A good instrument technician should be familiar with process control schemes, right?

There is a meter technician in our unit who is extremely skilled. Do you know how much work he’s done? A few days ago, during the construction of an engineering project, as a colleague on the owner’s project team, I was greatly impressed by his dedication: he took the initiative to contact the manufacturers to obtain information regarding instrument selection and delivery ； He took the initiative to search the manufacturer’s website online to learn about its capabilities and promotional information, as well as information on similar companies ； He took the initiative to communicate with the general contractor regarding instrument information, and the person in charge of instrumentation and electrical systems at the general contractor’s side often sought his advice on technical and installation issues ； He took the initiative to communicate with the subcontractor regarding the issues with instrument installation ； Keep a close eye on some important instruments personally. He even went ahead and installed the instruments for on-site construction himself ； He remembers very clearly the model and number of each gauge chart ； He also acquired extensive knowledge of production processes ； If there are instrument problems or electrical issues in production, whether it falls within his responsibilities or not, as long as he is aware of them, he will say something to help others. In production, he solved many problems that undergraduate students, experts, and postgraduate students specializing in instrumentation and electrical engineering were unable to resolve. But he is just an ordinary instrument inspector; he doesn’t have any subordinates. Because he doesn’t like to ingratiate himself; he just does his work. Because his first degree was from a technical school, and it wasn’t in the instrumentation field. Because he currently does not have any technical professional title. Because it is a central state-owned enterprise that places great emphasis on educational qualifications and relationships. Even though he has 16 years of work experience, it’s still the same ； The total monthly income is around 2,300.

What is this trying to convey upstairs? That state-owned enterprises harm talented people? Or that there is a lack of respect for those with excellent technical skills but no formal education? Or is it trying to suggest that this respected veteran in the field of instrumentation has a personality that doesn’t fit into today’s social environment?

You definitely need to know it! If you don’t understand it, then what’s the point of having controls? The instruments serve as the means to meet process requirements!

Only after gaining a thorough understanding of the process can professionals in process control perform their duties effectively. This is the conclusion of my many years of experience.

This is a real friend of mine. Do you know what the general contractor plans to offer him: a monthly salary of 10,000 yuan, plus management responsibilities. But he didn’t agree. In short, it comes down to one thing: there must be a passion for instruments and a fervent dedication to studying them, without considering anything else. Do you think it’s good to study process engineering and production control? The clever reader can discern profound insights from answers that are never direct. How many people in life will tell you insightful truths? It’s just a simple way to answer your question! ! ! Impatient and superficial readers naturally become impatient with long answers and narratives. Because he can’t understand it. Hehehe! ! !

Those who work with instruments don’t understand the manufacturing processes, which makes it difficult to carry out analysis and processing. Those who are familiar with DCS but not with instruments will end up creating substandard results

I believe that instrument technicians should possess the following knowledge: 1. Drawing reading skills (instrument installation diagrams, panel wiring diagrams, terminal connection diagrams, simple electrical interlock diagrams). 2. The operational principles of common systems and PID flowcharts. 3. Safety regulations and procedures for handling various permits. 4. Basic computer operation skills. 5. Information on the pressure ratings and material types of pipes in common chemical processing equipment, as well as information on auxiliary materials such as welding electrodes. 6. Knowledge of piping systems and proficiency in using various tools and equipment. 7. Principles of several major types of instruments (level gauges, temperature gauges, pressure gauges, transmitters, flow meters). 8. Principles of various valves. Instrument technicians should have the following capabilities: 1. Familiarity with the structure of computer hardware and software, along with the ability to master various DCS programming methods through training. 2. Understand complex control diagrams (ladder diagrams, sequence control diagrams). 3. Familiar with various instrument selection catalogs. 4. Possess certain English reading skills and verbal communication abilities, as well as familiarity with various office document formats.

It is certainly necessary to understand that the diagnosis of certain faults relies on knowledge of the process principles, media, parameters, and so on.

Having some understanding in all aspects makes it relatively easier to carry out work
