Select as follows:
Determine the load for which the load cell is to be used and choose from the table the next higher value in the standard range. We can customize load cells if a standard load cell is not suitable for a particular application.

With the development of automation technology, the initial PLC controllers can no longer meet the requirements of some large-scale projects, and in this situation, DCS control systems have emerged. DCS control system, also known as distributed control system, is a new type of computer control system compared to centralized control system. It is developed and evolved from centralized control system. In terms of system functions, the difference between DCS and centralized control systems is not significant, but the implementation methods of system functions are completely different.

The so-called DCS (Distributed Control System), also known as Distributed Control System (DCS) in China, will not be further discussed. Now, let’s talk about how beginners learn the DCS system, which is a common problem faced by all newcomers in the DCS industry. Below, I will share some of my opinions on DCS:

For DCS, the main concerns are the communication protocols of each part of the network; Redundancy (server, power supply, master control
Controller, important I/O module); How to configure the input and output characteristics of I/O. The commonly used I/O methods include analog input AI, analog output AO, switch input DI, and switch output DO. In addition, there are SOEs, PIs, etc. Among them, AI signals include RTD (thermal resistance signal), TC (thermocouple signal), 4-20MA signal (can also be 0-20MA, 0-5V). After understanding these, the next step is to learn configuration, practice and modify control schemes, and install schemes for the main controller (without affecting production).

Furthermore, by combining software and hardware understanding, you can quickly get started in controlling on-site production in practice. In the future, you can learn the DCS department
Communication between the system and PLC, MIS, SIS.

Suggestion for theoretical knowledge: The principle of automatic control (without delving into it, understanding PID is sufficient, as even basic PID may not be able to be applied to the field); Commonly used programming languages (FBD, LD, etc.) are naturally learned during the configuration process; Analog circuits and digital circuits are preliminary, but there is no need to delve deeper into this; Computer knowledge, especially network knowledge, ultimately, the development of DCS is entirely based on the rapid development of computer software and hardware. The above is only a brief analysis of Nanjing Ruipai Instrument for everyone, hoping to be helpful for your initial learning.
