Automatic weighing solution for chemical industry

1、 Preface

The chemical industry has a very close relationship with industry and agriculture, national defense, people's lives, and science, and is an important industrial industry closely related to economic construction and people's lives.

The weighing and measurement required for raw materials entering the factory, production and manufacturing processes, and finished products leaving the factory, especially in the chemical production process, with the diversification of formulas and the continuous improvement of ingredient accuracy requirements, traditional manual ingredient methods can no longer meet the actual production requirements in terms of production efficiency and accuracy.

With the trend of modern enterprise scale and group development, the production capacity of chemical enterprises is growing exponentially, and the degree of automation is also increasing. At the same time, in the 21st century, which emphasizes "people-oriented", safety production has now been placed at a higher height, and the application of unmanned automation systems is becoming more and more widespread, which also puts forward higher requirements for the automation of weighing systems.

2、 TRUSTAR's Automated Weighing Solution

In response to the above characteristics of the chemical industry, Shenzhen Chengtongda Technology Co., Ltd. has proposed an automated weighing system based on the concept of full integration based on its more than ten years of experience in the automation industry. In the entire weighing system, we focus on higher automation level, simpler on-site wiring, faster and more reliable data transmission, more accurate historical records, more convenient operation methods, and more remote monitoring.

1. System composition

● Upper computer system based on industrial configuration software;

● On site touch screen display of function *;

Reliable Siemens PLC system;

Weighing electronic module integrated into Siemens automation system;

High precision and high reliability weighing sensors.

3、 Characteristics of TRUSTAR Automatic Weighing System

1. Complete set nature

Total Integrated Automation (TIA) combines high integration uniformity and openness, standardized network architecture, unified programming configuration environment, and highly consistent data integration, achieving horizontal and vertical information integration for enterprises;

Communication standards, component-based automation technology, PC automation solutions, and IT integration truly open up the product and service scope of the entire automation market;
Fully integrated schematic diagram:

2. PC based human-machine interface software system

● A running interface with Windows Vista theme style and appearance;
New controls: historical data trends, alarms, formulas, etc;
Object based programming mode, panel technology;

● Free integration of advanced user management tool SIMATIC Logon;
Enhanced security, supporting Windows Firewall and virus scanning;

3. SIMATIC PLC Control System

The TRUSTAR automatic weighing system integrated into the PLC system can directly and reliably control the actuators such as pumps and valves related to weighing, and integrate with the automation system of the entire factory through communication methods such as PROFIBUS and Ethernet, reducing on-site wiring, reducing system failure rates, increasing system flexibility, and improving system response speed.

The automatic weighing processing module and I/O control module can be expanded according to the number of scales on site and the equipment that needs to be controlled, avoiding the limitations of traditional weighing control instruments (such as secondary meters) in terms of control functions;

4. SIWAREX weighing electronic module integrated directly into the PLC system as a functional module

Can be used for various SIMATIC solutions, whether integrated as modules in S7 programmable controllers or used as distributed I/O with SIMATIC S7 or C7.

Because direct integration does not require any additional coupling modules, the system integration cost is low

Adopting a unified system concept with low configuration costs

● System - Compatibility module response (diagnostic interrupt, command output disabled, etc.)

● Expand with standard SIMATIC components to create a customized low-cost weighing system

● High equipment utilization rate

● Adopting interlocking technology, easy to install

● Adopting a compact design with low space requirements

4、 On site application

We have * solutions for both large-scale weighing and weighing in hazardous areas

100T weighing sensor and installation unit intrinsic safety sensor in hazardous areas

Explosion proof safety barriers are applied on site, and the Siharex weighing electronic module is integrated into the PLC system

5、 Typical case

At Jinpu Jinhu Chemical in Nanjing, in order to ensure efficient operation and product quality of the factory, it is necessary to require production process standardization and high automation. Users adopt an automated weighing system based on the fully integrated concept.


At BASF Polyurethane Specialty Products Co., Ltd., the automated weighing system based on the fully integrated concept has also been well applied.

6、 Application prospects

With the improvement of automation level and automation degree, automated weighing technology based on the fully integrated concept will gain more and more favor and trust from users. Continuing innovation in weighing technology based on the concept of full integration, such as adding fuzzy PID control for system optimization, to achieve higher system accuracy and response speed, further optimize the process flow, and improve product quality.

Compared to traditional weighing systems based on secondary meters, this flexible, concise, and reliable automated weighing solution will also be easier to meet increasingly high production requirements and gain the favor of users.
