Two beams provide support to weighing bridge by hanging four rumsfeld weighing transducer. Weighing bridge is four unit component structure, can be easily and quickly install, just need eight little bolt fixed it.

Basic part of electronic belt
    (1) belt conveyor drive unit (embedded loaded belt weigher manufacturers generally is not provided, but unless it belt weigher is incomplete, it can not work properly.)
    (4) signal acquisition, processing and control unit.
    For conveyor belt scales type, the whole machine belt conveyor is bearing device; For weighing desktop belt scale, its weighing table, weihging roller and the conveyor belt form the bearing device.
    Weighing transducer is the element transfer the gravity of the material into analog or digital signal . Weighing table and weighing transducer combination has often been called a weighing unit.As a dynamic measuring instruments electronic belt scale, speed sensor used to measure the running speed of the material is also an important components to ensure the accuracy of measurement .
    Signal acquisition, processing, and the control unit is an electronic devices used to receive, processing  signal  output by the sensor and gives measure results by the quality unit , and complete other reserve function.It can be a single meter (for example "dynamic weighing displaying controller"), also can be made by combination of several independent part (for example, the separation of the incentive power devices, sensors placed the signal collector and placed the product of the central control room is and the PC, etc.).In order to narrative, this volume tutorial often referred the signal acquisition, processing, and the control unit (whether single or combination) as the "display control device".
