The intelligent batching scale instrument is one of the main measurement parameters in the automation process of industrial production. Since the weight detection is carried out while the material is conveyed, there are often different weighing equipment for different conveying methods of the material. This article introduces the composition of the weighing instrument , Classification and several important weighing instruments - electronic batching scale instrument, quantitative batching scale instrument, electronic hopper scale, electronic truck scale, electronic rail scale selection points.

Batching scale instruments are usually classified by use, such as electronic batching scale instruments, quantitative batching scale instruments, electronic hopper scales, electronic truck scales, electronic rail scales, electronic crane scales, weight sorting scales, price label scales, quantitative packaging scales, intelligent combination scales , Quantitative accumulative scales, reduction scales, liquid filling scales, postal scales, electronic forklift scales, screw feeder scales, rotor feeder scales, continuous loss-in-weight scales, etc.

Among the above weighing instruments, there are relatively many applications of electronic batching scale instruments, quantitative batching scale instruments, electronic hopper scales, electronic truck scales, and electronic rail scales. This article will take these weighing instruments as examples to introduce the selection points.

Quantitative batching scale instrument is a special application method of electronic batching scale instrument. It not only needs to complete the weighing task of material quantity like electronic batching scale instrument, but also realize the automatic control task of material quantity or proportioning. It is usually a short belt conveyor provided by the manufacturer alone, and is equipped with equipment such as frequency converters to control the amount of materials.

QuantitativeintelligentDosing scale meterThere are usually 3 working modes: constant speed batching scale instrument, drag batching scale instrument, double-speed batching scale instrument. Constant speed batching scale instrument refers to the quantitative batching scale instrument of feeder speed regulation and belt conveyor constant speed mode. , suitable for quantitative batching scale instrument with small change range of flow setting value; drag material batching scale instrument refers to quantitative batching scale instrument without feeder, belt conveyor speed regulation mode, suitable for good flow performance, moderate humidity, It is more suitable for the materials fed by the belt feeder; the double-speed regulating batching scale instrument refers to the feeder, and the belt conveyor is a quantitative batching scale instrument with a speed regulation mode, which is suitable for high batching accuracy requirements and changes in the flow setting value. A wide range of dosing scales.

quantitative intelligenceDosing scale meterThe controller is generally divided into 3 modes: stand-alone controller, unit controller, PLC-type controller. The stand-alone controller is currently based on single-chip technology, with simple structure, flexible configuration, and one-to-one use with the quantitative batching scale instrument. ;The unit controller is based on the PC bus industrial computer, which has strong functions, intuitive and convenient operation, and the price is lower when the number of quantitative batching scale instruments is large. Because it is used in many-to-one, it is not suitable for use in places with high requirements for batching reliability. ; PLC type controller is based on PLC, which is widely used in the production process as hardware, and realizes the batching function through software configuration. Its hardware reliability is high, the configuration mode is flexible, the communication mode is diverse, and it has a high cost performance. , It is especially suitable for seamless connection with large PLC and DCS systems. For example, it can be connected to the host computer using fieldbuses such as Profibus-DP and DeviceNet.
