Instructions for use of batching scale instrument manufacturers

The batching scale instrument series weighing display is developed by a team of experts with many years of product development and field service experience in the field of weighing batching and automatic control. It integrates advanced microelectronic technology, digital communication technology, field bus technology, electromagnetic compatibility. Technology, surface mounting process and transparent design ideas, adopt a simplified panel design style, Chinese\/English menu-type operation interface, easy-to-maintain interface, rich functions, transparent data, definable ports, and multiple standard bus interfaces Optional, stable and reliable performance, strong anti-interference ability, small size, light weight, easy operation and maintenance, etc., is an intelligent, network-based weighing and batching controller, suitable for dynamic measurement and batching control for industrial and commercial purposes system.

Dosing scale meterIt is the development trend of factory automation to use the standardized field bus digital transmission mode to replace the traditional imitation transmission mode. In the currently running batching monitoring system, most of the monitoring layers of various DCS\/FCS systems use the field bus communication mode, while the digital The data exchange between the secondary instruments of the mining layer (including weighing batching controller, material level weighing display, etc.) and the DCS\/FCS system mostly adopts the traditional analog transmission method, such as 4-20mA analog quantity, Switch quantity, pulse quantity, etc. The traditional analog transmission method has many cables, the signal is susceptible to interference, the signal transmission error is large, and the data processing (such as "filtering processing") required by the system to obtain reliable data requires a large workload Many defects such as long time-consuming mining and disposal are bound to become the bottleneck affecting the operation efficiency and reliability of the monitoring system. If the fieldbus transmission method is used, on the one hand, the DCS\/FCS monitoring system can read the weighing and batching controller through the fieldbus at high speed and zero error. The real-time data (digital signal) and the control parameters of the configuration controller are used to ensure the efficient real-time and overall control effect of the system. On the other hand, all kinds of data are transmitted on a standard bus, thus greatly reducing the need for imitating the transmission method. The signal cable consumption and construction amount are reduced, and the cost of system construction and maintenance is also reduced, and the reliability of the system is improved (the fault points are greatly reduced).

Application scope of batching scale instrument: widely used in industrial process weighing and measurement such as cement, fertilizer, steel, electric power, mining, port and food. MW9X series weighing instruments are specially designed for

The dynamic continuous weighing equipment design can not only complete the feeding control alone, but also can be connected with the host computer or central control to form a weighing and feeding system. Load and belt speed to calculate the instantaneous flow and cumulative amount, compare the given flow with the instantaneous flow, and output a control signal to adjust the belt speed.

Main features of batching scale instrument:

External signal given amount: remote input analog signal to adjust the set point to stop flow control.

Speed ​​input: measure the belt speed and running conditions, and complete the basic calibration by setting internal constants.

Operation authority: 3-level password management (operator level, administrator level, manufacturer level)

Key operation: automatic password lock, separate menu operation and shortcut key operation

Multi-task operation mode: during operation, it does not affect measurement, PID control, output storage, data input and output

Weighing signal input: 1 channel, 24bitA\/D, 030mVDC or 0\/420mADC, according to user configuration

Load cell flexibility range: 0.53.0V\/V

Dynamic zero adjustment\/tare: take the average value of the unloaded belt weight in a complete belt running cycle, and store it as the dynamic zero value.
