Beginner in automatic control instrument design

Read the specifications more often, and look at the manufacturer’s samples more often

In the design of automatic control instruments, it is first necessary to understand the structure and principles of various instruments, as well as the operating conditions for which they are suitable； Another thing is to understand the manufacturing processes of the industry you are designing in, the more detailed, the better. This is particularly important for design. Third, it is necessary to understand the relevant standards and laws and regulations ； Fourth, understand the advanced technologies in this field as well as related cutting-edge technologies ； Fifth is to be well-versed in the relevant knowledge of electrical engineering. In short, there is no end to learning in the field of instrument automation. It’s necessary to keep updating one’s knowledge.

It’s best to have previous samples, or you can download them from the internet. First, determine the requirements for the instruments, and then create the instrument data sheet (for use by manufacturers in making selections and purchases), the DCS monitoring data sheet, the DCS specification sheet, and the instrument circuit diagrams. Based on these, other documents such as those related to construction and installation, material lists, air supply details, and gas alarm information can be prepared later. Every design firm follows a similar approach. This is what our control systems department needs to handle. It’s useful to have someone to guide you when you first start in this field. I’m not sure if you have any prior experience with instruments, or if you went straight to a design firm after graduation; having some on-site experience would be even better, as it allows you to convert on-site information into written documentation. You also need to understand what types of instruments exist—AI/AO/DI/DO, etc. There are many different types of instruments, and it’s important to know their principles as well. Take your time

Take a closer look at the design specifications; they are the prerequisites for design

1. Start with the basics and understand the principles of commonly used instruments (multiplication*). 2. Examine the specifications for instrument selection, applicable conditions, materials, type, etc., as well as various other relevant standards. It is important to focus on understanding the definitions; one should not rely solely on the conclusions, as this can lead to overlooking certain details or misinterpreting them. 3. Learn while doing, and pay attention to summarizing and accumulating knowledge. 4. Design is a process of continuous accumulation and refinement.

First, it is necessary to get more exposure to field instruments, and second, to learn more about various design specifications.
