Just starting out with instruments and looking for advice?

Reply to 2# denghl: The Electrical and Instrumentation department deals with instruments and electrical systems. It seems that adjusting them randomly isn’t allowed when you first start working there, and it also seems like there’s a difference between what’s involved in instrument work and what’s learned in related courses! !

The difference between strong and weak points. But the basics are similar; it’s still basically doable……

Instrumentation and electrical engineering are two distinct fields; those who are not clear about these concepts refer to them as high-voltage and low-voltage electricity, which is a conceptual error. Those who studied electrical engineering and want to switch to working with instruments may find it a bit difficult to get started, as the basic courses taught in school are different. But with some effort, it is possible to learn; real dedication is required. Abandon the academic concept of distinguishing electrical and instrumentation systems based on high-voltage and low-voltage electricity!

First, go to a bookstore and buy a textbook on instruments for vocational schools or technical colleges, so as to gain a general understanding of the principles and methods for measuring the four main parameters. Then read carefully the instructions for the instruments used in work, and be sure to get the chance to put them into practice. Once you have some understanding, buy a university textbook on instruments and study it in detail. From what you say, I feel you work in instrument applications. If that’s the case, you need to focus on the content of the application. Finally, let’s talk about flow meters, which are the most complex. To make good use of flow meters, you need to learn the basic knowledge of fluid mechanics, especially the engineering significance of Bernoulli’s equation. This Bernoulli principle will also be very useful for you in learning about control valves in the future. Here’s this for your reference for now. It doesn’t matter if your major isn’t relevant. I know an elder who is familiar with technologies such as control, hydraulics, and even mechanics. Even I, who study automation, feel inferior in many aspects of control. But their major in college was physics.

The most important thing to learn in the instrumentation field is the process flow! ! ! It is necessary to understand the instruments: the primary meters on site, such as T/P/F/L/V, as well as other instruments like analyzers, and to know their working principles. Then learn about control systems.

Is it temperature, pressure, flow rate verification?

Start with process engineering; only by understanding the process flow can one gain a deeper understanding of the function of instruments.

There is a big difference between electricity and instruments. But no matter what major you choose, you need to do more hands-on work and learn more*. Ask more questions! To learn about instruments, I think one should start by understanding their principles!

I strongly advise you to ask your supervisor to transfer you to the electrical engineering field. From a professional perspective, there is only one reason for this: one should not try to use one’s own weaknesses to compensate for others’ strengths； Other specialized knowledge is not your main focus
