In chemical processing plants, there are an increasing number of complete sets of equipment, such as PLCs, large-scale units, and analysis booths. Many of these complete sets of equipment include instruments for various purposes. Let’s discuss how we can approach the study of these instruments within such equipment sets What are the different options available in your company for this? Encourage free expression······
1. It all starts with process engineering; without an understanding of processes, one cannot work in instrument control, and this is also why the field of instrument control is always demanding. That is, why is this device needed? ; How does this device serve the manufacturing process? ; What actions did the device take under operating conditions? ; What deviations or potential deviations, as well as hazards or potential hazards, will occur in the process in the absence of this equipment? ; This is a system-level issue. 2. What technology is used in this device? What is the setup method? What are the advantages? What are the disadvantages? How to improve it? Are there any other options? This is a device-level issue.
Instrumentation kits! Learn about them!
Among the instrument kits, I’ve seen the most of them in gasification units, where there are many such kits. For general instrument kits, one should start by studying the electrical circuits; after understanding the entire electrical schematic, then move on to studying the instrument control circuits. One needs to become familiar with all the AI, AO, DI, and DO points. Once the entire diagram is understood, it’s necessary to go to the control cabinet on site to figure out the wiring there and the path of the circuits, as well as to understand the function of the various modules and their operating methods. After that, it’s time to deal with common problems. The most important thing when it comes to analyzing a testing booth is to figure out how the air flow works inside it; in fact, the key is to work with the manufacturer to carry out adjustments
It is mainly the medium being measured. Factors affecting it, instrument wiring, methods for handling faults.
First, it is necessary to understand the working principle of the instruments, followed by the process flow. It is also important to record and analyze instrument failures and their solutions in order to accumulate maintenance skills.
First, one should understand the purpose, principle, and operation process of the unit, and then become familiar with and grasp the function of each instrument on it. The key is to be involved in every start and stop. Increase the frequency of inspections and maintenance. Preparation of spare parts is also necessary.

1. One must understand the working principle of instruments. I can understand most of the (important parameters) in the manual. 2. Understand the manufacturing process. The parameters of the process determine the selection of instruments. 3. Know how to install. Installation is a part of the instrument’s operation; different process characteristics require different installation methods. 4. Understand control. That is what is referred to as DCS/PLC, etc. At first, you don’t need to write code, but you must understand the programming principles of control systems. 5. Every instrument in use should correspond to a few common and well-regarded brands. 6. It should be possible to maintain them. It’s not enough to just be able to install something; knowing how to control it is also necessary. Only by using it in the field on a regular basis and carrying out maintenance can one understand what aspects need attention when determining the installation height, which in turn helps to improve the selection process. 7. Stay informed about the latest developments in the instrumentation industry. With technology advancing by the day, it is necessary to keep learning* in order to enrich oneself.
That’s what was said upstairs. There are many variations among instruments, each with its own distinct characteristics.
