Regarding instruments

I’m honored that you have chosen the instrumentation major; this field requires highly meticulous and comprehensive work. Detailed down to various screw and nut thread specifications, etc ； It is comprehensive to the point where you need to be familiar with the production processes, as well as possess knowledge in areas such as mechanical and electrical equipment, civil engineering, materials science, and computer automation. First, understand the categories of instruments, such as temperature, pressure, level, flow rate, control valves, secondary display instruments, control systems, etc. Then, further categorize each type of instrument; for example, temperature sensing instruments include thermocouples and thermal resistors ； There are remote types and on-site types, etc. Understand the symbols of various instruments on drawings. When I worked with the instruments, I wrote all of this down in my notebook. Instrument maintenance is a technically demanding task that requires strong practical skills; one needs to spend time on site with experienced technicians and colleagues, be active in carrying out tasks, ask questions frequently, and keep learning. Records, experience, and knowledge are all things that one accumulates for themselves. I’m not afraid of you asking; I’m afraid you won’t ask! You don’t have to understand it, but you can’t avoid learning, asking questions, or taking action. Wish you success in your work!

It seems fine to be able to enter Haichuan; studying hard, asking questions frequently, and thinking more will be beneficial for one’s master.

Instrumentation can be divided into two categories: field instruments and control systems. For field instruments, start by understanding those used in your own factory. As for control systems, they generally include ESD, DCS, ITCC – take your time with these; there’s no need to rush. Regarding software, it’s about knowing how to operate it, and the functions that are commonly used. First, figure out those basics before delving deeper into more complex topics. When learning, prepare three notebooks: the first is a diary to record what you did each day, how you did it, and why you did it that way. The second notebook is for jotting down any knowledge points you learn from books or during work. The third notebook is for recording problems you encounter; if you can understand them right away, that’s great, but if not, write them down first, then look up information online or ask experienced colleagues. It’s best not to ask colleagues everything, as this can annoy them. This way, problems won’t accumulate over time. In general, instrumentation involves a wide range of knowledge, so it’s important to build up your skills gradually. Also, try to learn more English, as there’s a lot of foreign-related content in the field of instrumentation

First, find some relevant books to read, such as manuals for instrument technicians and books on measurement principles. Participate in more practical tasks related to troubleshooting; be sure to record both the symptoms of the problems and the solutions used. Ask questions frequently – if you don’t understand something, ask for help. Don’t be afraid of being laughed at, as the knowledge you gain from that will still belong to you

I know a bit about field instruments; let’s improve together.
